So what have you selected? Just .NET desktop development? Or is anything else needed?
If I select a full Installation of VS 2017 Community it is about 50GB and that is too much for my SSD (my IntelliJ Ultimate Java IDE from Jetrains is less than 1.2 GB) :
Oof - it was long enough ago that I honestly don’t recall exactly what I selected, but according the VS Help->About this is what I’ve got installed:
Visual Basic 2017
Visual C# 2017
ASP.NET Template Engine 2017
Common Azure Tools
NuGet Package manager
Visual Studio Code Debug Adapter Host Package
I’m pretty sure all I asked for was C# so the rest must have just been included automatically,
