Remarks

Adding a Feature to the collection installs the Feature in the server farm, making it available for activation in its specified scope. Adding a Feature that has farm scope not only installs the Feature, but activates it within the farm.Warning: Using the SPFeatureDefinition constructor to create a Feature definition object is not supported, it returns a NullReferenceException if you attempt to implement members of an object created through the constructor.
