How to determine if .NET Core Runtime is installed from CentOs 7

Question

One knows how to check if the .net core SDK is installed or not (you need dotnet --version or where dotnet). How about .net core runtime as well as the aspnet core runtime?

PS: since in production we don't need the .net Core SDK

Answer 1

dotnet --info will show the version of the SDK (if installed), the names and versions of all the runtimes that are installed, including the .NET Core runtime and ASP.NET Core runtime.

$ dotnet --info
.NET Core SDK (reflecting any global.json):
 Version:   2.1.301
 Commit:    59524873d6

Runtime Environment:
 OS Name:     fedora
 OS Version:  28
 OS Platform: Linux
 RID:         fedora.28-x64
 Base Path:   /usr/lib64/dotnet/sdk/2.1.301/

Host (useful for support):
  Version: 2.1.1
  Commit:  N/A

.NET Core SDKs installed:
  2.1.202 [/usr/lib64/dotnet/sdk]
  2.1.301 [/usr/lib64/dotnet/sdk]

.NET Core runtimes installed:
  Microsoft.NETCore.App 2.0.9 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
  Microsoft.NETCore.App 2.1.1 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

If you only care about the runtime (.NET Core and ASP.NET Core) versions, you can use dotnet --list-runtimes. This requires a recent-enough version of .NET Core:

$ dotnet --list-runtimes
Microsoft.NETCore.App 2.0.9 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.1 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]

I don't have the ASP.NET Core runtime packages installed, so it only shows me the .NET Core runtime.
