Hosted PowerShell running .NET 4 Snap-In

Question

I created a .NET library and I want to create a GUI that calls the library via PowerShell. In order to call cmdlet I had to add an entry to Windows registry, because that library is compiled against .NET 4.

It works fine, but not for a PowerShell host in GUI. What can I do to set up PowerShell host to run a CLR 4 snap-in?

var rsConfig = RunspaceConfiguration.Create();
var myAssembly = new AssemblyConfigurationEntry("AssemblyName", "C:\...\Assembly.dll");
rsConfig.Assemblies.Append(myAssembly);
var runSpace = RunspaceFactory.CreateRunspace(rsConfig);
runSpace.Open();

using (var ps = PowerShell.Create()) {
    ps.Runspace = runSpace;
    ps.AddCommand("Get-MyCmdlet");
    ps.AddParameter("Param1");
    ps.AddParameter("Param2");
    foreach (var result in ps.Invoke()) { // CommandNotFoundException
        Debug.WriteLine(result.ToString());
    }
}

Problem solved. It was a little bit complicated. I wrote an article about it. Basically appending an assembly is a wrong approach. The easier way is register that assembly.
