Using Microsoft.AspNetCore.All package in netstandard

Question

At the moment I\'m porting an asp web api to .Net Core.

The api uses a Class library which provides some implementations of the ActionFilterAttribute class.

Answer 1

You can't (well technically you could via NuGet Fallback, but you shouldn't as it may affect your portability) and you shouldn't.

The .All package is a convenience meta-package, so you don't need to reference a dozen or other assemblies for even the simplest ASP.NET Core Project.

It's targeting .NET Core for a reason, so you can't use it in .NET Standard.

When you publish your application, the unused packages will be stripped off. When doing a class library you don't want dependency on everything but only the packages which are required by your project.
