In order to disable component designer in classes it is simple to add just [System.ComponentModel.DesignerCategory("")] attribute to it, however it does not work for any classes derived from this class in any generation. E.g:
[System.ComponentModel.DesignerCategory("")]
public class A:ServiceBase { } //Designer is disabled here
public class B:A {} //Designer is enabled here
[System.ComponentModel.DesignerCategory("")]
public class B:A {} //Designer is enabled here too
[System.ComponentModel.DesignerCategory("Code")]
public class B:A {} //Designer is enabled even here
This happens, of course, in any other generations and permutations. E.g.
//Whatever attribute here
public class C:B {} //Designer is enabled here
Does anybody ever tried to get rid of it? Why component model tries to add designer support even if it explicitely disabled in first generation?
Thank you
