Dotnet debugger needs fixing

The biggest bug in the world is not being able to use the real dotnet c# debugger, A) yes I have a hacked a work around B) third party thing like dotrush are not a answer C) we want the bug fixes so we can you use the MS debugging tools, my own hack to implement is a nightmare everytime you issue a new updater I lose 2 hours on getting the thing working right again inclusive of crusor crashing all the time, please implement a fix for debugging C# & F# with the official Microsoft debugging tools
