>>If i install the .NET Framework 4.8 Runtime on that computer, do i still need to install the .NET Framework 4.8 Developer Pack as well?
Yes.
The runtime type version is a lighter version, meant to run applications on servers. This runtime version doesn't have the information/extensions that Visual Studio needs, so if you are a developer who need to develop .net framework applications using Visual
studio, install both of them.
