Visual Studio 2022 will be 64-bit 

“Visual Studio 2022 will be a 64-bit application, no longer limited to ~4gb of memory in the main devenv.exe process,” said Amanda Silver, a program management exec in the Developer Division in an April 19 blog post introducing VS 2022. “With a 64-bit Visual Studio on Windows, you can open, edit, run, and debug even the biggest and most complex solutions without running out of memory.”
