Add support for multi select option set on the proxy classes
Starting from Dynamics 365 V9, Dynamics 365 has the new multi select option set, it seems XRMToolkit has yet supported this particular field on the proxy classes.
It will be really helpful for developers to be able to cater for this fields as it will be used more from now on.
This should be supported in v5.1.1 which was just released.

Hi there, it seems the release has some bugs still, the multi selection option field created are trying to set the "field_optionsetvalues" as an OptionSetValueCollection object, while the "field_optionsetvalues" are set as List<OptionSetValue> object instead of OptionSetValueCollection object.
We can get around the issue by setting the "field_optionsetvalues" as OptionSetValueCollection object on the get and set properties, but it will be a tedious process if we have multiple entities with the multi select option set fields.
Let me know if you require more information, I'll be glad to provide the screenshot detailing the issue that I'm referring to.
