Add Item to collection if item not exist

Tnx to Miroslav

So, this is extension methods that enables you to add item in collection if item does not exist already

 public static class CollectionsExtensions
    {
        /// 

        /// Adds item to collection if not exist already.
        /// 
        /// The type of the source.
        /// 
The collection.
        /// 
The element.
        /// 
The comparer.
        /// true if item is added to collection.
        public static bool AddIfNotExist(this ICollection collection, TSource element, Func comparer)
        {
            if (collection == null)
            {
                return false;
            }

            if (collection.Any(comparer))
            {
                return false;
            }
            else
            {
                collection.Add(element);
                return true;
            }
        }

        /// 

        /// Adds item to collection if not exist already.
        /// 
        /// The type of the source.
        /// 
The collection.
        /// 
The element.
        /// true if item is added to collection
        public static bool AddIfNotExist(this ICollection collection, TSource element)
        {
            if (collection == null)
            {
                return false;
            }

            if (collection.Contains(element))
            {
                return false;
            }
            else
            {
                collection.Add(element);
                return true;
            }
        }
    }

Powershell and Atomia Automation Server

First you need to create class library for CoreApiBasicAuth endpoint (use http://rkeithhill.wordpress.com/2006/11/08/calling-a-wcf-service-from-powershell/ as a help how to do this)

Using this library (for example CoreApiBasicAuth.dll) you can connect to Atomia Automation Server. In following example I created powershell script to list Windows Websites for specific account.

[Reflection.Assembly]::LoadFrom("c:\CoreApiBasicAuth.dll")
$wsHttpBinding = new-object System.ServiceModel.BasicHttpBinding
$wsHttpBinding.Security.Message.ClientCredentialType = [System.ServiceModel.BasicHttpMessageCredentialType]::UserName
$wsHttpBinding.Security.Mode = [System.ServiceModel.BasicHttpSecurityMode]::TransportWithMessageCredential
$endpoint = new-object System.ServiceModel.EndpointAddress("https://provisioning.test.com/CoreAPIBasicAuth.svc")

$coreAPI = new-object CoreApiClient($wsHttpBinding, $endpoint)
$coreAPI.ClientCredentials.UserName.set_UserName("Admin")
$coreAPI.ClientCredentials.UserName.set_Password("Admin")

$Acc = $coreAPI.GetAccount("123456")

#find websites for this account
$pageInfo = New-Object Atomia.Provisioning.Base.PagingInfo 
$strNames = @("CsWindowsWebsite")
$pageInfo.PageSize = 10
$pageInfo.PageNumber = 0
$res = $coreAPI.FindServicesByNamesForAccount($Acc.AccountId, $strNames, [ref] $pageInfo)
$sites = $res | ForEach-Object {$_.properties} | Where-Object {$_.Name -eq "Hostname"} | Select-Object propStringValue
Write-Output $sites

$coreAPI.Close()

Using powershell to get IIS worker process

Preparation:

• Enable execution of powershell scripts with command:

 Set-ExecutionPolicy RemoteSigned

• Import module for IIS

  import-module webadministration

Now you should be able to see new drive (IIS)

  get-psdrive

Now, to see worker process for specific pool you only need to execute:

   dir 'IIS:\AppPools\myAppPoolName\WorkerProcesses'

To list all process IDs use:

   dir IIS:\AppPools | Get-ChildItem | Get-ChildItem | Format-Table -AutoSize  processId, appPoolName

Export Certificates using Powershell

dir cert:\LocalMachine\My | Where-Object { $_.hasPrivateKey } | Foreach-Object { [system.IO.file]::WriteAllBytes("$home\$($_.SubjectName).pfx", ($_.Export('PFX', '')) ) }

ID4175: The issuer of the security token was not recognized...

This error is thrown by sts.
Obviously, it is error in  this section:

<issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<trustedIssuers>
  <add name="CN = test" thumbprint="12 34 56 78 89 45 45 45 45 45 44 44 44" />
</trustedIssuers>
</issuerNameRegistry>

At first look thubprint of certificate was OK. But when I open it in hex editor there was some characters that was not visible in text editor. I fix this and everything was OK. :)
