intercepting-commands

To intercept Visual Studio commands, use the VSIX Community Toolkit's VS.Commands.InterceptAsync to attach before or after handlers to known commands, or implement VSSDK's IOleCommandTarget via IVsRegisterPriorityCommandTarget for in-process interception.

Yes, you can cancel, replace, or augment default Visual Studio command behavior like Save or Build by intercepting the command to run custom logic instead of the default handler using VSSDK or VSIX Community Toolkit approaches.

No, the VisualStudio.Extensibility out-of-process model does not support command interception. For related scenarios in this model, consider using event-based approaches like IDocumentEventsListener instead of direct command interception.

The best way to run logic after a Visual Studio command executes is hooking into DTE CommandEvents.AfterExecute or using post-execution patterns with VSSDK, while the VSIX Community Toolkit supports after-interception directly via InterceptAsync.

To register a priority command target for in-process command interception in VSSDK, implement the IOleCommandTarget interface and register it using IVsRegisterPriorityCommandTarget within your extension package.
