Troubleshooting WPF Error: "Program does not contain a static 'Main' method suitable for an entry point"
If you're working with WPF (Windows Presentation Foundation) in C, you might encounter an error message stating, "Program does not contain a static 'Main' method suitable for an entry point." This error typically occurs when the application is unable to find the appropriate entry point to start the execution. Fortunately, resolving this issue is relatively straightforward. In this guide, we'll explore the possible causes of this error and provide step-by-step solutions.
Understanding the Error
The error message indicates that the WPF application is missing a static 'Main' method, which serves as the entry point for the program. The 'Main' method is essential as it is the starting point of execution for any C application. In the context of a WPF application, this method is typically found in the App.xaml.cs file.
Step-by-Step Solution
Follow these steps to fix the "Program does not contain a static 'Main' method suitable for an entry point" error:
Check 'App.xaml.cs'

Set Startup Object
Make sure that the correct startup object is set in your project settings. Right-click on your project in the Solution Explorer, navigate to 'Properties,' and under the 'Application' tab, set the 'Startup object' to the appropriate class containing the 'Main' method.
Ensure Correct Namespace
Ensure that the namespace in the 'App.xaml.cs' file matches the namespace of your project. Mismatched namespaces can lead to the application not recognizing the 'Main' method.
Check for Typos
Inspect your code for any typos or syntax errors that might prevent the 'Main' method from being recognized. Pay close attention to method signatures and braces.
Rebuild the Solution
After making the necessary changes, rebuild your solution to ensure that the changes are applied. This can be done by right-clicking on your project in the Solution Explorer and selecting 'Rebuild.'
Conclusion
By following these steps, you should be able to resolve the "Program does not contain a static 'Main' method suitable for an entry point" error in your WPF application. Remember to carefully inspect your code, check for the presence of the 'Main' method, and ensure that the project settings are configured correctly.
