In VB the feature requested here was called Edit and Continue. VB users loved it. The original release of VB.net did not have it, and was the highest priority feature to add back. When we added it back into Visual Studio, C# got it as well because it’s users demanded it. Anders was trying to ensure genetics made it into .net 2.0 and did not want the feature. I know he wrote some critiques that it encourages producing bad code. I added it in the debugger, while each language team had work, and there was a massive work for the CLR. Changing the current function is actually pretty easy .. it’s when you need to remap the instruction pointer in functions that have been edited multiple times and have frames trapped on a callstack across multiple threads.

Edit and Continue also works in VS C++ and has been a godsend for me when tweaking DSP code. This particular feature has remained unmatched by other IDEs/toolchains for what, 15 years? That's pretty impressive stuff you've worked on. It's certainly not adapted to all domains, but in DSP applications where you're looking at immediate audio/video feedback (in my case, audio synths and effects) it makes a lot of sense to regularly switch into "tweaking mode" - not only in order to refine the code, but also to get a better understanding of how small variations in each part of the code can affect the live output, which can be a large portion of the work you'll do in DSP applications. It's just awesome, you're working on a full-fledged application and you can turn it into a live editor at any moment.

  "Edit and Continue also works in VS C++ and has been a godsend for me when tweaking DSP code. This particular feature has remained unmatched by other IDEs/toolchains for what, 15 years?" Edit and continue has worked in C++ toolchains and editors before VS, and continues to work now :) Fix and continue support, for example, existed in GDB way back in 2003 (see, e.g., http://www.sourceware.org/ml/gdb/2003-06/msg00500.html http://www.sourceware.org/ml/gdb/2003-06/msg00500.html) and in forks of gdb well before, which others used for C++ (hence the "implemented again" headline). The message covers some of the other places this was implemented. IIRC (it's been a while), HP WDB support for this goes back to the very late 90's. Now, i'm certainly not going to claim these IDE's were as good as VS, but they definitely had edit and continue for C++. It's definitely a technical accomplishment, but it's not unique.
