Due to the overwhelming request by the community, we have received thousands of e-mails from .NET developers, that almost crashed our servers. And after we have had serious discussions with a large software company, we have managed to find a way that will allow us to open source Typemock Isolator for the benefit of the community (and of myself 😉
It will take us some time to clean the code, but in the meantime we have uploaded the sources to codeplex, you can download them here.
