We have a solution of about 50 projects (mainly WPF and Class Libraries).
I have discovered, that Find all References on items, that are references almost in every XAML file freezes VS and takes too long.
It's about 30 seconds of lag while searching for about 400 symbol references.
During the lag, there is 'Looking for symbol in XAML files... Press Escape to cancel' status on the status bar.
There are about 120 XAML files in our solution and looking for Find All References on 'Model' in the code behind took about 30 seconds.
Our Model is the DataContext for our View and it derieves from the ViewModelBase. It also implements INotifyPropertyChanged.
Out Views (XAML files) have bindings to the Model.
ESC key during search doesn't work - it doesn't stops searching, VS is totaly frozen ('Visual Studio is busy' popup occurs)
After about 30 seconds there are about 400 results in the Find Symbol Results window.
