We can download several workloads (which are parts of FCL) from Visual Studio Installer such as "Data storage and processing". But we can also download EntityFramework.Core Package from NuGet Package Manager and work with it and connect to DB properly. In that case why we need to download workloads from VS Installer? Are they just for templates or what?
I have searched about it and found that options that we can download from VS Installer are parts of FCL. But for example, if we can connect to the DB and use it through downloading "EntityFramework.Core" Package from NuGet Package Manager, why we need to install "Data storage and processing "from VS Installer?
