I'm trying to use LINQPad 4 (the latest beta) with Entity Framework POCO classes. I take the normal path of creating a new connection and then selecting "Entity Framework DbContext POCO(4.1) and then selecting my he assembly holding my classes. When I do so I get the following message
"Could not load file or assembly EntityFramework. Version=4.1.O.O, Culture= neutral, PublicKeyToken=b77a5c561934e089 or one of its dependencies.
The system cannot find the file specified."
I'm able to load the assembly from my application just fine. What gives? It seems a bit different from the previous problem like this reported in the CTP.
I had the same problem today, this is how I solved it:
Apparently the LINQPad 4.36.3 requires in some way Entity Framework 4.2 :/
It was released last week: ADO.NET blog
What I did is:
- Installed EF4.2 via NuGet
- Rebuilt the project
- Copied all my project .dll files to LINQPad folder (including the 4.2 EF.dll)
- I read here that I need to add something to the LINQPad.exe.config file but it was already there..
[At this point I tried removing that assembly redirect and ran it against my 4.1 dll, did not work, was still looking for 4.2] - Closed VS and uninstalled EF4.1
Thats it, after that both my project is now running on 4.2 and LINQPad works as well.
