Hi zhao790,
zhao790
but find a lot of exceptions shown on Output windows and Show Diagnostic tool. What is wrong with VS 2019 and how to fix them?
When you migrate your visual studio 2015 project to visual studio 2019, support for some project types changes over time.
Since we don't have your code, I suggest you can modify your code based on Exception thrown.
Or you can post your error message, then I will provide some useful suggestions.
Here a article about Project migration and upgrade reference for Visual Studio for you as a reference.
