Red, Green and Refactor is the three phase of Test Driven Development and this the sequence that get followed while writing code. When followed, this order of steps helps ensure that you have tests for the code you are writing and you are writing only the code that you have to test for.
Test-Driven Development starts with designing and developing tests for every small functionality of an application. TDD framework instructs developers to write new code only if an automated test has failed. This avoids duplication of code. The TDD full form is Test-driven development.
To create an MFC forms or dialog-based application. From the main menu, choose File > New > Project. Under the Installed templates, choose Visual C++ > MFC. Choose MFC Application from the center pane. Click Next to start the MFC Application Wizard. For more information, see Creating a Forms-Based MFC Application.
Test-driven development is a process of modifying the code in order to pass a test designed previously. In Software Engineering, It is sometimes known as "Test First Development." TDD testing includes refactoring a code i.e. changing/adding some amount of code to the existing code without affecting the behavior of the code.
To create an MFC forms or dialog-based application 1 From the main menu, choose File > New > Project. 2 Under the Installed templates, choose Visual C++ > MFC/ATL. If you don't see these, use the Visual Studio Installer to add them. 3 Choose MFC Application from the center pane. 4 Modify the configuration values as needed, then press Finish.
The MFC Application Wizard generates the appropriate classes and files for any of these types of applications, depending on the options you select in the wizard. The easiest way to create an MFC application is to use the MFC Application Wizard ( MFC App project in Visual Studio 2019).
The answer which has evolved over the last few years is, you don't apply TDD to the GUI, you design the GUI in such as way that there's a layer just underneath you can develop with TDD. The Gui is reduced to a trivial mapping of controls to the ViewModel, often with framework bindings, and so is ignored for TDD.
This is known variously as the Presentation Model (Fowler) the Model-View-ViewModel and DataModel-View-ViewModel architecture.
This approach removes the GUI layer from TDD and unit testing. It does not mean the GUI is never tested but just acknowledges that it is not cost effective to pursue automated GUI testing, particularly as part of TDD. Integration and user testing should cover the GUI.
Josh Smith's 2009 WPF article is a detailed explanation of MVVM with some testing.
More recently, Houssem Dellai's 2016 video Creating Unit Tests for Xamarin Forms Apps shows a XAML UI with bound ViewModel and walks through creating a unit test project

Why not. Here is a good article, from object mentor.
Found another blog post, TDD - Introduction to Moq. Its related to C# and VB.NET.
Checking out Myth and Misconception regarding TDD is a must.
Here is a book related to .NET, TDD in Microsoft .NET.
