How to: Validate an .edmx File Model
The Entity Designer enables you to validate an .edmx file. When you validate an .edmx file with the Entity Designer, any validation errors that occur will be shown in the Error List. Note that validation errors are not fatal errors; a project will build successfully even when the file has validation errors.
|You can also validate an .edmx file from the command line by using the EdmGen.exe tool. For more information, see EDM Generator (EdmGen.exe).|
To validate an .edmx file
Open the .edmx file in Visual Studio.
Save the .edmx file with it open in Visual Studio.
Build the project that includes the .edmx file.
Note: The Validate on Build property of the .edmx file must be set to true for the project to be validated upon building the project.
