Environment

Release : 8.6
Component : CA Gen Generator, Proxy.

Resolution

The fundamental problem here is that the Gen Server Manager that the proxy is being generated for is not allowed to have nested repeating group views.
Support created a simple server PStep with nested repeating group views and the generation of its Server Manager with Consistency Check (CC) enabled at generation time failed with this ERROR message:
ERROR : ICCBR13E A Procedure Step with either window or cooperative packaging must not contain nested repeating group views in its import or export view set.

The .NET proxy generation/build then failed with the same messages as reported i.e. CS0029, CS0022 etc
Granted that perhaps it would be expected for a similar CC ERROR message to be shown for the Proxy Generation, and that is maybe something Engineering can address in the future.

So the solution to this problem is to remove the nested repeating group views in the server PStep and then regenerate the .NET proxy.
