adding c4codataapi edmx generating csn, the framework reports issues on duplicate properties.
There are two properties localLang and LocalLang, but with different case. I think this is valid from edmx perspective, but not handled by cds in general.
The cap service will crash on start with this duplicate props error. Workaround is to delete one prop from csn.
Also trying to call ServiceRequestCollection leads to serialisation issues. What i figured out, is that the returned DateTimes could not be handled correctly.
it would be great, if this could be fixed to be able to use cap for C4C/SalesCloud/ServiceCloud out-of-the-box.
