MSTest setting Apartment Threading to MTA

I'm using MSTest in Visual Studio 2010 on a project that needs the apartment thread开发者_C百科ing model set to MTA.

I've looked online and the items I've found and tried seem to only work with Visual Studio 2008 and 2005, see http://blogs.msdn.com/b/ploeh/archive/2007/10/21/runningmstestinanmta.aspx.

Thanks

You're right, most of the information online is out of date.

I eventually found Microsoft's documentation: How to: Run Unit Tests in MTA mode

You need to open your .testsettings file in an XML editor and add the following:

<TestSettings>
  <Execution>
    <!-- ... -->
    <ExecutionThread apartmentState="MTA" />
  </Execution>
</TestSettings>

Then restart Visual Studio. This worked for me.
