I have downloaded the following zip. http://www.palmmedia.de/Blog/Download/f0f3664d-3199-4095-bb15-815cf9f3ef2e
I did update the MVCSitemap packige in the website project by NUGET. After that I get a lot of errors (88) generated by my t4 template. Can't find a way to fix this.
When not updating this packige everything works as expected and I can build the project. Somehow I can't edit a thing in my project without getting this big load of errors.
