Malcolm, The article you referenced in the first post is probably the best thing out there. I haven't seen anything specific to .net on ts, so general .net stuff from Microsoft is probably as good as you can find also. In general, .net apps should require more memory on a TS, not less. This is especially true with the 1.0 and 1.1 frameworks, however Microsoft is improving the sharing in the new 2.0 framework. Initial look at using 2.0 indicates an improvement over the old, but the apps will (usually) reguire more memory than an equivalent "unmanaged" app. Garbage collection is also an issue (again improved in 2.0), as it is with java. One may still want to develop in .net, however, due to reduced development time and/or access to new functionality. Care should be taken in design to remember scalability. Well designed .net apps on a terminal server must consider offloading some functionality to other servers (after all, that is what all that flexibility is about) by implementing web services on other machines. tim _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of BRUTON, Malcolm, FM Sent: Wednesday, February 15, 2006 4:37 AM To: 'thin@xxxxxxxxxxxxx' Subject: SPAM-LOW: [THIN] .net on Terminal server (Citrix actually) Anyone got a good guide on .net applications on TS. Looking for mainly scalability stuff. I know the answer is to test and test again but looking for something that explains .net and how well it scales. Such as, my understanding is that with .net it will load a single DLL for all users if required rather than loading that DLL 30 times for instance.
