I'm using Visual Studio 2012 Express for Windows Phone to follow this XNA course. The course is intended for XNA in Visual Studio 2010, but the professor said most people wouldn't have any problem in running other IDE configurations.
The project needs a custom library provided by the professor (ExplodingTeddies.dll). When running the project after adding this library to the references, I get the following error:
The primary reference "ExplodingTeddies" could not be resolved because it has an indirect dependency on the framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "ExplodingTeddies" or retarget your application to a framework version which contains "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".
I don't know if it's because I'm using an Express edition or if it's because this is a XNA for Windows Phone project, but I can't retarget the application framework to any other option, so that's currently out of question.
Is there anything I can do, or do I have to wait for Dr. T to provide a modified library to use in VS 2012 Express?
