title: "Exception has been thrown by the target of an invocation" Running Tests - VS2008 SP1
body: <p>I'm using Visual Studio 2008 Team Suite and I'm unable to run tests and display the Test/Windows/Test Result Window.<br>
  The result is a dialog box with the following content : "Exception has been thrown by the target of an invocation".<br>
  Team Explorer has been installed after Visual Studio 2008 SP1. So I have re-apllied the service pack.  </p>
  
  <p>Searching the web I found that this error is pretty common but unfortunately, the proposed solutions does not work for me. The problem was never analysed so I decided to give it a try : I reproduced the problem on a computer, attached the process with windbg and start with the basic investigations. </p>
  
  <p>Following are the first results :</p>

  <p>In order to be able to continue the analysis, we need to get the parameters to see what is going on.</p>
  
  <p>I also tried to run devenv.exe with the /log switch. No error in the log after reproducing the problem.</p>
  
  <p>Finally, If Team Explorer is removed from the system, the problem goes away.</p>
  
  <p>Any help appreciated.</p>
