Remarks

When you need to break compatibility, the project system should first call AskForUserConsentToBreakAssetCompat before calling BreakAssetCompatibility.

The following call sequence is typical:

  1. Call the AskForUserConsentToBreakAssetCompat method to show a dialog box that asks for user consent. If the user does not agree to continue, this method throws a COMException with an ErrorCode of OLE_E_PROMPTSAVECANCELLED.

  2. If a COMException is not thrown, make the changes that break the compatibility.

  3. To finalize the compatibility break, call the BreakAssetCompatibility method.

  4. The BreakAssetCompatibility method calls the GetCurrentDesignTimeCompatVersion method to obtain a string that represents the current version of Visual Studio.

  5. The BreakAssetCompatibility method then calls the SetProperty method to set the project VSHPROPID_MinimumDesignTimeCompatVersion property to the value of the version string that was obtained in the previous step.
