Getting an exception every time a tizen project is loaded into Visual Studo
Getting an exception every time a tizen project is loaded into Visual Studo
BY 29 Apr 2020Tizen .NET
This problem wasn’t there from the very beginning. It looks like it started happening after one of the latest Visual Studio updates. I have Visual Studio 2019 16.5.4 now. The exception is marked as a recoverable but apparently something is wrong anyway. I tried to uninstall and then install Visual Studio Tools for Tizen back but that didn’t help. Can anybody from Tizen team look into it?
