I achieved this in Visual Studio 22 by using regex find and pressing hotkeys repeatedly to speed up the process. It is not fully automated but it is the best I can find without installing anything.

• Open Quick Find (ctrl+f)

• enable Use Regular Expressions

• Put the following expression in the text box \)\r?\n {8}\{

  • This will find any method where the line ends with ), and there are 8 spaces before {, which typically finds methods. This can be tweaked for tabs, different amounts of spacing ect., but does not account for comments

• In the dropdown of the arrow, select Find All

• In the Find window, double click the first line / method.

• Press F9 to add a breakpoint, Press F8 to skip to the next found result.

• Alternate between F9 and F8 as fast as possible (or create an autohotkey to do it multiple times)
