SourceTree crashing on startup

Question

All of a sudden SourceTree is crashing on startup. It worked fine a couple of days ago but now in the logs I'm getting the message "System.Windows.Markup.XamlParseException: Provide value on 'System.Windows.StaticResourceExtension' threw an exception. ---> System.MissingMethodException: Method not found: 'System.Uri System.Xaml.XamlObjectWriterSettings.get_SourceBamlUri()'."

Reinstalling, reverting to an older version and repairing .NET did not help. I'm using Windows 7.

Anyone else come across this?

Thanks, but that didn't work unfortunately.

Seems like in the last few days Source Tree is having problems with its dlls in this thread https://answers.atlassian.com/questions/32972886 an error is described which is related to missing functions. Perhaps the same solution will work for you as well. Look for the answer from Todd Dowty
