Could anyone kindly let me know how I can create a new FeatureClass as output from the IGPParameter. I have a requirement where I need to output a feature class with geometries. They are calcuated based on input ids. The source for the data is not part of the Input parameters.
From what I have looked into so far IGPParameter3 has a property for "Schema" which can be used to define a complete structure for the output. Below is the code I have in the ParameterInfo property.
