Browse and select a .Net type - documents


I am new to using UI Path.
Can anyone help me with the documentation for the list of functions under the Referenced assemblies.
I would like to have the list with the data type and its purpose / the usage.

Thanks in advance,

+1 . is there any .NET style documentation for the .NET objects we can access in UiPath Studio (e.g. QueueItems, Transaction Item, etc) ?
