Hi Everyone,

I'm a big fan of MSpec so naturally I wanted to use is right away with VS2010 as well. I have the MSpec runner defined as an external tool in Visual Studio to be able to have it always visible as a toolbar item.

Anyway, whenever I try to use the MSpec runner (mspec.exe) with a .NET 4.0 solution I get the following error:

Could not load file or assembly 'file:///C:\Users\[SOMEUSER]\[SOME_FOLDERS}\bin\Debug\[PROJECT].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 can still run my specs with the Resharper 5 runner so it's no big drama, but I bothers me to no end :þ

Do you guys have any idea what the problem could be? Is there any solution other than recompiling the whole Mspec source code as a .NET 4.0 solution, which I really, really don't want to do?

Thanks in advance.
Sergi

Is mspec better with or without nunit?

I've seen mspec used with nunit on some blogs and discussions. In fact, most of the examples on the web that I've seen demonstrate mspec with some kind of nunit dependancy or integration.

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
