what happen to break-modifycode-continue

VB6 had the ability to pause your execution while debugging, messing with
the code, and continue executing right from where you left off. Is DotNet
ever going to have this capability? I really miss it.

Hi William,

No you do not miss something, break, edit (not for everything) and continue
will again be in the next version. However as soon as you are used to it you
will see that it is not such a big issue.

However just my thought the last part.

Currently, that's not possible. By default, it's not event possible to
edit code in the text editor if the project is in run mode. You can
change that in the IDE's settings, there is an option that will allow
you to edit code when debugging. Notice that this will not be the same
as edit & continue as it doesn't apply the changes when continuing the
execution.

Real edit & continue as known from VB6 will be back in VB 2005 (Whidbey)
which will be made available next year. This is a VB-only feature that
is not available in C#. The feature is currently already available in
the beta versions of VB 2005.

You have obviously never used this feature when debugging. When running a
long program that is crashing near the end of the program, being able to
edit and continue is a major productivity enhancer.

You do mean that all people (not only me) who already are using VB2002 and
VB2003 for a long time now are improductive developper?

No, I mean that edit and continue will increase your productivity even more.
I didn't say VS 2002 and 2003 developers weren't productive, just that edit
and continue is a productivity enhancer.

Not necessarily, but with edit & continue debugging experience is much
better and faster debugging/development is possible.

For those of you who aren't aware of this, MS-Visual C++ 6.0 and the earlier
MS Macro Assemblers also had primitive edit and continue. You could edit
code lines and change the value of scaler variables (stack and register
based). I would think that in a "managed" environment such as .NET, Edit
and Continue would be the de-facto debugging standard. .NET's managed
memory and CRL intermediate code make this an ideal environment for Edit and
Continue. The basic implementation would be to mark "source code
statements" in the CRL and replace them as blocks when the source is
changed. You can dump references to objects when the object value is
changed. In either case, you're simply orphaning data in the debugger and
the garbage collector will clean up after you. Obviously, there will be
instances where edit and continue features simply cannot work - warn the
user and let them make the choice to keep the edits or continue with the old
code.

This is a huge oversight by MS to not realize that this is a programmer
productivity enhancer and include this as a fundamental feature of the IDE.

Is this feature hard to implement - yes. But having worked both with and
without edit and continue debuggers, it's worth its weight in gold when
debugging long tasks. For short programs, it doesn't make that much
difference because the restart time isn't too bad.

Tha lack of E&C is one of the reasons why I don't like C# and I have
still problems writing VB.NET code. Something is missing. I have
developed a fairly large class library in VB 2005 preview versions with
E&C and I was happy to be more productive. Much more productive.

What is there an Extra line-break after web/user controls???
