Microsoft addresses Visual Studio extension woes
Microsoft is working on a new extensibility model for its signature Visual Studio IDE, with the goals of improving the reliability of extensions and making them easier to write. Extensions are to be supported locally and in the cloud as part of the plan.
Elaborating on the effort October 28, Microsoft cited an issue in which Visual Studio would crash because of an extension. Current in-proc extensions are subject to few restrictions over how they can influence the IDE and other extensions, allowing them to corrupt the IDE if an extension crashes or experiences an error.
