I've recently upgraded my visual studio from 2010 to 2015, and since them, I'm getting a lot of warnings in my output window like:

It happens every time a value in the gridview is changed.

It affects the performance of visual studio, since the output window is very busy. 

Why it happens? It is something you are doing wrong and can be fixed?

Can I disable these warnings somehow?

 

Thanks.

Hi,

These warning messages should not be related to any new changes in our code. There is a setting in VisualStudio for that particular set of warnings. You can open Tools > Options > Debugging > Output Windows > WPF Trace Settings > Freezables and set the desired value.
