If you’ve ever had this error pop up when deleting a managed solution on your CRM 2015 box:
The Main() component cannot be deleted because it is referenced by 1 other components. For a list of referenced components, use the RetrieveDependenciesForDeleteRequest.
You should use this to quickly get the dependency information:
First, go to the solution’s URL (will be like https://CONTOSO.CO/COCO/tools/solution/edit.aspx?id=%7b2BE0D3AD-DF66-4747-8AA0-A5BA16B146D3%7d
Then run this bookmarklet, which I call GetSolutionDependencies:
It will extract the id for that solution, then go to a page in your CRM org to show more details. Only tested in IE11 so the context may differ of course.
