Visual Studio freezes after changes to the XAML file

I recently got into a weird problem, it seems like this happened by accident.

When I make changes to the XAML file (it can be anything, change the text with a button, change the background color, etc.), my visual studio freezes when my program starts up.

Does anyone know how to fix this really annoying problem?

I also posted a thread about this on the MSDN forum, and got a response that did the trick:

Obviously, I had to delete the Project Solution file and then run the .csproj file.

I don’t know why, but it made him work again! Therefore, if someone has encountered this problem, try the solution above.

I had the same problem and for me this caused Resharper . Try pausing Resharper and removing all third-party add-ons if that doesn't help (resharper, ghostdoc, etc.).

Also try starting VS with the / SafeMode flag and see if it works properly.

The advice from this page that helped me in my case ...

Disabling the effects display (fx button in the lower left corner of the xaml editor) caused a significant increase in performance.

Also, deleting a .suo file .suo sometimes fix many Visual Studio problems. In VS2015, simply delete the .vs folder in the root of the solution where the .suo file .suo .

In my case, I deleted all the generated files along with the .db and .opendb files, and the xaml editing stopped to hang up.

This is an old question, I know, but since others have similar problems in older and newer versions of Visual Studio, maybe the following workaround may occur (tested on three PCs, VS 2017, Windows 10):

  • Open a XAML project in Visual Studio
  • Open Windows Task Manager
  • Search Microsoft Visual Studio XAML Designer (if not, try opening the XAML file in VS)
  • Right click and select Properties
  • Select the Compatibility tab.
  • Below compatibility mode check Run this program in compatibility mode for:
  • Choose Windows 7

I have not had any crashes / hangs since the compatibility settings were changed.

Good luck

I got the same problem. VS2015 will either freeze for about 40 seconds, or sometimes crash when closing the XAML constructor. After removing the CodeMaid extension , the problem disappeared.

I tried another project that I had, and I could open XAML and run my project.

Therefore, I decided that this was not a visual studio, but my real project.

Removing bin , obj and vs from each project worked for me.

Then open again, rebuild, and now I can open XAML again and start the project normally.
