Code Coverage configuration using Test Settings is deprecated

If you used a .testsettings file in Visual Studio 2010, then it will still work in the current edition of Visual Studio. Code coverage analysis and other testing functions will be performed using the framework from Visual Studio 2010. However, we recommend that you remove the .testsettings file to take advantage of the enhanced testing features.

To configure code coverage, use a .runsettings file.
