I gave a chat in hill View in the southern area Bay .Net individual people appointment on August fifth. It was an over-all talk about ClickOnce implementation and the ways to use it. Almost everyone inside space was a Windows kinds or WPF developer, which seems rarer and rarer these days as people migrate to internet applications. There had been countless questions, and many great conversation about things that men wants changed in ClickOnce deployment.

By far the most regularly asked for function in that conference plus the MSDN ClickOnce Forum would be to download a ClickOnce program for every users without a certain consumer.

This is harder because data files were kept in an individual’s profile, where in actuality the consumer have read/write benefits. One of the concept needs of ClickOnce is always to provide a deployment techniques which enables customers to put in solutions without elevated rights. Setting up a loan application for many consumers need rights.

Another concept aim were to secure the client equipment from trouble due to software installments. Do you remember a€?dll hella€?? This is the challenge that happened when another application came along and replaced a dll that you were determined by, and caused issues for the job, or the other way around.

In a ClickOnce deployment, you can easily include a lot of the dll’s in your area using deployment, rather than installing all of them when you look at the GAC or even the windows program directory site. (this is exactly leaving out, without a doubt, the .NET platform also necessity applications such as for example SQLServer present.) You can even deploy the SQL lightweight model dll’s or DirectX dll’s. This enables one manage tight variation controls from the dll’s which you include in the deployment. Microsoft would need to determine a way to handle this in the event the program were deployed for all people; when they just weren’t mindful, you can effortlessly end in dll hell again.

Conversely, as long as they simply chose to place the data files in every consumers visibility, again you’ve got the permissions complications that Microsoft found to deal with with ClickOnce deployment, considering that the consumer can’t create to people records without elevated rights. Also, If Microsoft saved the deployed data in the a€?All Usersa€? folder, they will have to determine what to do if UserA is logged on using the software, and then UserB logged on there had been an update available. Do you ever kick-off UserA? Do you actually leave the upgrade because UserA is already working the program? Understanding UserA always simply leaves his levels signed on? How could you actually ever do an update?

This request has become handed down to Microsoft, but We haven’t been aware of any plans to consist of a change to the in .NET 4.0, and so I won’t expect any rapid outcome. Starting an all-users apply are counter with the concept goals of ClickOnce implementation, and so I imagine it will likely be something everybody has to reside with, about for the time being. Making use of XCopy or a setup & deployment bundle and rolling your own personal incremental update methodology would be the path to take if you definitely must have an All Users set up.
