Azure - Virtual Network does not exist when deploy to Cloud Service

I tried to add Cloud Service (classic) to Virtual Network (classic), but an error appears when I deploy (new portal - Update your deployment):

The update deployment operation failed for the domain 'developementtajgowebservicev1' in the deployment slot 'staging' with the name 'not working': 'The virtual network devvirtual-Network does not exist.'.

I added this code after Role tag into config file:

<NetworkConfiguration><VirtualNetworkSite name="devvirtual-Network"/><AddressAssignments><InstanceAddress roleName="WorkerRole1"><Subnets><Subnet name="Subnet-1"/></Subnets></InstanceAddress></AddressAssignments></NetworkConfiguration>

The virtual network with this name exist in same subscription.
