Now we are using visual studio 2019 for our project development.
Now which version of .net core(.NET Core 3.1 or .NET 5.0 .NET 6) i need to install to convert my .net framework 4.7 project to the .net core project?

Yes, I want balloon tooltip to be displayed only in the upper right corner always(static place).
I want the style of balloon tool tip to be same as there in my screenshot.

Then we should use below template for project development right?
