Do you have a huge .NET framework application (Web forms, MVC) that relies on authentication and/or System.Web types that you would ideally like to migrate to .NET Core, but just don't have the bandwidth to put everything on hold while you rewrite the entire application on a new framework? If so, you might be interested in an exciting new project from Microsoft - SystemWebAdapters for ASP.NET Core - that enables you to incrementally migrate your old application, endpoint by endpoint.

Working With Zip Files In ASP.NET MVC

calendar_today 10 February 2017 07:41

ASP.NET MVC

Since ASP.NET 4.5, zipping and unzipping files can be done with classes from within the .NET framework. Despite that, nearly all examples that illustrate working with zip files in ASP.NET applications feature third party open source compression libraries. This short article attempts to correct that by demonstrating the use of the System.IO.Compression classes to unpack an uploaded zip file, and to create one for download in an ASP.NET MVC application.

Free SSL Certificates On IIS With LetsEncrypt

calendar_today 02 February 2017 07:44

ASP.NET MVC ASP.NET Web Forms ASP.NET Core

If you have forms on your site that take a user's personal details, you should protect the page by running it under HTTPS. That way, any data that's posted from the form (email address, credit card number etc) is encrypted and hidden from prying eyes. It's not just e-commerce sites that should be protected. Intranets and other line of business apps that require authentication, blogs with comment forms that ask for email addresses and so on. The main barrier to this in the past has been the cost of the digital certificate (SSL Certificate) that asserts that you are who you say you are. LetsEncrypt is a free, automated, and open Certificate Authority that removes this barrier.

Loading ASP.NET Core MVC Views From A Database Or Other Location

calendar_today 21 July 2016 08:56

ASP.NET MVC ASP.NET Core

For the vast majority of ASP.NET Core MVC applications, the conventional method of locating and loading views from the file system does the job nicely. But you can also load views from other sources including a database. This is useful in scenarios where you want to give users the option to craft or modify Razor files but don't want to give them access to the file system. This article looks at the work required to create a component to obtain views from other sources, using the database as a working example.

Now that the RTM of ASP.NET Core has shipped, the ASP.NET team are looking at the features that were left behind including SignalR and Web Pages. The ASP.NET Core road map always had those items scheduled for inclusion in the first major release after RTM, which will be ASP.NET Core 1.1. Recently, the ASP.NET Team provided an update on GitHub on the goals driving the next version of Web Pages which provides an interesting insight into the potential features of the framework.

Implementing SQL Server Full-Text Search In An ASP.NET MVC Web Application With Entity Framework

SQL ADO.NET ASP.NET MVC Entity Framework

The search facility on this site has been rudimentary at best. I have recently upgraded it to take advantage of the Full-Text Search feature in SQL Server. Although it is still a basic implementation, it is a vast improvement on the search system that existed before, which was based on Entity Framework dynamically generating SQL LIKE clauses. This article describes how I got SQL Server Full-Text Search up and running.

The Best Way To Import Data From Excel To SQL Server via ASP.NET

ADO.NET ASP.NET MVC ASP.NET Web Forms ASP.NET Web Pages EPPlus

I've seen a lot of questions about the best way to import data from uploaded Excel files to a SQL Server database in an ASP.NET application. Most solutions involve the use of the JET or ACE OLEDB providers to read data from the saved Excel file, and some even show how to use Office Interop to obtain the data. However, all of these solutions rely on additional components being installed on the server, and they also require the uploaded file to be saved somewhere, even temporarily, which creates an additional maintenance task. The solution that follows makes use of a Nuget package that gets deployed with your application and can work with streams, so the uploaded file doesn't need to be saved. It is, in my submission, THE best way to import data from uploaded Excel files to SQL Server in an ASP.NET application.

Every time I need to work with the contents of text-based files in an ASP.NET application I invariably start off thinking about using the various static methods on the System.IO.File class to extract the text and then some string manipulation or Regex to parse the content into some kind of structure. And, just in time, I remember the TextFieldParser class that hides itself away in the Microsoft.VisualBasic assembly. The purpose of this article is to introduce this component to a wider audience, but also to serve me as an aide-mémoire in terms of the basic usage, which I always have to look up.

TagHelpers is one of the new features introduced in MVC 6, part of ASP.NET 5. They are used for generating reusable pieces of UI that require some kind of server-side processing. I took a closer look at the built-in collection of TagHelpers in my last article, Introducing TagHelpers in ASP.NET MVC 6. This article shows how to create your own custom TagHelpers. It will illustrate two ways of doing so: through parsing custom attributes; and by binding properties on the TagHelper.

TagHelpers is one of the new features introduced in MVC 6. The TagHelper's role is similar to the one played in previous versions of ASP.NET MVC by HtmlHelpers: they are designed to simplify the work required to author views that need to respond dynamically to the data provided to them. However, the way in which they work and their impact on view design is very different to HtmlHelpers.

ASP.NET Core is being designed so that your application is only dependent on features that it actually needs. This is achieved in large part by creating a composable framework, where the developer opts in to non-essential features - a number of which are baked in to traditional versions of ASP.NET. One of the features that this applies to is Session State. This article looks at how to obtain and use session state in ASP.NET Core applications.

The SimpleMembershipProvider, Secure Passwords And The Crypto Helper

calendar_today 27 September 2012 13:39

ASP.NET MVC ASP.NET Web Pages WebMatrix

Some people have questioned the security of the ASP.NET SimpleMembershipProvider's storage of passwords. The cause for concern seems to stem from the fact that the PasswordSalt field in the standard membership table is unused by the SimpleMembershipProvider, whereas it is used by, for example, SqlMembershipProvider. So what is the PasswordSalt field, and why should the fact that it isn't used raise an eyebrow?

Cannot use a lambda expression as an argument to a dynamically dispatched operation

calendar_today 18 September 2012 08:08

LINQ ASP.NET MVC ASP.NET Web Pages WebMatrix

Since the introduction of the Web Pages framework, ASP.NET has been making use of the dynamic type introduced in C# 4.0. Along with that comes some new error messages which at first glance don't make a lot of sense - mainly because they are unexpected. I have already looked at how dynamics do not support extension methods, and a recent question in the ASP.NET forums illustrated another way in which the dynamic type can catch you out.

View Model Design And Use In Razor Views

calendar_today 26 May 2012 23:21

ASP.NET MVC Razor

The recommended practice for transferring data to and from views in ASP.NET MVC is to use a View Model. But what is a View Model? How to you design one and how should they be used? This article attempts to provide answers to those questions.

Nested Layout Pages with Razor

calendar_today 17 December 2010 13:27

ASP.NET MVC ASP.NET Web Pages WebMatrix Razor

Razor Layout pages are the equivalent to MasterPages in ASP.NET Web Forms and the Web Forms View Engine within ASP.NET MVC. Just as it is possible to nest MasterPages, it is also possible to nest Razor Layout pages. This article explores the process required to achieve nesting of Layout pages using the Razor View Engine in MVC 3, or WebMatrix Web Pages sites.

Named Anchors And MVC Urls

calendar_today 14 June 2010 10:15

ASP.NET MVC

Named Anchors are used to generate links to specific locations within a web document. Unless you are careful, you may end up having a little trouble getting these to work using the MVC LinkExtension helpers.

Google Sitemap Generation From A Custom SiteMapResult

calendar_today 31 May 2010 20:42

ASP.NET MVC

My previous article showed how to use a custom ActionResult and the classes within WCF to generate an RSS feed. There are no similar classes to help build a valid Google Site Map for an ASP.NET MVC application. So here's how your can build your own.

Rss Feed Generation From a Custom RssResult

calendar_today 31 May 2010 09:14

ASP.NET MVC

When I looked at producing RSS Feeds in ASP.NET MVC before, I used the ContentResult method to return XML. Best Practice suggests that you should create a new ActionResult if required. So this article looks at creating an RssResult, and a different way to generate the feed itself.

Validating the Contact Manager with MVC 2.0 And VS 2010

calendar_today 29 March 2010 22:17

ASP.NET MVC

The MVC 2.0 Framework was finally RTM'd on March 11th 2010, so I took the opportunity to update my Contact Manager application with some of its new features. While the focus of this article is validating the Model using DataAnnotations, I also touch on one or two other new features in the latest release.

ASP.NET MVC v. Web Forms Debate - My View

calendar_today 22 February 2010 21:53

General ASP.NET 3.5 ASP.NET MVC

It seems that the whole world (and Margate) is having its say on which is better - MVC or Web Forms. Scott Guthrie posted his views on technical debates in general, and then contributed his thoughts on MVC v. Web Forms. Ian Cooper has an interesting contribution to make to the debate too. Rob Conery (formerly of Microsoft) posted probably the most linked to opinion on the matter. (There - I've just added another link...) A lot of other blog posts around scream that MVC is better because its better. One even tries to posit the notion that some kind of score card approach can help you decide.

ASP.NET MVC is not all about Linq to SQL

calendar_today 21 February 2010 08:21

ADO.NET ASP.NET MVC

Pretty much every sample application that illustrates ASP.NET MVC uses Linq To SQL or the Entity Framework as the data access method. I've seen a number of questions posted to the forums at www.asp.net asking if there are any alternatives, and indeed there are. This article will look at using plain ADO.NET within a data access layer to provide dynamic content to a typical small CRUD application.

Get The Drop On ASP.NET MVC DropDownLists

DropDownLists in ASP.NET MVC seem to cause a fair amount of confusion to developers fresh from Web Forms World. This article looks to provide you with all (well, most) of what you need to know to get your DropDownLists working in ASP.NET MVC.

ASP.NET MVC - Prevent Image Leeching with a Custom RouteHandler

calendar_today 25 December 2009 22:31

ASP.NET MVC

Have you ever noticed an unusually high number of requests in your web server log files for image files? It may well be that someone is linking to your images from their own site, and basically stealing your bandwidth. Here's how to implement a custom RouteHandler within an ASP.NET MVC application to prevent people leeching your images.

ASP.NET MVC Uploading and Downloading Files

calendar_today 21 December 2009 22:29

ASP.NET MVC

If you come to ASP.NET MVC from a purely ASP.NET Web Forms background, one of the first things you are likely to notice is that all those nice easy Server Controls have disappeared. One of those is the FileUpload, and its absence seems to cause a few problems. This article looks at how to upload files to the server in an MVC world, and how to get them back from the server to the user again.

Book Review - Professional Enterprise .NET

ASP.NET 3.5 ASP.NET MVC Book Review

I reviewed an ASP.NET Architecture and Design book recently. It was OK. I felt it was a bit thin, and didn't cover topics beyond beginner level. Then I got sent a review copy of another book: Professional Enterprise .NET. Having read it, this is the book that the previous book should want to be when it grows up.

Dependency Injection and Inversion of Control with ASP.NET MVC

calendar_today 10 October 2009 22:46

LINQ ASP.NET MVC Entity Framework

As you delve more into ASP.NET MVC you start to come across a whole new way of doing things that Web Forms development didn't really expose you to. Inversion of Control (IoC) and Dependency Injection (DI) are two phrases that crop up a lot in the MVC space. So what are they all about? And should you care?

iTextSharp ASP.NET MVC

If you are developing a business application using ASP.NET MVC, and need to produce some kind of dashboard-style reporting, the Chart Controls from Microsoft are a good place to start. Having a summary in some form of document, say a PDF is also a common requirement. This article introduces you to satisfying both needs.

There are a number of jQuery star rating plugins to choose from. All have their pros and cons. For this site, I decided to implement the one from FyneWorks because it allows for split stars. Here's how I did it.

ASP.NET MVC - Battle of the Books

calendar_today 27 July 2009 13:25

General ASP.NET MVC Book Review

There's always a splurge of new books that come out around the RTM of any new ASP.NET related technology. Authors all over the place are burning the midnight oil, cursing the changes from one CTP to the next, through to Betas and hoping against hope that the Release Candidates and final RTMs aren't stuffed with "breaking changes" which inevitably mean total rewrites of whole sections or chapters in their draft. And then the race between the publishers is on, as each tries to get their offer to market before the others. Here, I look at three of the titles that were published around the time that ASP.NET MVC was launched, and give my judgement on how they fare in covering not only the core Framework but the key features that ASP.NET MVC is designed to offer:

RSS Feeds and Google Sitemaps for ASP.NET MVC with LINQ To XML

calendar_today 10 July 2009 22:43

LINQ ASP.NET MVC

For the majority of personal web sites, two uses of XML are commonplace: creating an RSS feed and a Google Sitemap. Here, I look at how to create both of those using LINQ to XML for an ASP.NET MVC web site.

ASP.NET MVC, Entity Framework, Modifying One-to-Many and Many-to-Many Relationships

calendar_today 28 June 2009 21:37

Building on my previous article, which looked at adding data with one-to-many and many-to-many relationships via the Entity Framework, here's a look at how to modify that data within an ASP.NET MVC application.

ASP.NET MVC, Entity Framework, One-to-Many and Many-to-Many INSERTS

calendar_today 17 June 2009 21:55

ASP.NET MVC Entity Framework

Taking on two new technologies - ASP.NET MVC and the Entity Framework - at the same time was bound to provide some "interesting" moments. Getting data out via EF has so far been pretty straightforward. But when it got to building the back end of my site, I had some fun trying to manage INSERTS with One-To-Many and Many-To-Many relationships.

Handling Legacy URLs with ASP.NET MVC

calendar_today 08 June 2009 07:37

ASP.NET MVC

According to Google's Webmaster tools, there are about 15,000 incoming links to my site. 13,000 of those reference a .ASPX file on disk. When I convert to MVC, with new Search Engine Friendly urls, all those links will break unless I do something about it. Presenting users with a 404 - file not found is not an option. I need to show them the content they were expecting, and update Search Engines with the news that things have changed. Here's how I will be managing those Legacy URLs.

Creating a Tag Cloud using ASP.NET MVC and the Entity Framework

calendar_today 01 June 2009 07:26

ASP.NET MVC Entity Framework

A Tag Cloud is a visual depiction of Tags or categories on a web site. CSS is used to set the variable font size of each Tag to illustrate its relative frequency or popularity within the site. As part of the migration of my site to ASP.NET MVC, I am introducing one to replace the Categories navigation that appears on the left hand side of each page, which contains a count of items within each category.

A Degradable jQuery AJAX Email Form for ASP.NET MVC

calendar_today 29 May 2009 15:58

AJAX ASP.NET 3.5 jQuery ASP.NET MVC

Pretty much every web site on the Internet features a form for users to provide feedback via email to site owners. This site is no different. Migrating to ASP.NET MVC requires a slightly different approach to that used by Web Forms development, so this article looks at one way to implement a web site contact form using the MVC framework and jQuery that degrades nicely. AJAX functionality is said to be "degradable" if a way is provided for the process to work, even though users don't have Javascript available to them.

ASP.NET MVC Partial Views and Strongly Typed Custom ViewModels

calendar_today 11 May 2009 07:06

ASP.NET MVC Entity Framework

I'm in the process of rewriting mikesdotnetting.com using the ASP.NET MVC framework. It's an interesting experience, in that this is my first exposure to MVC. The first stumbling block I encountered was how to pass data in a satisfactory way to Partial Views which only represent part of the data that is to be displayed in the View. Since I struggled to find clear guidance on this, I thought I would share a way to do it.
