Loading assemblies

PowerShell is .NET based but doesn’t load all available .NET assemblies when it starts.

Many people still use something  like

[System.Reflection.Assembly]::LoadWithPartialName(‘System.Windows.Forms’)

to load additional assemblies.  This is a hang over from PowerShell v1 when there wasn’t another way to perform the load.

The LoadWithPartialName method has been deprecated – https://msdn.microsoft.com/en-us/library/12xc5368(v=vs.110).aspx – and shouldn’t be used.

Your alternatives are:

Add-Type -AssemblyName System.Windows.Forms

or in PowerShell v5

using assembly System.Windows.Forms

using namespace System.Windows.Forms

can be used

Windows Server 2016 TP5 Cumulative Update

An update – KB 3157663 – should be installed BEFORE installing any roles, features or applications into a TP5 system.

Finding the update isn’t easy – no links from the TP5 pages and doesn’t show in search on Bing or if search microsoft.com

You can find it here:

https://support.microsoft.com/en-us/kb/3157663

Lets hope RTM is a bit more organised

New variables with the variable cmdlets

 

So you have some data in csv format:

column1 column2 column3 column4
——- ——- ——- ——-
a1      b1      c1      d1
a1      b2      c1      d1
a1      b3      c1      d1
a2      b3      c1      d1
a2      b4      c1      d1
a2      b3      c1      d1
a3      b5      c1      d1
a3      b6      c1      d1
a3      b7      c1      d1
a4      b5      c1      d1

In a variable $cd

You want colum1 and column2 in a new variable

Simplest way is probably

$new1 = $cd | select Column1, column2

The *-Variable cmdlets don’t get out much so I thought examples using them would be useful

You could also use the New-Variable cmdlet

New-Variable -Name new2 -Value ($cd | select Column1, column2)

Set-Variable also works

Set-Variable -Name new3 -Value ($cd | select Column1, column2)

PowerShell team announcements

A few announcements from the PowerShell Team that I’m catching up on.

The Microsoft.PowerShell.Archive module is now open source

https://blogs.msdn.microsoft.com/powershell/2016/04/25/the-archive-module-is-now-open-source/

The archive module was introduced in WMF 5.0. Its now available on the PowerShell Gallery for installation on WMF 4.0. Any future updates will be through the gallery. The version in the gallery is 1.0.1.0 as opposed to 1.0.0.0 that ships with WMF 5.0

You can now view the contents of files directly in the PowerShell gallery

A DSC toolkit for working with Amazon Web Services (AWS) is now available

https://blogs.msdn.microsoft.com/powershell/2016/04/20/aws-dsc-toolkit/

WMF 5.1 will become available when Windows Server 2016 ships

https://blogs.msdn.microsoft.com/powershell/2016/04/06/windows-management-framework-5-0-updates-and-wmf-5-1/

WMF 5.1 will contain the changes and bug fixes introduced since WMF 5.0 shipped. Many of these have been available on Windows Insider preview builds
