I have spent about a month doing whack-a-mole with bugs associated with snapins in MMC 3.0. On top of this, Microsoft has basically abandoned it. I haven't been able to get MMC 3.0 working with .NET 4.0 (developers have reported some workarounds, but none have worked for me). That's it, I had it!

Been working really hard on PainlessSVN, as I still use it to manage all my repositories. I've been trying to add a bunch of features that I want, as I despise managing Subversion with the command-line. MMC just keeps getting in my way.

I'm investigating moving PainlessSVN over to WPF, MVVM, and CSLA. CSLA is a business framework, and it has remote access baked in. It does a good job of hiding the complexities of WCF from the programmer.

This means that PainlessSVN 2.0 will not be released this year, and it will not be a MMC 3.0 snapin.
