Visual Studio has been a 32-bit process (`devenv.exe`) for 20 years. This meant it was capped at 4GB of RAM, regardless of your machine specs. VS 2022 is finally 64-bit.
Why it matters
I opened a massive solution with 1,600 projects (Orchard Core). In VS 2019, it would crash with OOM (Out Of Memory). In VS 2022, it consumes 8GB of RAM but stays fluid. IntelliSense is instant.
Hot Reload is the other major feature. You can change C# code (even lambda expressions) while the app is running and see the changes instantly, without a recompile. It works for WPF, WinForms, and ASP.NET Core.
