Unit Test/Code Coverage Warning & Error VS2010

I have a sample test project given to developers on my project team to learn how to use automated tests. When I run the set of unit tests that I have, they all pass but I receive the following Warning and Error:

Warning: conflict during test run deployment: deployment item '[...]\WebAppMvc4.dll' directly or indirectly referenced by the test container '[...]\webappmvc4.tests.dll' cannot be deployed to 'WebAppMvc4.dll' because otherwise the file '[...]\WebAppMvc4.dll' would overwrite deployment item '[...]\WebAppMvc4.dll' directly or indirectly referenced by '[...]\webappmvc4.tests.dll'

Error: Cannot initialize the ASP.NET project 'WebAppMvc4'. Exception was thrown: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting 'http://localhost:12903/VSEnterpriseHelper.axd' returned an error: The remote server returned an error: (500) Internal Server Error.

This is very similar to the problem found here: Test run errors with MSTest in VS2010

However, the resolution to this problem had to do with turning off the Sign The Assembly checkbox in the project properties. Signing is not turned on for this project, and I have not been able to determine the reason for the Warning/Error.

Here is the information from Event Viewer for the Warning:
