There are three steps to establishing a remote PowerShell session to your Exchange server:

Deciding which protocol to use for which service

The key distinguishing factor for our service will be found in the URL of the resource… If our URL looks like X, then it is a Y service, and you use Z tool to get to it

URL Service Type Cmdlet
Ends in .asmx or ?WSDL SOAP New-WebServiceProxy
Contains API, especially api/v2 REST Invoke-RESTMethod
Ends in .php PHP/Form Invoke-WebRequest

REST v. Soap, whats the difference?

Both REST and SOAP are simply methods of accessing information presented via web services. It will suffice to say that REST is now in vogue, and is generally believed to be easier to use and manage than SOAP, which tends to be a bit heavier on XML.

“A nice analogy for REST vs. SOAP is mailing a letter: with SOAP, you’re using an envelope; with REST, it’s a postcard. ”


Working with Web Services, SOAP, PHP and all the REST with PowerShell

PowerShell Core 6.0 is a new edition of PowerShell that is cross-platform (Windows, macOS, and Linux), open-source, and built for heterogeneous environments and the hybrid cloud.

The goal of PowerShell Core is to remain as compatible as possible with Windows PowerShell. PowerShell Core uses .NET Standard 2.0 to provide binary compatibility with existing .NET assemblies

Microsoft will not replace the standard PowerShell by PowerShell Core. Both will coexist side by side until further notice.

Now you can download and install Kali Linux directly from the Microsoft App Store on Windows 10 just like any other application:
