We addressed these concerns in the support ticket you submitted, but I will still use the opportunity to summarize the information here for the community.
We have seen a similar issue in the Windows and VS clients of AppBuilder when saving a change in the project properties of a project will reset all plugins. We have already addressed the issue and a fix will be available with our upcoming 2.9 release due in April.
I am not sure if you have encountered the same issue and if you feel the case is different, it would greatly help us if you can share the exact steps that led to the reported behavior on your side.
As for the AppBuilder
updates - in Visual Studio
you can choose to ignore an update since this client can work, let's say, somewhat separately from the cloud services. At the same time, the Windows
and In-Browser AppBuilder
clients are closely coupled with the cloud services since they actually work on the cloud - the projects are stored and build on the cloud. This is the reason why these clients have to be updated along with any cloud service update. I would even recommend keeping the Visual Studio AppBuilder
extension updated to ensure it takes full advantage and works smoothly with the latest update of the Telerik Platform cloud services.
