Adding 'Context=Edit' to enable full data retrieval

[OWAA-Rick]

I have cloned the app, added ability to have "Context=View|Embed|Edit" appended to GET requests. This requires an addtl argument on all methods that result in GET.

Question is how would you prefer to implement?

1. Extending all method signatures with optional Context enum (which already exists); however this places it after CancellationToken parameter which traditionally is last parm in a method signature.
2. Overloading all signatures with a required first parameter of Context; this would become the code-bearing method and originals would simply invoke, passing a default Context; however the general coding philosophy seems to be to have defaulted optional parameters wherever possible.

I favour 2 - anyone have thoughts or care to vote?
