Visual Studio 2010 Rebuild All then run unit tests builds all again

Question

In Visual Studio 2010 I do the following:

• Build > Rebuild Solutuion.

  No errors, no warnings.

• Solution > Run StyleCop (Rescan All)

  No errors, no warnings.

• Test > Run > All tests in solution.

  A build kicks off again - why is this? Is there a way around it?

Answer 1

Well as no-one has answered I will offer my workaround.

Make changes, then run the tests without building first. This will obviously do a build, but 1 only.
