Hi there!
I migrated a little game project of mine from MonoGame 3.5 (VS 2015) to 3.6.0.1625 (VS 2017) on Windows Desktop.
The only change I did is to make sure that the HiDef graphics profile is set in the constructor of Game as suggested here: [SOLVED] Does the HiDef profile work correctly in MonoGame 3.6?
I made sure that (/profile:HiDef) is set in the mgcb file.
Unfortunately now I get an InvalidOperationException and the stacktrace (see below) does not refer to any code of mine directly, so I have no idea where to start looking. I do not use any threading.
Made sure that the render target is set to null at the end of the Draw method as indicated here: http://what-when-how.com/xna-game-studio-4-0-programmingdeveloping-for-windows-phone-7-and-xbox-360/render-targets-xna-game-studio-4-0-programming/
The code is still running fine with MonoGame 3.5.
Thanks for your help - Andreas
