Just an FYI for anyone who encounters the same issue i did.
I wanted to use Telerik UI for .Net Core however in VS2019, only the MVC options were available.
I checked the Progress Installer, but the option to enable VS2019 support was disabled in the Progress Installer.
The info tooltip says: "Requires Microsoft Visual Studio 2019 with .net core cross-platform development workload"
So I reran the VS Installer, but I had already installed the .net core cross-platform workload previously.
After googling and finding nothing online, I tried the VS installer again. I checked individual components.
I saw that core 3 sdk wasn't selected. I added that and scrolled through the full list looking for anything that may have to do with the latest .net core framework and web development.
After that was done, the Progress Installer option to support VS 2019 was available.
So if you have a similar issue, check the individual components tab on the VS installer.
