TestDriven.Net doesn't find tests

Question

I have a test project using MbUnit and TestDriven.Net.

If I right-click on an individual test method and say "Run Tests" the test runs successfully. Same thing if I click on a file name in the solution explorer.

However, if I right click and say run tests on the project or the solution, TestDriven.Net reports "0 Passed, 0 Failed, 0 Skipped."

I have other similar projects that work just fine, and yes, the classes are labeled [TestFixture] and the methods are labeled [Test].

Answer 1

Are the classes public?
