Visual Studio Edit and Continue not working anymore

Anonymous — Tue, 25 Jun 2013 04:50:10 GMT

I'm new, hoping you can help. I develop AutoCAD using .NET, I use the Edit and Continue feature in Visual Studio 2008 while debugging and testing what I wrote. I recently got a new machine and now my Edit and Continue doesn't seem to work anymore. Any ideas why not?

Hi,

Bad news: There is no Edit & Continue in VS on 64 bit period, see this Edit+Continue

I had this problem for months and months on my 64 bt machines. A lot of people say you can use edit and continue on 64 bit but I'm not convinced. Switch back to 32 bit and problem solved.

Thanks for the help. It definitely doesn't work, I've been trying for days. I can't go back to 32bit, the money I paid for my new computer would be a total waste!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Any other people had this problem and have it solved?

I feel your pain. When I upgraded our office equipment we got 64 bit everything. i spent weeks installing Win 7; 64 but. + All related software, then BANG. No edit and continue. It destroyed our workflow in the office. We tried every single option from every blog known to man for a full week. Then we tried to accept the fact that it was gone. In the end I had to spend another 2 weeks re-installing 32 bit and all software's.

What do you actually lose going back to 32 bit: Your ram if it's above 4gb is null. But you gain Edit & continue and the ability to step through code and hit break points. I don't know about anybody else but I couldn't do my job without this feature.

Sorry to be the bringer of bad news but I bet you end up switching back.

Good luck :D.

Hi,

>> but I bet you end up switching back

Or use VmWare or any other type of virtual pc with a 32bit Windows. So you can develop in that mode (having then edit&continue enabled) and you can test (and work) in 64bit mode on your master Windows. 😉

That''s a good idea. Is there any speed loss?

Hi,

I would not work on AutoCAD (using 3D or big drawings) as the display is not that fast within the VmWare emulation.

But for developement ... I guess you won't fill the keyboard-buffer more fast than VmWare can catch it 😉

Sometimes, if you do some optimization you can work within a virtual pc faster than on your host system, because you only install what you need for development, so no apps, no office, no antivirus-software, no firewall (depending on allowing the VmWare to connect to internet or not) and so on.

E.g. my Win7x64 on the host-system (including database server) needs about 2GB to have the os loaded. My VmWare os needs just 300MB 😉

Thanks for the information.

Very much appreciated.

Hi,

An expensive alternative is to work in a 32 bit Windows Server OS (I'm stuck in 2008 Server R1), but it's not supported, and 2014 refused to install in it, but 2008 Server has no 4GB memory limitation so it's a better platform for up to AutoCAD 2013.

Sorry - Edit and Continue definitely does not work debugging 64bit applications on 64bit Windows. This is a general issue with Visual studio, that is not related to AutoCAD itself.

Thanks.

What about running 32bit AutoCAD on 64bit Windows, is it possible? Has anyone tried?

Re: Visual Studio Edit and Continue not working anymore

fenton_webb — Wed, 26 Jun 2013 14:30:28 GMT

It's totally possible to make AutoCAD 32bit run in Windows 64bit, but we don't support it. Technically speaking I don't see any reason why it wouldn't work as normal - yes, it would certainly solve your edit and continue issue in the debugger. As I have said before, if it solves an issue for you, then go for it.

FYI - We don't support 32bit AutoCAD on 64bit Windows because their is a huge effort testing each platform configuration. Because we already have a 64bit version of AutoCAD that runs on 64bit Windows it doesn't make business sense for us to test and QA a scenario that is most likely < 0.01% of our business.

I'm glad that's been said out-loud as there were a few missleading posts that implied that is was possible.

Which posts?

I don't know if i got the wrong end of the stick when reading them but it implied I thought that hitting breakpoints on a 64 bit machine was possible. It was over a year ago. I can't find them right now but can have a search later if needs be?

Re: Visual Studio Edit and Continue not working anymore

fenton_webb — Wed, 26 Jun 2013 16:01:30 GMT

Actually, not hitting break points is different topic to this one, but i will say that it's similar in a way because it also occurs while debugging AutoCAD 64bit. The problem is that AutoCAD uses a stack swapping technology called 'Fibers' (Fibers are a deprecated technology from Microsoft which we are working on removing) and fibers do not work well with .NET, and in turn mess up Visual Studio break points on 64bit.

The quickest solution is to set NEXTFIBERWORLD=1, however, the downside with that setting is that multiple document commands will stop working, as will posting commands from the Ribbon.

Is someone from Microsoft watching? I got this e-mail litteraly 5 mins ago:

Edit and continue now available for 64 bit. :d.

Many tx for all the information.

Sorry but I didn't read anything that I wanted to run with, however, further investigation using some of the keywords on this thread unearthed a 'longbow' solution which has now solved my problem. I am now running 32bit 2010, 2013 and 2014 on my 64bit machine (no 64bit versions of AutoCAD at all), with Edit and Continue working fine, and I'm back up and working as before.
