I want to copy godot 3.2 all source codes into VS2019 solution instead of using the generate proj file for reasons that I want to use the godot as the third party dll. Is there a solution created in VS2019 instead of using the NMake configuration?
Most Godot contributors don't use Visual Studio as their main IDE, so I don't think that exists.
What IDE is used by most godot contributors?
I don't know what most Godot contributors use, but I am using Visual Studio Code as my IDE. It works pretty well. I also use the terminal to start scons builds and to read debug print statements.
Qt Creator, Visual Studio Code and CLion are popular options among Godot contributors. See Configuring an IDE in the documentation.
