  • 0

I have a problem with configuring an EDMX file that lives in an other assembly than by web project. My project looks somewhat like this:

Project 1
--> Database.edmx
--> App.Config

Project 2
--> Ton's of .cs and .aspx files.
--> Web.Config with the proper connection string.

Inside Visual Studio the updating of the .EDMX file inside Project 1 goes smoothly and while I had the .EDMX file inside project 2 the application ran as it supposed to.

Anyone has an idea on how to configure the .EDMX file inside Project 1 to point to the connectionstring of Web.Config? (or should I use Project1.dll.config to configure Project 1?)

    You have to change the * in the connection string for the assembly name where the .edmx files are in:

    <add name="Entities" connectionString="metadata=res://*/Models.EF.Model.csdl|res://*/Models.EF.Model.ssdl|res://*/Models.EF.Model.msl;provider=System.Data.SqlClient;provider connection ... ;" providerName="System.Data.EntityClient" />

    for

    <add name="Entities" connectionString="metadata=res://Project2/Models.EF.Model.csdl|res://Project2/Models.EF.Model.ssdl|res://Project2/Models.EF.Model.msl;provider=System.Data.SqlClient;provider connection ... ;" providerName="System.Data.EntityClient" />
