Could not connect to the web server for page

Question

I am writing tests for helper classes in the app_code directory.  I am using Cassini.  Suddenly, I am getting the following error:

 

Could not connect to the web server for page 'http://localhost:6721/MReportsWeb'. The remote server returned an error: (500) Internal Server Error.. Check that the web server is running and visible on the network and that the page specified exists.

The following is one of the tests:

 

[TestMethod()]
[HostType("ASP.NET")]
[AspNetDevelopmentServerHost("%PathToWebRoot%\\MReportsWeb", "/MReportsWeb")]
[UrlToTest("http://localhost/MReportsWeb")]
public void SessionHelper_CurrBusinessProcess_Test()
{
    string val = "ICE";
    MReportsWebAppCodeTestProject.SessionHelperAccessor.CurrBusinessProcess = val;
    Assert.AreEqual(val,
        MReportsWebAppCodeTestProject.SessionHelperAccessor.CurrBusinessProcess,
        "SessionHelper.CurrBusinessProcess was not set correctly.");
}

This sets a value in Session and the reads it back.  This really was working.  Unfortunately the TestResults dir is empty.  Any suggestion?
