I offered a chat in Mountain see in the southern area Bay .Net consumer class meeting on August fifth. This is a broad mention ClickOnce Deployment and the ways to put it to use. Almost everyone during the area ended up being a Windows paperwork or WPF developer, which sounds rarer and rarer nowadays as folk migrate to online programs. There have been countless issues, and many great debate about points that individuals need altered in ClickOnce deployment.
One particular often required feature for the reason that conference along with the MSDN ClickOnce message board will be download a ClickOnce application for several customers instead a specific consumer.
It is difficult considering that the data become stored in an individual’s profile, where in fact the individual features read/write privileges. One of the concept aim of ClickOnce is to provide a deployment techniques which enables customers to set up solutions without escort service Beaumont TX higher benefits. Installing an application for all people needs privileges.
Another layout goal were to protect the customer machine from issues due to program installations. Do you ever bear in mind a€?dll hella€?? This was the situation that happened when another program arrived and changed a dll that you were influenced by, and caused issues for your application, or the other way around.
In a ClickOnce implementation, you can incorporate most of the dll’s in your area because of the deployment, in the place of setting up them within the GAC or perhaps the windowpanes program directory site. (this is exactly leaving out, needless to say, the .NET structure and various other prerequisite solutions like SQLServer present.) You can deploy the SQL Compact release dll’s or DirectX dll’s. This permits you to definitely keep rigorous variation regulation from the dll’s which you use in their deployment. Microsoft will have to ascertain an effective way to manage this in the event the software happened to be implemented for several customers; as long as they weren’t mindful, you could potentially conveniently end in dll hell once more.
Having said that, should they simply chose to place the data files underneath the completely consumers visibility, once more there is the permissions challenge that Microsoft sought to look at with ClickOnce implementation, considering that the consumer can not compose to people documents without elevated benefits. Additionally, If Microsoft kept the deployed records when you look at the a€?All Usersa€? folder, they will need to determine what accomplish if UserA had been signed on utilising the application, then UserB logged on and there ended up being an update offered. Do you kick-off UserA? Do you ever forego the modify because UserA is already working the program? What’s UserA usually leaves their account logged on? How will you actually carry out an update?
This consult has become offered to Microsoft, but i’ven’t been aware of any plans to put an alteration to the in .NET 4.0, so I wouldn’t count on any rapid success. Carrying out an all-users apply is actually counter into the layout plans of ClickOnce implementation, so I thought it’s going to be something everyone has to call home with, about for the present time. Making use of XCopy or a setup & deployment package and going a incremental revise methods is the way to go should you completely must have an All Users set up.
