Hi,
 
I've heard that there is a SysExtension framework that can be used instead of using switch cases to initiatlise sub classes.
 
Can someone write an example of how the class was with switch cases and how it became better with SysExtension framework -- please don't post urls fir your clarification 
I have the same question (0)

    SysExtension framework is one of two available frameworks for this purpose (the other is SysPlugin). The documentation (https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/register-subclass-factory-methods) explains differences between them.
     
    With these frameworks, the code creating instances don't need hard-coded names of classes. It lets a framework to find the right subclass based on some parameters.
     
    Here you can find more information about SysExtension framework, including an example: https://community.dynamics.com/blogs/post/?postid=31bbc085-ba95-4f75-a82a-de52a867005a.

    There you'll use your attribute, with a parameter or parameters as per your needs. In this example, you say that this class should be instantiated if the factory is called with "A" value.
