SSRS: After modify of a report data provider class

If you modify a report, on 2012 version, using on SSRS.
But after modify data provider class, modity report layour, do report modification, deploy and do an incremental CIL compilation you:

* can see the result, using dynamics, but only the layout of the report, and no data on new columns
* and you can see the report goes good on visual studio internal preview


The solution is to restart the SSRS Reporting Services service where it's installed, in my case on the same of AOS Machine.
