Extend TypeScript Definitions

Hi,

i have a custom (generic) activity - where the user can select an object type - and based on this we create a new business object.

It is simple like this:

[ActivityInput(Hint = "Objekttyp", OptionsProvider = typeof(ObjectTypeProvider), UIHint = ActivityInputUIHints.Dropdown)]
public string ObjectType { get; set; }

[ActivityOutput(DefaultWorkflowStorageProvider = TransientWorkflowStorageProvider.ProviderName)]
public object Result { get; set; }

Now i want to provide Intellisense for the Result property. Currently it renders as object type "any" - since it is an object.

Would it be possible to extend the RenderJavaScriptTypeDefinitions class with some event or something like this - i think the main part will be the RenderActivityProperty - when i have a reference here to the activity instance - i could change the output for the Result property from Result(): any; to Result(): MyCustomType; ?

Start with RenderJavaScriptTypeDefinitions and its RenderActivityProperty method, which the issue identifies as the likely extension point. Determine how the activity instance could provide a custom type for the Result property, replacing the generated any type with MyCustomType. Done means the generated definition supports this customization for the described activity.
