I have a portable class library project targeting .NET Framework 4.5, and am trying to install System.Reactive.Interfaces to this project.
The dependencies for System.Reactive.Interfaces are NETStandard.Library for a .NETStandard project, but no dependencies for a .NET Framework project. Therefore this project should install Reactive.Interfaces without needing to install any other packages. My project also has a packages.config file, and no project.json or project.lock.json files exist in the solution.
However, attempting to install Reactive.Interfaces prompts me to install all of the System.* packages needed for .NET Core, as well as NETStandard.Library 1.6.0. How can I convince Nuget that this is a PCL for .NET Framework 4.5 instead of a .NET Standard project?
.Net Standrd is like "new" PCL but more complex. Change PCL to .Net Standard Library (if you want still use .Net Framework 4.5 you need to use .NET Standard 1.1). For more information i recommend this docs
