In my Windows Forms project System namespace is overlaps with MyApp.System namespace.
I get CS0234 error: "The type or namespace name "Windows" does not exist in the namespace "MyApp.System" (are you missing an assembly reference?)" in "MyWindow.Designer.cs".
Yes, I know that I could change System.Windows to global::System.Windows and it will work for a while, but when my window UI is touched MyWindow.Designer.cs is regenerated and problem returns.
