VS2010 upgrade with UnitTestFramework

Question

I am having an issue with upgrading from VS2008 to VS2010 and staying with .Net 3.5.

All my unit test projects as soon as I open them in VS2010 have their assembly references replaced from v9 to v10. This causes the build to fail because my projects are built in .Net 3.5.

<Reference Include="Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">

Replaced with:

<Reference Include="Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">

In order to fix this, I have to manually edit the assembly reference to point to V9 every time I open the solution.

Has anyone had this issue ? Any solutions ?

This is an issue with VS2010. If you go into your unit test project properties, the target framework dropdown will only have one choice: .Net 4

This was fixed with SP1. If you install SP1 and go into project properties you should be able to target .Net 3.5 with your unit test project.
