Powershell and C # Connection Broker

We have a problem using a C # script to configure a connection broker using Powershell.

When we import the module remotedesktopservices, since the session host role was installed and used earlier, then install the connection broker role, we must restart our script to get the correct output.

We can reproduce the behavior if we use Powershell directly.

These are the commands we call:

PS C:\Windows\system32> import-module servermanager
PS C:\Windows\system32> import-module remotedesktopservices
PS C:\Windows\system32> add-windowsfeature rds-connection-broker

Success Restart Needed Exit Code Feature Result
------- -------------- --------- --------------
True  No       Success  {Remotedesktop-ConnectionBroker}

PS C:\Windows\system32> ls rds:

  Directory: RDS:

Name              Type   CurrentValue     GP  PermissibleValues PermissibleOperations
----              ----   ------------     --  ----------------- ---------------------
RDSConfiguration        Container           -           Get-Item, Get-ChildItem
RemoteApp           Container           -           Get-Item, Get-ChildItem

PS C:\Windows\system32> import-module -force remotedesktopservices
PS C:\Windows\system32> ls rds:

  Directory: RDS:

Name              Type   CurrentValue     GP  PermissibleValues PermissibleOperations
----              ----   ------------     --  ----------------- ---------------------
RDSConfiguration        Container           -           Get-Item, Get-ChildItem
RemoteApp           Container           -           Get-Item, Get-ChildItem

After restarting Powershell or our program, the result looks (correctly) as follows:

PS C:\Windows\system32> ls rds:

  Directory: RDS:

Name              Type   CurrentValue     GP  PermissibleValues PermissibleOperations
----              ----   ------------     --  ----------------- ---------------------
RDSConfiguration        Container           -           Get-Item, Get-ChildItem
RDSFarms            Container           -           Get-Item, Get-ChildItem
RemoteApp           Container           -           Get-Item, Get-ChildItem
ConnectionBroker        Container           -           Get-Item, Get-ChildItem

We need this output without reloading our program. Is it possible to get a new version of Powershell in C #? "remove-module" and "import-module" did not help.

This is our C # code to get a Powershell space:

InitialSessionState iss = InitialSessionState.CreateDefault();
iss.ThrowOnRunspaceOpenError = true;
iss.ImportPSModule(initialRoles);

RemoteHost.powerShellRunspace = RunspaceFactory.CreateRunspace(iss);
RemoteHost.powerShellRunspace.Open();
