Building coded ui test project fails when "Perform runtime contract checking" is set to "full"

I have a simple Test project where a CodedUITestMethod is created. The test method simply clicks the Windows Start button in the taskbar. The method is generated by the Coded UI Test Buil开发者_如何学Goder tool from Visual Studio 2010 Ultimate.

Then, I go to project's Properties page, Code Contracts tab. Check the Perform Runtime Contract Checking check box. Change the value of Contract Reference Assembly combo box to "Build".

Now I hit F6 to build the project and receive the 2 errors: Reading assembly 'Microsoft.VisualStudio.TestTools.UITesting' resulted in errors.

C:\Program Files (x86)\Microsoft\Contracts\MsBuild\v4.0\Microsoft.CodeContracts.targets (240,5): error MSB3073: The command ""C:\Program Files (x86)\Microsoft\Contracts\Bin\ ccrewrite" "@CodedUITest_Contract2ccrewrite.rsp"" exited with code -1.

I have uploaded my project zip file to my codeplex project

Could someone download the project and see if they can reproduce the compile error? Thanks.

The problem is solved. It appears that Microsoft.VisualStudio.TestTools.UITesting.dll references another dll that is not added into the project.

Add Microsoft.VisualStudio.TestTools.UITest.Playback.dll in the folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\ solves the issue.

Thanks to David K Allen who answered the question on the msdn forum.
