hi @sergiogonzalez, 

This is a pull request that @juliocamarero sent to me last week.

The last two commmits are just proposals. 

I've found it weird to create an object just for populate the service context. I've make more consistent with other APIs (so it coul be easier to mantain)

Maybe we can discuss with @marcellustavares
