Hi,

WinRT, Code First, DevForce 2012 7.2.

Following the documentation, I am testing Remote Server Method Calls (RSMC) and this functionality does not work properly.

During executing:
" ... InvokeServerMethodAsync(...);"

the error message appears:
"Constructor on type 'AppTest.AppTestEntityManager' not found."

Please find attached a very simple solution which exemplifies the problem (libraries removed).

Thansk in advance for any help.

For somewhat obscure and not well-documented reasons, the EntityServer will try to construct your sub-typed EntityManager for the RSMC call.  It will only look for a constructor with a signature accepting EM and EntityManagerContext arguments, so you can add a constructor like the following to work around the problem:
 
public AppTestEntityManager(EntityManager entityManager, EntityManagerContext entityManagerContext = null) : base(entityManager, entityManagerContext) { }
