I need to upgrade the VS2015 version to VS2019. I have VS2015 and VS2019 installed on my PC. When I build my project using VS2015, everything run fine and able to view the GUI. The same project when I open as VS2019, the reference was missing. But it can still build successfully without error.
Solution tried not working:
1.) Open and close VS2019. Reopen it still same.
2.) Reinstall VS2019
3.) Add reference, but the reference page is blank.
VS2019 Add reference but empty choice
My goal is able to view the GUI in VS2019. Anyone have solution for this? Appreciate if can help me.
VS2015 Reference Correct Behavior
VS2019 Reference Missing
Design View not able to use due to missing reference
Thanks!
