    Hi daehyun,

    AX returns metadata for all extincting entities, so clients tries to generate classes for all of them in the same time, but there are duplicated types in metadata like ItemType and it fails with AmbiguousTypeBinding exception as you can notice.

    As a workaround you can delete all entities except one you need (and dependencies) and use this striped version of metadat for generation.

    Hello...

    The actual problem is in metadata. There is an Enum with name "ItemType" and also the Data Entity with same name "ItemType". Due to which the proxy file is not generated due to same name and giving the error.

    The solution will be changing the name of Data Entity "ItemType" to "ItemTypes"

    EntityType Name="ItemTypes"

    and also do not forget to change the name in Entity Set in container.

    EntitySet Name="ItemTypes" EntityType="Microsoft.Dynamics.DataEntities.ItemTypes"

    We have tested the same and it works fine.

    How did you figure out that "ItemType" causes this  problem?
