How do I avoid ServerAuthenticationStateProvider.SetAuthenticationState() throwing an exception

[DavidThielen]

Hi all;
I have written my own AuthenticationStateProvider to add two bits of functionality:

1. I added IdentityUser.Enabled and return an anonymous user ClaimsPrincipal if disabled.
2. It will re-read the claims every 25 minutes.

Bare minimum of the code:

public class ExAuthenticationStateProvider : ServerAuthenticationStateProvider
{
    public override async Task<AuthenticationState> GetAuthenticationStateAsync()
    {
        // the ToList() is to make a copy of the claims so we can read the existing ones and then remove from claimsIdentity
        var claimsIdentity = new ClaimsIdentity(authState.User.Identity);
        foreach (var claim in claimsIdentity.Claims.ToList()
            .Where(claim => AuthorizeRules.AllClaimTypes.Contains(claim.Type)))claimsIdentity.RemoveClaim(claim);
        foreach (var databaseClaim in listDatabaseClaims)
            if (databaseClaim is { ClaimType: not null, ClaimValue: not null })
                claimsIdentity.AddClaim(new Claim(databaseClaim.ClaimType, databaseClaim.ClaimValue));

        // set this as the authentication state
        var claimsPrincipal = new ClaimsPrincipal(claimsIdentity);
        authState = new AuthenticationState(claimsPrincipal);
        SetAuthenticationState(Task.FromResult(authState));
    }
}

When I call SetAuthenticationState() I get:

Error 15:18:00.014 [JASMINE]-[] LouisHowe.web.Services.ExAuthenticationStateProvider - GetAuthenticationStateAsync() exception: Cannot access a disposed object.

What's going on and how do I notify the Identity Library of this change?
