Edmx File On Visual Studio
Visual Studio 2017 has many project type options, and not all of them support the Entity Framework user interface to generate the Entity Framework Data Model (EDMX) file. If you create an ASP.NET Web Application(.NET Framework) you can add the EDMX file to it. The .NET Core projects do not support the Entity Framework Data Model creation.
- 1 - Add an.edmx file to your project. For information about adding an.edmx file to a project, see How to: Create a New.edmx File (Entity Data Model Tools) and How to: Add an Existing.edmx File (Entity Data Model Tools). 2 - Build the conceptual model.
- Set a build action. To set the build action for a file, open the file's properties in the Properties window by selecting the file in Solution Explorer and pressing Alt + Enter. Or, right-click on the file in Solution Explorer and choose Properties. In the Properties window, under the Advanced section, use the drop-down list next to Build Action.
Hi, Double click the edmx file, right-click the stage and select 'Update Model From Database', select your Views and Tables from the wizard, click Finish. Monday, May 9, 2011 10:50 PM. Jerry Weng Ctrip. Oct 24, 2017 I'm building a new application using Entity Framework 6 database first in Visual Studio 2017. At first, updating the.edmx from my database only took a matter of seconds, but recently (we now have around 50 tables) it has become painfully slow.

For more complex web applications it is good practice to separate the data access layer from the presentation layer. You can even reference the data access project from another solution if that also needs access to the same data.
