❔ How to make a method returning type T but only taking subclasses of a certain class ?

I'd like to make a function that takes the type T as an "argument" (T MyMethod<T>()), but the type T must be equal to Type Z or subclass of Type Z, how do I do that ? I'd like it search through defined dictionaries that are all typed as subclasses of Type Z.

❔ Associate an application with an extension name (e.g., .asset, .ext, .lol, etc...)

Hello, I would like to know how I can link my app with a custom extension name, in my case it's .rift but it can be any extension name for other apps so I will try to ask as much as possible in a general way. I have read the documentations there: https://learn.microsoft.com/en-us/visualstudio/extensibility/registering-verbs-for-file-name-extensions And here: https://learn.microsoft.com/en-us/windows/win32/shell/how-to-register-a-file-type-for-a-new-application I would like if, first, my code is valid (i'd like to not break my registry before trying) And if not, how can I do that ?

    public static void AssociateExtension(string Extension, string Description, string KeyName, string ExecutableName)
    {
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension,
            "", KeyName);
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension + @"\OpenWithList\" + ExectuableName,
            "", "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension + @"\OpenWithProgids",
            KeyName, "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\Applications\" + ExecutableName + @"\Shell\Open\Command",
            "", $"\"{Application.ExecutablePath}\" Project=\"%1\"");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName,
            "", Description);
        //Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName + @"\DefaultIcon", "", "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName + @"\shell\Open\Command",
            "", $"\"{Application.ExecutablePath}\" Project=\"%1\"");
    }

    public static void AssociateExtension(string Extension, string Description, string KeyName, string ExecutableName)
    {
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension,
            "", KeyName);
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension + @"\OpenWithList\" + ExectuableName,
            "", "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + Extension + @"\OpenWithProgids",
            KeyName, "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\Applications\" + ExecutableName + @"\Shell\Open\Command",
            "", $"\"{Application.ExecutablePath}\" Project=\"%1\"");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName,
            "", Description);
        //Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName + @"\DefaultIcon", "", "");
        Registry.SetValue(@"HKEY_CLASSES_ROOT\" + KeyName + @"\shell\Open\Command",
            "", $"\"{Application.ExecutablePath}\" Project=\"%1\"");
    }

Will the output be ?:
