How to create NLBCluster from code (C#)

Question

Hi,
I am trying to create and configure NLB Cluster (Network Load Balancing Cluster) and add node from C# app. At this moment I'm trying to use WMI class MicrosoftNLB, but there are only administrative methods.
If i try to use this for instance
ManagementScope NLBScope = new ManagementScope("\\\\localhost\\root\\MSCluster");
ManagementPath mgmtPath = new ManagementPath("MSCluster_Cluster");
ObjectGetOptions objGetOptions = new ObjectGetOptions();
ManagementClass mgmtClass = new ManagementClass(NLBScope, mgmtPath, objGetOptions);
ManagementBaseObject inParams = mgmtClass.GetMethodParameters("CreateCluster");
but there is an exception "Invalid namespace" - and looks like smth is wront with that ManagmentPath.
I appreciate any help here.
Regards

There's no direct way to load x64 powershell into a C# process.  You could execute your code through x64 powershell from a x86 process with some rerouting of pipelines like is done in the sample code for the blog post I wrote about
routing powershell commands through other users' sessions in remote desktop services, but that's far more complicated than is necessary to accomplish what you're trying to do.
Your simpler options off the top of my head:
1.  Compile your app 64-bit or MSIL without 32-bit preferred checked if you have no 32-bit dependencies
2.  Use the WMI/CIM queries directly.
3.  Load the NetworkLoadBalancingCluster module manually in your powershell session by giving it the full path to the 32-bit version when loading it (if it exists - depending on your version of Powershell it has different searching capabilities if you
don't give it the full path)
