Entity Framework ASP.NET Core

Redesigning a framework from the ground up provides an opportunity to implement an improved API. The team working on Entity Framework Core have certainly grabbed that opportunity in respect of the DbContext class, which sees a bunch of new data manipulation methods not available in Entity Framework 6 or earlier.

Entity Framework Core TrackGraph For Disconnected Data

11 October 2016 21:40

Entity Framework ASP.NET Core

Entity Framework Core is the new lightweight version of Entity Framework designed to work with .NET Core applications. Just like ASP.NET Core, it has been rewritten from the ground up, and includes some new ways of doing things. One of those is the introduction of the TrackGraph method for handling complex data in disconnected scenarios such as MVC or Web API applications.

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

21 July 2016 08:56

ASP.NET MVC ASP.NET Core

For the vast majority of 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.

Entity Framework Code First and Stored Procedures

16 June 2016 07:38

Entity Framework

A key reason behind the decision to use an ORM such as Entity Framework for your data access is to reduce or eliminate the need to write SQL as part of the development process. Nevertheless, there are times when you might need to make use of database stored procedures, and Entity Framework 6 Code First provides support for using existing stored procedures as well as generating new ones.

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

13 May 2016 08:13

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

14 April 2016 13:42

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.
