ok sorry Onno van Knotsenburg.
the version of qlik is 2.2.4.
The reload must start from code and after I have to schedule with windows.
I copy this script in visual studio and i add the riferment i run the script but does not work.
I download this files: QlikSense.NetSDK_220.127.116.11
my Italian is not so good but from what I can guess you are missing the refences to the .Net SDK.
You can download the SDK from nuget, the best way is to right click yor solution an select "Manage NuGet Packages for Solution...". In the seach box type Qlik Sense NetSDK, select QlikSense.NETSDK and select you version and "Install". More examples can be found here Download code samples ‒ Qlik Sense
