Using Multi Factor authentication with Xrm.Tooling.CrmConnectControl

Question

I have tried logging in to an Multi Factor Authentification (MFA) enabled 365 Online environment using both the Xrm.Tooling.CrmConnectControl from the CRM SDK Template (added to existing project) downloadable at https://marketplace.visualstudio.com/items?itemName=DynamicsCRMPG.MicrosoftDynamicsCRMSDKTemplates and the one provided in the lastest SDK SampleCode called QuickStartXRMToolingWPFClient. I have not successfully logged into the MFA environment in either case. Ofcourse all the non-MFA environments I have tried to log into works as intended using both the described solutions.

In Plugin Registration Tool v.8.2.0.8411 it is possible to log into an MFA-enabled environment by leaving both User Name and Password blank when targeting Deployment Type Office 365. However when using the CrmConnectControl from the Template/SDK leaving User Name and Password blank results in the error message "A user name is required." alternatively "A password is required.".

Does anyone know if there is a way to use the Xrm.Tooling.CrmConnectControl to authenticate to a MFA environment in the same way as it is done in the Plugin Registration Tool?

Thank you for including this, it just solved my issue "In Plugin Registration Tool v.8.2.0.8411 it is possible to log into an MFA-enabled environment by leaving both User Name and Password blank when targeting Deployment Type Office 365" — Chris Snyder

The solution is for the SampleCode from the latest SDK for Dynamics 365.

First of all I see that this QuickStartXRMToolingWPFClient source code uses outdated SDK - go to nuget package manager and update all Microsoft.CrmSdk packages to the latest versions (don't update Microsoft.IdentityModel by yourself - it will be updated to the proper version as a dependency for the SDK assemblies).

Now, inside CrmLogin.xaml.cs you have a function Window_Loaded and CrmConnectionManager initialized like so:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    //some code
    mgr = new CrmConnectionManager();
    mgr.ParentControl = CrmLoginCtrl;
    mgr.UseUserLocalDirectoryForConfigStore = true;
    //some code
}

you must add the following lines:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    //some code
    mgr = new CrmConnectionManager();
    mgr.ParentControl = CrmLoginCtrl;
    mgr.UseUserLocalDirectoryForConfigStore = true;
    mgr.ClientId = "2ad88395-b77d-4561-9441-d0e40824f9bc";
    mgr.RedirectUri = new Uri("app://5d3e90d6-aa8e-48a8-8f2c-58b45cc67315");
    //some code
}

Rebuilt and it will work exactly as PluginRegistrationTool

What are the Guids in ClientId and RedirectUri? Why do not we specify them in Plugin Registration Tool configuration?
