I have used the Visual Studio 2008 SP1 debugger with F# and have not experienced this problem. What version are you using?
OK, I remember where I saw this. From the release notes of 1.9.6.2:
<quote> <i>Debugging and stepping in Visual Studio and other .NET debuggers has been improved. However, reliable stepping is only available if tailcalls are explicitly disabled through an appropriate command line compiler flag (e.g. <c><b>--optimize- notailcalls</b></c>).<i></quote>
I have used the Visual Studio 2008 SP1 debugger with F# and have not experienced this problem. What version are you using?
Yes, I'm using that same version (9.0.30729.1 SP. When I hit a tail recursive call I end up stepping through MASM code rather than F# source code. That's not particularly useful for me.
Does it step through the source code for you?
Regards,
Bill

I'm curious why the debugger gets confused when you single step into a tail recursive call. It complains that there is no source available and you end up stepping through IL code. I found a mention (somewhere?) recently about disabling tail recursion in order to allow debugging in these cases, but am curios what the problem is. Why can't the debugger handle a tail recursive call?
