title: Unable to set TestContext property
body: <p>I have a visual studio 2008 Unit test and I'm getting the following runtime error:</p>
  
  <pre><code>Unable to set TestContext property for the class JMPS.PlannerSuite.DataServices.MyUnitTest.  Error:  System.ArgumentException:  Object of type 'Microsoft.VisualStudio.TestTools.TestTypes.Unit.UnitTestAdapterContext' cannot be converted to type 'Microsoft.VisualStudio.TestTools.UnitTesting.TestContext'
  </code></pre>
  
  <p>I have read that VS 2008 does not properly  update the references to the UnitTestFramework when converting 2005 projects.  My unit test was created in 2008 but it inherits from a base class built in VS 2005.  Is this where my problem is coming from?  Does my base class have to be rebuilt in 2008?  I would rather not do this as it will affect other projects.</p>
  
  <p>In other derived unit tests built in 2005, all that we needed to do was comment out the TestContext property in the derived unit test.  I have tried this in the VS 2008 unit test with no luck.  I have also tried to "new" the TestContext property which gives me a different runtime error.</p>
  
  <p>Any ideas?</p>
