I've been looking for a way to do app.config transformations. I have found SlowCheetah, but it looks like SlowCheetah does not support VS 2008. Is there any plugin equivalent of SlowCheetah for VS 2008?
The XDT transforms, which SlowCheetah relies on, requires .NET 4.0. Since .NET 4.0 was after VS2008 we cannot really add support for VS2008. Also I think the extensibility model in VS2010 was a big change from VS2008.
