I feel like a) I should know the answer already and b) this would be a common question, but I can't find the answer.
I want to use Microsoft.AspNetCore.Http.HttpRequest in a .NET Standard 2.0 class library project. Ok, I guessed I might need the Microsoft.AspNetCore package, but no that class isn't in any assembly in there apparently.
I can go on MSDN and see that the HttpRequest class is in
Namespace:
Microsoft.AspNetCore.Http
Assembly:
Microsoft.AspNetCore.Http.Abstractions.dll
So how do I find the package that holds Microsoft.AspNetCore.Http.Abstractions.dll?
I'm asking for the methodology, not just the package.
