[Go] Main method of WPF

The WPF program throws such an error:

Program ' SQLiteManager.exe ' does isn't contain a static ' Main ' method suitable for an entry point

The problem arises from the fact that I created a WPF application, I excluded the App.xaml file from the project, and then I included it, and this inadvertent operation created a problem, and I learned the WPF build action. When the build action is set to ApplicationDefinition, the WPF program generates the static ' Main ' method.

Like WinForm, WPF also needs a application to govern some global behavior and operations, and only one application instance exists in each Domain.

Application provides a number of useful properties and methods.
Current: Gets the default application instance in Domain.
MainWindow: Gets the main window instance.
Windows: Gets all instances of the Window that are instantiated.
Shutdownmode: Specifies the Application.shutdown mode, including the main form close, the last window closes, and the manual call to Shutdown ().
Properties: A thread-safe global dictionary that can be used to store a common information.
Shutdown: This method terminates application Process, which returns an exit code to the operating system.
