Hi @lindexi - thank you for fixing this. There is a build error, could you please also add a new .csproj for this?

😵 Project missing. A project (and optionally a solution file) must be in this directory or one of the parent directories to validate and build this code

@IEvangelist Sorry, I can not compile the project after I added the csproj file. Because we define the same MainWindow class in example.cs and example3.cs and example4.cs

Should I rename the MainWindow to MainWindow3 or MainWindow4 in example3.cs and example4.cs ?

Why is this needed?

@Youssef1313 Because we define the same MainWindow class in example.cs and example3.cs and example4.cs

The problem with EnableDefaultCompileItems being false is that it beats the purpose of the csproj, which is to make sure the code compiles properly. If the examples are completely independent, I'd make a folder for each of them, each with its own csproj. @IEvangelist Do you agree?

[Youssef1313]

Actually example3 and example4 doesn't seem to be referenced. So they can just be deleted?

[lindexi]

@IEvangelist Can I delete the example3.cs and example4.cs file and create the MainWindow2.xaml file?

[IEvangelist]

You'd have to verify that those two files are in fact not being referenced, if you can prove that then yes.
