That's my understanding of it...
There will be certain deployment issues to be considered- for instance on a 64 bit machine, 32 bit software will be installed into a Program Files x86 folder, but other than that you shouldn't really have any problem. I often create (and run) bits and pieces on my home system (64 bit), compiled as 32 bit, and run them perfectly satisfactorily on work's 32 bit system without any issue... Martin.

The reason for this questions is because of our servers. Our Development, QA machine and User testing servers are all in 32 bit and only the production server is 64 bit. I didn't quite understand "By staying with 32bit you can deploy to both 32 and 64bit environments " .If I am not wrong ,can I use the dll's currently I am using 32 bit machine just like that in 64 bit machine ?. Carol , Thank you for the reply. I will check on that "AnyCPU" mode.

Try to compile you code with the "AnyCPU" mode. after that you must control each dll with ILSpy that any of you assembly are in "AnyCPU" mode. If all you assemblies are in AnyCPU mode, you can use it with x86 or x86_64 OS. If you can't compile in AnyCPU mode. My advice is to compile in "x86" mode in order to force x86 execution mode. My 2 cents Le 22/03/2012 17:11, Martin Milan a écrit : Vanitha, I am not part of the log4net team, and the following are my own view, and not necessarily those of my employer. Basically, all of the DLLs in your application must be of the same architecture - either all 32bit, or all 64 bit. You can't have so many in one and so many in the other. So long as you keep to that, you shouldn't have too much difficulty. The reason you can use the 32bit Dlls on your 64 bit machine comes down to something known as Windows on Windows - basically it emulates a 32bit environment for your app and on you go. You don't have to do anything - so long as all your dlls are 32 bit, it will just work. If you want to move to 64bit, you'll need to compile all of your Dlls - that's your app and anything it references (including log4net, excluding GAC) will need to be recompiled as 64 bit assemblies. I would question why you want to do this - by doing it you will prevent your application from being able to be deployed in 32 bit environments. By staying with 32bit you can deploy to both 32 and 64bit environments. By moving to 64 bit you will lose that, so I would want a reason to make that transition - and a better one than "it just sounds better..." Cheers, Martin.

The application uses a dll ,which has the log4net error logging code with below dll's referenced in there using log4net; using log4net.Config; and I am using EventLogAppender, RollingFileAppender and custom sendAlertAppender.MultiThresholdNotifyingAppender,sendAlertAppender . Please let me know ,whether it's going to be any issue .
