Dunno, time to check your plugins slowing down the IDE.
Better not having Resharper around.
I have zero plugins installed. VS is just so slow that it's even outmatched by a javascript/Electron app like vscode.
Then it is definitely a "my computer/your computer" problem.
My computer has a PCIe 5 SSD, Ryzen 7950 and 128GB Ram. This is solely a VS problem, as you can see from the other posters with the same issue. And from the fact that vscode displays results instantly. It's only ever VS that's slow, accross any system I've ever used it with.
