GetCurrentUserId

Reads the caller's public identifier from a ClaimsPrincipal, checking the userId claim first and falling back to ClaimTypes.NameIdentifier.

If neither claim is present, or the value is not a well-formed identifier, it throws MissingUserIdClaimException rather than returning a default, which reaches the client as 401. Use TryGetCurrentUserId where an anonymous caller is expected.

Usage

using System.Security.Claims;
using AlmightyShogun.AspNet.Auth;

Guid identifier = principal.GetCurrentUserId();

Returns

The caller's public identifier.

Type signature

public Guid GetCurrentUserId();
