Windows Forms (WinForms) is a graphical (GUI) class library included as a part of Microsoft .NET Framework. Providing a platform to write rich client applications for desktop, laptop, and tablet PCs. So let get started with a demo application.

To create a window form application open visual studio 2015 (If not available then download from Microsoft website). Click on File in menu and create a new project.

Choose the “Window form application” from the list under Templates -> Visual C#->windows and name your project.

Now we have our window form application.
Now rename the form1 to your required name. This name is going to be used when required.

To rename go to the solution explorer select the form1.cs and rename it.

But still the title is unchanged as form1, so select the form go to property and change Form1 to your desired name under Text.

Now our window form is ready on which we can build our application.
