Hi,
As the name of this post suggests, I was experiencing af LoaderException after upgrading from 9.8.8 to 9.9.6.
I solved it by manually removing the reference to Microsoft.IdentityModel.Protocol.Extensions in packages.config (and .csproj).
Can this reference be removed before the next release? It is only a problem for the Nuget version, the zip is fine.
Best regards,
