Can you catch that exception and capture ex.ToString(), then post it here?

Also, what version of CSLA and what version of .NET an d what version of ASP.NET?

[jdchristian]

Sorry, I should have included that in the original post.
CSLA v5.1.0 (NuGet Packages)
.NET 4.7.2
If I understand how to read the ASP.NET version right, it is 4.0.30319.42000

Thanks!

Interesting. Version 5.1 includes code to wrap ClaimsPrincipal for serialization.

So now I'm wondering what type is your principal and your identity? The serializer is clearly hitting some principal type that contains a ClaimsIdentity, and so I'm thinking that the principal type is neither ClaimsPrincipal nor CslaClaimsPrincipal.

[jdchristian]

I have tried two methods with the same results. Initially, I used the PTIdentity and PTPricipal from ProjectTracker. I have also tried:

            var identity = NSERT.Library.Security.PTIdentity.GetPTIdentity("admin", "admin");
            var baseidentity = new ClaimsIdentity(identity.AuthenticationType);
            baseidentity.AddClaim(new Claim(ClaimTypes.Name, identity.Name));
            if (identity.Roles != null)
                foreach (var item in identity.Roles)
                    baseidentity.AddClaim(new Claim(ClaimTypes.Role, item));
            var principal = new System.Security.Claims.ClaimsPrincipal(baseidentity);
            Csla.ApplicationContext.User = principal;

It is likely my lack of understanding of how claims work, but I am lost right now.

Try looking at the BlazorCslaAuthentication sample from my Blazor book. It has the most current authentication model for modern ASP.NET and CSLA.

Specifically the code in the Login page

Will do! Thank you.
