Powershell remote .NET assembly deploy to GAC

If you need to deploy something to remote iis server by coping assemblies, here is a script.

To copy files you can use another post from this blog.

$s = New-PSSession -computerName someserverHostname.ru
Invoke-Command -Session $s -Scriptblock {
    $gacUtil = "${Env:ProgramFiles(x86)}\NETFX 4.0 Tools\gacutil.exe";
    $filesOnServer = Get-ChildItem C:\folderNameOnServer  -Recurse | Where-Object {$_.name -like '*.dll'}  | Select-Object fullname
    $filesOnServer  | % {
        & $gacUtil '/nologo' '/if' $_.fullname;
        $_.fullname;
    }
    iisreset;
;}
Remove-PSSession $s

Update Ready-to-use code

using System;
using System.Threading;

namespace Common
{
    public class Threading
    {
        public static void MarkThreadWith(string mark, object val)
        {
            LocalDataStoreSlot store = Thread.GetNamedDataSlot(mark);
            if (store == null)
            {
                store = Thread.AllocateNamedDataSlot(mark);
            }

            Thread.SetData(store, val);
        }

        public static bool CheckThreadFor(string mark, T val) where T : IEquatable
        {
            LocalDataStoreSlot store = Thread.GetNamedDataSlot(mark);
            if (store == null)
            {
                return false;
            }
            try
            {
                T newSlotData = (T)Thread.GetData(store);
                return newSlotData.Equals(val);
            }
            ///wrong thread
            catch (NullReferenceException)
            {
                return false;
            }
        }
    }

Masterpage location error while creating site from site template

Failed to instantiate file "default.master" from module

"DefaultMasterPage"

I found one possible reason for the error.

File "webtemp_SiteDefinition1.xml" contains something like that:

<?xml version="1.0" encoding="utf-8"?>

<Templates xmlns:ows="Microsoft SharePoint">

  <Template Name="ArchiveSiteDefinition"

            ID="10001">

    <Configuration ID="0"

                   Title="Archive Template Configuration Title"

                   Hidden="FALSE"

                   ImageUrl="/_layouts/images/CPVW.gif"

                   Description="Archive Template Configuration Description"

                   DisplayCategory="Content">

    </Configuration>

  </Template>

</Templates>

Bold text above can't contains white spaces, and maybe other symbols which nonalphanumeric.

Will work - "ArchiveSiteDefinition"

Will not work - "Archive SiteDefinition"

File "webtemp_SiteDefinition1.xml" must be located in folder with name ArchiveSiteDefinition in your studio project.
