.NET Core RuntimeIdentifier vs TargetFramework

Question

Can someone explain the purpose of this two in csproj file (VS2017):

netstandard1.6
win7&         


        

Answer 1

RID is short for Runtime IDentifier. RIDs are used to identify target operating systems where an application or asset (that is, assembly) will run. They look like this: "ubuntu.14.04-x64", "win7-x64", "osx.10.11-x64". For the packages with native dependencies, it will designate on which platforms the package can be restored.

First change to proper RID from win7 to win7-x64 or win7-x86. Next add other RID like ubuntu. For example:

    netstandard1.6
    win7-x64;ubuntu.16.10-x64

Target framework looking good. For more read docs
