I provided a talk in Mountain View from the Southern Bay .Net consumer Group conference on August fifth. It was a broad talk about ClickOnce implementation and the ways to put it to use. Almost everyone into the area is a Windows kinds or WPF creator, which looks rarer and rarer today as anyone migrate to web software. There had been countless questions, and a lot of close conversation about points that people want changed in ClickOnce deployment.
The quintessential frequently wanted element because appointment as well as in the MSDN ClickOnce message board should put in a ClickOnce software regarding people instead a specific user.
This is challenging because data files is stored in the consumer’s visibility, where the consumer possess read/write benefits. One of many design purpose of ClickOnce will be offer a deployment method which enables customers to put in solutions without higher privileges. Installing a loan application for every consumers requires privileges.
Another layout purpose would be to protect the consumer maker from troubles as a result of program installments. Can you keep in mind a€?dll hella€?? It was the problem that taken place when another software arrived and changed a dll that you were dependent on, and triggered issues for the job, or vice versa.
In a ClickOnce deployment, you’re able to incorporate the majority of the dll’s in your area utilizing the http://datingmentor.org/pl/dabble-recenzja implementation, instead setting up all of them in the GAC or the microsoft windows system directory. (this might be leaving out, definitely, the .NET Framework alongside necessity programs such as for instance SQLServer Express.) You can even deploy the SQL Compact model dll’s or DirectX dll’s. This enables you to manage strict version controls on dll’s you include in your deployment. Microsoft would need to figure out an easy way to deal with this when the application happened to be deployed for all consumers; should they weren’t cautious, you could potentially effortlessly end up in dll hell once more.
Conversely, as long as they merely made a decision to place the documents according to the each Users visibility, yet again you have the permissions difficulties that Microsoft sought for to handle with ClickOnce implementation, considering that the user can’t write to the people records without increased privileges. Furthermore, If Microsoft kept the deployed data files when you look at the a€?All Usersa€? folder, they would need to determine what to-do if UserA was actually signed on utilizing the application, following UserB signed on and there had been an update readily available. Do you ever start UserA? Will you leave the modify because UserA is already operating the application form? What is UserA always departs his account logged on? How could you ever before perform an update?
This demand has become offered to Microsoft, but I haven’t heard of any intends to include a change for this in .NET 4.0, thus I wouldn’t count on any fast outcome. Doing an all-users apply is actually counter to the layout goals of ClickOnce deployment, and so I thought it will be something everyone has to live with, at the least for now. Making use of XCopy or a setup & implementation plan and going your own incremental revise methods is the path to take any time you definitely need an All Users construction.
