How can I change a .NET standard library to a .NET framework library? : <p>I'm writing a class library for a simple parser in C#. When I first created it, I used .NET standard 2.0, but now I need to migrate it to .NET 4.6 both to conform to the other projects in my solution and in order to use NUnit.</p>

<p>I tried to follow the instructions <a href="https://docs.microsoft.com/en-us/visualstudio/ide/how-to-target-a-version-of-the-dotnet-framework" rel="noreferrer">in the Microsoft documentation</a>, but when I try to select another framework in the properties, I can only find other .NET standard versions.</p>

<p>How can I migrate it? Will I need to manually edit the <code>.csproj</code> file?</p>
