I assume C# is not really supported language? Just trying to understand how to use outputs from stack A to stack B.

Currently, all types exported from stacks must be serializable using Pulumi's Output serialization.

Object

is not serializable in general as the error notes. What are the actual types of the data pulled in from the other stack? If you can express that real type here (in terms of the real serializable data structures), I believe it should work. https://github.com/pulumi/pulumi/issues/3690 is related to this. cc also @tall-librarian-49374 who may have further thoughts.

Do we have good legitimate examples? I reference my issue above. If i can find a good pattern, like that of python I can move forward using c# with pulumi
