I've used NUnit for years and I wanted to try XUnit. So I installed XUnit and ran the executable that allowed you to run XUnit via TD.net.
I can't seem to run more than one test at a time. With NUnit + TD.net, I could click on the filename in the solution and run all the tests in the file. I can't seem to do that with XUnit + TD.net.
Is this something I can do?
Make sure you run the installer that comes with XUnit.net. There is a button to click that will install the TestDriven.net support.
The problem you are having is described here: http://www.codeplex.com/xunit/Wiki/View.aspx?title=FaqTestDrivenNet&referringTitle=Home
