Blazor WASM应用中同时支持EntraID与自定义JWT双认证的实现问题咨询

我想在Blazor WASM应用里同时支持EntraID认证和自定义JWT认证，让用户自己选择登录方式，这可行吗？

当我已经把EntraID的认证方案跑通后，再添加一个自定义的AuthenticationStateProvider实现来存储用户登录状态时，应用就没法通过EntraID登录了，还会抛出以下异常：

System.InvalidCastException: Specified cast is not valid.

at Microsoft.Extensions.DependencyInjection.WebAssemblyAuthenticationServiceCollectionExtensions.<>c__11[[Microsoft.AspNetCore.Components.WebAssembly.Authentication.RemoteAuthenticationState, Microsoft.AspNetCore.Components.WebAssembly.Authentication...

我的自定义认证类代码如下：

public class ApiAuthStateProvider(AppStatus appStatus) : AuthenticationStateProvider
{
    private readonly AppStatus _appStatus = appStatus;

    public async override Task<AuthenticationState> GetAuthenticationStateAsync()
    {
        return await Task.FromResult(CreateState());
    }

    public void StateChanged()
    {
        var authState = Task.FromResult(CreateState());
        NotifyAuthenticationStateChanged(authState);
    }

    private AuthenticationState CreateState()
    {
        if (!_appStatus.UserLogged)
            return new AuthenticationState(new ClaimsPrincipal(new ClaimsIdentity()));
        else
        {
            var claims = new List<Claim> { new(ClaimTypes.Name, _appStatus.UserName ?? string.Empty) };
            claims.AddRange(_appStatus.UserRoles.Select(_ => new Claim(ClaimTypes.Role, _.ToString())));
            var anonymous = new ClaimsIdentity(claims, "Token");
            return new AuthenticationState(new ClaimsPrincipal(anonymous));
        }
    }
}

有没有办法让这两种认证方式同时正常工作呢？
