Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

In the documentation of the caching mechanism, there is GetSession which isn't implemented in the V12.13.2. There is only a watch function implemented in the interface. But it isn't clear if we still have to have a reference to the session Disposable

Here is the link to the file:

Steps to reproduce

1. Go to Documentation
2. if you try to implement the piece of code will not work due to the fact that GetSession isn't implemented anymore
