I'm am noticing when using VS2010 and running MSTest unit test that there is a major lag/delay when using in conjunction with the Enterprise Library. Specifically when registering the EnterpriseLIbraryCoreExtensions. The below code is just to show you the delay. When stepping through in debug, the JustCode test runner will sit for close to 2 minutes when executing AddNewExtension. This behavior is not seen when running the same test in VS2012 using JustCode and the test runner.
public void TestMethod1()
var container = new UnityContainer();
There is no delay in running this same test through the built in MSTest runner within VS2010.
