Exception in ConfigureDPoP when using System.IdentityModel.Tokens.Jwt 8.0.2

[kurtcodemander]

Calling the ConfigureDPoP method on OidcClientOptions when using System.IdentityModel.Tokens.Jwt 8.0.2 throws the following exception:

{"Attempt by method 'IdentityModel.OidcClient.DPoP.DPoPProofTokenFactory..ctor(System.String)' to access method 'Microsoft.IdentityModel.Tokens.CollectionUtilities.IsNullOrEmpty<System.Char>(System.Collections.Generic.IEnumerable`1)' failed."}

After cloning this repo, upgrading to System.IdentityModel.Tokens.Jwt 8.0.2 and .net 8, there's a compilation error in the constructor of DPoPProofTokenFactory on this line:

if (_jwk.Alg.IsNullOrEmpty())

Changing it to if (string.IsNullOrEmpty(_jwk.Alg)) fixed the problem for me.

Maybe a contributor with better knowledge of this repo could look into it and fix it properly?

+1 - I'm seeing this too.
