title: Show own app in list for default browser (C#) Windows10
body: <p>I want my application to be displayed under the default browser. I found many many articles for that in the last 3 days. No solutions seems to be right.
  Here it should appear:
  <a href="https://i.stack.imgur.com/LeqVc.png" rel="nofollow noreferrer">enter image description here</a></p>
  <p>It should work for Windows 10. In the article ( <a href="https://docs.microsoft.com/en-us/windows/win32/shell/default-programs?redirectedfrom=MSDN" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/windows/win32/shell/default-programs?redirectedfrom=MSDN</a> ) is shown which registry entrys should handle this. but it doesn't work. Yes I've read the alert about the way changed how the standard app in win 10 is set but i don't want to set it programmatically, I want my app to be displayed there.
  Does anyone have more specific informations for me?</p>
  <p>My Code set the registry entries from the article and in the registry, I can see them after using my app. So I won't show my code for adding a registry key here but of course, is there a solution, i will add the code...</p>
  <p>Thank you!</p>
