             Summary: The public API should be declared virtual
                 Key: CMIS-936
                 URL: https://issues.apache.org/jira/browse/CMIS-936
             Project: Chemistry
          Issue Type: Improvement
          Components: dotcmis
    Affects Versions: DotCMIS 0.6, DotCMIS 0.7
         Environment: Windows 7, DotNet 3.5
            Reporter: Patrice Collardez


The public API of DotCMIS is not completely declared virtual, and it prevents the polymorphism
to work as expected, especially when creating a new ObjectFactory and specialized objects.

Long explanation:
With Java, every method is implicitly declared virtual, therefore overriding a method in a
subclass is as simple as a redeclaration and the polymorphism works as intended whatever the
cast of the subclass to any of its parent class or interface.
With C#, every method is not declared virtual, therefore redeclaring a method in a subclass
does not make the polymorphism works: the first declaration of the method is used considering
the cast level in the inheritance graph.
In order to have the same behavior with C# as the one we have with Java, every method should
be declared "virtual" and every redeclaration should be declared "override".
