  "Connecting to remote server xxxx failed with the following error message :
  The WS-Management service cannot process the request. This user is allowed a maximum number of 18 concurrent shells,
  which has been exceeded. Close existing shells or raise the quota for this user.
  For more information, see the about_Remote_Troubleshooting Help topic."

  The above runtime error caused by a C# codes which was converted from VB codes, the VB codes work fine, but I got the above error after converted the codes to C#.

  Here is the VB Codes:

  Dim runspace As Runspace

  Dim powershell As PowerShell

  …..

  runspace = RunspaceFactory.CreateRunspace(connectionInfo)

  ….

  Try

  runspace.Open()

  powershell = powershell.Create()

  ...

  Finally

  'dispose the runspace and enable garbage collection

  runspace.Dispose()   //

  runspace = Nothing //

  'Finally dispose the powershell and set all variables to null to free up any resources

  powershell.Dispose()

  powershell = Nothing

  End Try

  **********************************************************

  This is C# Codes:

  Runspace runspace;

  PowerShell powershell = null;

  …..

  try {

     

  runspace.Open();

  powershell = PowerShell.Create();

  …..

  finally {

  //dispose the runspace and enable garbage collection

  runspace.Dispose();

  runspace = Nothing; //this code does not compile at all, but it compiles with the code of runspace = null; are they same?

  powershell.Dispose();

  powershell = Nothing; //this codes does not compile, but it is OK with powershell = null; are they same?

  }

  Basically, as the error message says, I need to release runspace to run powershell in C#,

  Appreciate any help, much appreciated!

  The problem is resolved by adding

  runspace.Close();
