Is there a way to create a virtual network using C# and the Azure SDK/API?

Question

I don't see a clear way to create an Azure Virtual Network using the SDK.
I have all the methods to create the virtual network configuration, but no way to submit it:
IList<string> VirtualNetworkAddressPrefixes = new List<string>();
IList<string> LocalNetworkAddressPrefixes = new List<string>();
IList<NetworkListResponse.DnsServer> DNSServers = new List<NetworkListResponse.DnsServer>();
IList<NetworkListResponse.Subnet> Subnets = new List<NetworkListResponse.Subnet>();
NetworkListResponse.Gateway Gateway = new NetworkListResponse.Gateway();
IList<NetworkListResponse.LocalNetworkSite> LocalSites = new List<NetworkListResponse.LocalNetworkSite>();
IList<NetworkListResponse.Connection> Connections = new List<NetworkListResponse.Connection>();
VirtualNetworkAddressPrefixes.Add("a.b.c.d/cidr");
DNSServers.Add(new NetworkListResponse.DnsServer() { Name = "TestDNS1", Address = "a.b.c.d" });
Subnets.Add(new NetworkListResponse.Subnet() { Name = "Subnet-1", AddressPrefix = "a.b.c.d/cidr" });
Subnets.Add(new NetworkListResponse.Subnet() { Name = "GatewaySubnet", AddressPrefix = "a.b.c.d/cidr" });
Connections.Add(new NetworkListResponse.Connection() { Type = LocalNetworkConnectionType.IPSecurity });
LocalNetworkAddressPrefixes.Add("a.b.c.d/cidr");
LocalSites.Add(new NetworkListResponse.LocalNetworkSite()
Name = "On-Prem",
Connections = Connections,
VpnGatewayAddress = "a.b.c.d",
AddressSpace = new NetworkListResponse.AddressSpace() { AddressPrefixes = LocalNetworkAddressPrefixes }
Gateway.Sites = LocalSites;
Gateway.Profile = GatewayProfile.ExtraLarge;
NetworkManagementClient netMgmtClient = new NetworkManagementClient(CloudCredentials);
NetworkListResponse netlistresp = GlobalSettings.mainWindow.netMgmtClient.Networks.List();
netlistresp.VirtualNetworkSites
.Add(new NetworkListResponse.VirtualNetworkSite()
Name = "TestVirtualNetwork",
AddressSpace = new NetworkListResponse.AddressSpace() { AddressPrefixes = VirtualNetworkAddressPrefixes },
DnsServers = DNSServers,
Subnets = Subnets,
AffinityGroup = "East US",
Gateway = Gateway,
Label = "LabelValue"
I have also created the entire XML response and sent it to the NetworkManagementClient -> Networks.SetConfiguration() method, but it appears this command expects the virtual network to already be in existence. If anyone could give guidance, it would be
appreciated.

Hi,
As discuss above , we have to create the XML response  ,before that first you have to
GetConfiguration() details of existing virtual network. 
string.format("@<NetworkConfiguration xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://schemas.microsoft.com/ServiceHosting/2011/07/NetworkConfiguration'>
            <VirtualNetworkConfiguration>
            <Dns />
            <VirtualNetworkSites>
            <VirtualNetworkSite name=""{0}"" Location=""{1}"">
            <AddressSpace>
            <AddressPrefix>10.0.0.0/8</AddressPrefix>
            </AddressSpace>
            <Subnets>
            <Subnet name=""Subnet-2"">
            <AddressPrefix>10.0.0.0/11</AddressPrefix>
            </Subnet>
            </Subnets>
            </VirtualNetworkSite>",Networkname,location)+(@"<VirtualNetworkSite name=""demodsf1"" Location=""West Europe"">
        <AddressSpace>
          <AddressPrefix>10.0.0.0/8</AddressPrefix>
        </AddressSpace>
        <Subnets>
          <Subnet name=""Subnet-1"">
            <AddressPrefix>10.0.0.0/11</AddressPrefix>
          </Subnet>
        </Subnets>
      </VirtualNetworkSite>  </VirtualNetworkSites>
            </VirtualNetworkConfiguration>
            </NetworkConfiguration>")
you have to append the node for existing node with new values , i got it its adding new virtual network 
Best regards,
