JwtSecurityToken moved to a new namespace. How to I leverage it in new projects?

Question

This Azure Mobile Apps library returns a JWT that is located in the following file:

Assembly System.IdentityModel.Tokens.Jwt, Version=4.0.20622.1351, Culture=neutral, PublicKeyToken=31bf3856ad364e35

When I inspect the JwtSecurityToken, I get this:

public class JwtSecurityToken : System.IdentityModel.Tokens.SecurityToken
   Member of System.IdentityModel.Tokens
   Version: 4.0.20622.1351

However I can only locate this comparable replacement in a newer DLL (version 5.1.0.0 of System.IdentityModel.Tokens.Jwt)

public class JwtSecurityToken :  Microsoft.IdentityModel.Tokens.SecurityToken
   Member of System.IdentityModel.Tokens.Jwt

Question

How am I supposed to use the linked library that seems to require the old assembly, but the only option available to me is in the new assembly and with a new name?

Answer 1

The System.IdentityModel.Tokens.Jwt v5.x libraries are for .NET Core. Azure Mobile Apps uses .NET Framework 4.x, so it requires the older libraries.

Install Microsoft.Azure.Mobile.Server - it will require the right version as a dependency.
