This article raised some concerns about the migration path from .Net 4.0 to .Net 4.5 (Beta).
Will installing .Net 4.5 Beta cause problem when distributing .Net 4.0 builds from the same machine or is 4.5 properly isolated from 4.0?

No, it’s not isolated – it basically installs on top. I wouldn’t say it will necessarily break your builds – but there’s no guarantee that it won’t change your builds. In particular, I don’t know of any way to get back to the “stock” v4 C# compiler.
I personally wouldn’t recommend installing it directly on any machine where you really care about the builds. Go for a VM instead.
