问题

I have created a setup project and installed on local machine. The application opens but connection to Database doesnt occurs it throws error as following screen shot. I am using Entity Framework 4.0 but it asks for EntityFramework 4.4.0 don't know why? i have built this setup with framework 4.0 default with some devexpress & telerik tools in project.

NOTE: Their is no reference to Entity 4.4 but still it asks for 4.4 any idea? but reference to 4.0 is their in config file.

回答1:

It sounds like you have somehow managed to lose the EF reference, perhaps by accidentally adding the .net 4.5 version of the assembly.

The easiest way to resolve this is to go into nuget and uninstall EF 5 and then reinstall it. This will get nuget to readd it to your solution and set up the project reference correctly.
