Description

When creating a new MSTest test project in Visual Studio 2010 Beta 2, the project is always created to target .NET 4.0 even 3.5 is the target framework in the "New Project" dialog.

Also, when upgrading existing Visual Studio 2008 MSTest test projects to 2010 Beta 2, these projects are automatically upgraded to target .NET 4.0 without warning.

It looks like Visual Studio 2010 Service Pack 1 will resolve this once it is released (see the heading 'Better platform support | Unit Testing on .NET 3.5'):

You can get the Beta version with a Go-Live licence now...

At issue is that SharePoint does not currently support framework 4.0, Wily Tools does not support framework 4.0 and basically for any large company upgrading framework is a major thing. It's too bad that the super great work done by the rest of the VS2010 team was majorly sullied by the not so smart or even empathetic decision of the TestProject team.

Thanks, Microsoft! It would have been nice to know a year ago that your claims that VS2010 supports multi-targeting were lies shrouded in marketing spin! Giving customers the choice of staying on VS2008 or switching off of MSTest sounds like a lose-lose for Microsoft and their customers. If it was any company other than Microsoft, I would find it hard to believe that the person who suggested this ridiculous "feature" wasn't fired on the spot!

Confirming that this issue is present in the RTM version of VS 2010. See also: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=483891

Visual Studio Product Team, I suggest you fix this as soon as you are able.

This has to be fixed ASAP. What is the point of multitargeting of not all projects are able to run on the same version??

Nobody's going to be interested in Microsoft's "pain" when it comes to not supporting multi-targeting on test projects.

The stark reality is that this decision effectively rules out upgrading to VS2010 for many shops. A lot of people will be deeply uncomfortable with running their unit tests in a different version of the .NET Framework than they are actually running in their product. As far as testing goes, that's 100% unacceptable.

Don't wait 18 months to address this. Get it fixed now.

This is a huge problem! We have to stay with .NET 3.5 because we use state-machine workflows in WF. And for reasons that still don't make sense to me WF4 dropped state-machine workflows. So our projects which use both s-m WF3.5 and Unit Tests are not upgradeable to VS2010. What is the point of even including multi-targeting in VS2010 if the Unit Tests aren't multi-targetable?!? Sincerely hoping you release a patch for this.

Hi Chris,

In VS 2010, the Test Team has made a painful yet concious decision to not support multi-targeting. As a result, test projects will be upgraded to target .NET 4.0. We have made some, workarounds to allow a VB Test Project that references an MVC code under test to not upgrade, but in general, all others will be retargeted. The VB 3.5 Test Project sill has some limitations and will always run tests in a .NET 4.0 process. Also, you cannot take the tests and run them on a VS 2008 test system.

Thanks
Visual Studio Product Team.
