The code analysis gets corrupted when viewing XAML files after a time. I have attached two files. The first shows what the window looks like when the analysis goes awry. The other shows the window after I go to the AddIn dialog, turn ReSharper off and then back on.
I'm using the January 16th nightly build but this bug has been around for a very long time.
By the way, in the second image you will see that it is flagging x:Name as invalid. This bug has been around since Resharper first introduced XAML support. Is this ever going to get fixed?
This analysis bug makes working on XAML extremely annoying. I end up having to turn off code analysis because the suggestion dialogs for namespaces get in the way.
