Assembly installed in GAC First

    Question

  •  

    I was working on a project when .NET Framework 3.5 SP1 was released. I installed the SP on the machine I was using to develop the project. Since then any new builds that I have created give an error when I try to install/run the application:

     

    Unable to install or run the application. The application requires that assembly System.data.entity version 3.5.0.0 be installed in the Global Assembly Cache (GAC) first. Please contact your administrator.

     

    I have tried requiring both .NET Framework 3.5 and .NET Framework 3.5 SP1 in the publishing options, recently I added the reference to System.Data.Entity to the project and specified it as...Copy Local True. I still cannot install the project. I am getting this error on multiple computers runing Windows XP (SP2 and SP3). I have not had a chance to install it on Windows Vista.
