I am following this guide to installing and using MSpec, but at the step where he runs MSpec for the first time, I get the following error:

Could not load file or assembly 'file:///[...]\Nehemiah\Nehemiah.Specs\bin\Debug\Nehemiah.Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

I have - to my knowledge - done everything more or less exactly like he did up to this step, except where differences arise because he's using VS2008 and I'm using VS2010, and everything has worked so far. The project Nehemijah.Specs (and the entire solution) builds without problem, both in Visual Studio and on my build server, and I can't find anything useful in Event Viewer (although I might not be looking in the right place here...)

What to do?

My team is attempting to use mspec without nunit on a new ASP.NET MVC2 project. We're not at the spec-writing… >>> More

When using a mocking framework and MSPEC where do you set your stubs

I am relatively new to using MSpec and as I write more and more tests it becomes obvious to reduce duplication you often have to use a base class for your setup as per Rob Conery's article I am happy with using the AssertWasCalled method to verify my expectations, but where do you set up a stub's… >>> More
