Assembly: IMetabaseObjectDescriptor;
The Assembly property determines the development environment unit or form that contains a custom class that implements model calculation method.
Executing the example requires the KONT_MODEL modeling container. The custom method template that contains two parameters is created in the container. The container also includes the USER_VAR and USER_VAR_FACTOR modeling variables that will be used as output and factor ones respectively.
Add links to the Metabase and Ms system assemblies.

After executing the example a model is created in the modeling container. A model will be calculated using the custom method that is implemented in the unit with the USER_MODEL identifier. The custom class is named My_Method. The output variable and one factor are added to the model.
