I've upgraded my project to the latest release of System.IdentityModel.Tokens.Jwt (5.0.0).

Now I get a runtime exception in my host:

Could not load type 'System.IdentityModel.Tokens.TokenValidationParameters' from assembly
'System.IdentityModel.Tokens.Jwt, Version=, Culture=neutral,
( others at IdentityServer/IdentityServer3#3017 saw the same with JWT breaking change)

Run the below command on Package Manager Console for both Projects (TodoSPA & ToGoAPI)

Install-Package System.IdentityModel.Tokens.Jwt -Version

Then build, select root Solution TodoSPA, and press F5 to start both websites and run the solution. Should work OK now.

I recorded a video on the install steps on my blog.
