PowerShell Core – How to install the Windows Compatibility Pack

July 3, 2018

First find the correct PowerShell Core Module

Find-Module -Name PSCoreWindowsCompat | ft -a 


As you can see it only runs on Windows x64 bit !


Keep in mind that this Windows Compatibility Pack is a Temporary solution from MS, and will not stay forever :


Windows Compatibility Pack for .NET Core is not a permanent solution which will stay in codebase forever. Intention of the pack is to build a temporary bridge, allowing adoption of .NET Core to a greater extend. However, in the long term the goal stays the same – replace outdated APIs and features of .NET with newer .NET Standard-compatible alternatives.

You can download it before installing using this command

Save-Module -Name PSCoreWindowsCompat -Repository PSGallery -Path C:\Temp\ -Force 


Or install it directly

Install-Module -Name PSCoreWindowsCompat -Repository PSGallery -Verbose -Force 


As you can see it needs Administrator Privileges



Import the Module PSCoreWindowsCompat

Import-Module -Name PSCoreWindowsCompat 


You have to use the DotNet Classes instead of Cmdlets.

For instance the Compatibility pack contains the System.DirectoryServices so you can script against AD.

Like this :

$dom = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()

$root = $dom.GetDirectoryEntry()

$search = [System.DirectoryServices.DirectorySearcher]$root

$search.Filter = "(&(objectclass=user)(objectcategory=user))"

$search.SizeLimit = 3000

$result = $search.FindAll()

foreach ($user in $result){



Compared to Windows PowerShell

Get-ADUser -Filter * | select DistinguishedName 


But it works perfectly … Smile



For .Net Core Applications see here :


Run this command :

dotnet add package Microsoft.Windows.Compatibility –version 2.0.0

Enjoy !

PowerShell Core – Running on Windows IoT using a RPI3

July 2, 2018

As mentioned on this post

I was planning to test PowerShell Core on Windows IoT running on an ARM platform using RPI3….

PS Core Version 6.x claims to be a cross platform Smile

It is still experimental as mentioned here :


So let’s take a look :

1. Download the correct ZIP


Windows IoT running on RPI3 is a 32bit version (if you are using the free version)


2. Open the ZIP

This contains all the modules needed to run on your RPI3


Extract and copy all files over to your destination RPI3 folder.



For example c:\pscore


3. Setup Remoting on RPI3

Run this command and see PS notes :

You’ll get an error message and will be disconnected from the device because it has to restart WinRM




# Be sure to use the -PowerShellHome parameter otherwise it'll try to create a new
# endpoint with Windows PowerShell 5.1
.\Install-PowerShellRemoting.ps1 -PowerShellHome .
# You'll get an error message and will be disconnected from the device because it has to restart WinRM


4. Connect to the PS Core on your RPI3

# Be sure to use the -Configuration parameter.  If you omit it, you will connect to Windows PowerShell 5.1
Enter-PSSession -ComputerName <deviceIp> -Credential Administrator -Configuration powershell.6.0.2



5. How to run Windows PowerShell modules in PowerShell Core

Run these 2 commands to get access to the Windows PS modules


Install-Module WindowsPSModulePath -Force -Scope CurrentUser 




Or this way for a custom module

Import-Module "C:\Program Files (x86)\AutoIt3\AutoItX\AutoItX.psd1"
Get-Command *au3*




6. Test PS Core on your RPI3


All runs as expected Smile


But keep in mind that not all functions are supported (yet)



Even if it says so see help Sad smile



Running PowerShell Core on Linux or Mac see here to get started :

PowerShell Core – Installing and Testing

July 2, 2018

PowerShell Core has reached version 6.1xxx at this moment …


Why do you need PS Core v6.1.x





How to install

Since PS Core is a cross platform distribution, just pick the one you need Smile



Download and run for a Windows 10 SxS installation




Select Open PS Core

or start is manually



In order to run PS Core you need to use the pwsh.exe commandline and not powershell.exe !

Check the PS Core version :

run pswh.exe –v


Or the famous command




PowerShell core does not have all the modules of the full blown version available.

But it has already a lot… run


it will list about 425 commands



If you need more :

Windows PowerShell Compatibility Pack

With the announcement of the Windows Compatibility Pack for .NET Core for .NET Core, PowerShell Core will regain some APIs that had been dropped in the transition to .NET Core.  This means we can re-enable some cmdlets that weren’t part of the PowerShell Core 6.0 release: WMI, EventLog, and PerfCounters.  In addition, some highly requested APIs will be available which means that some existing Windows PowerShell modules might just work in PowerShell Core 6.0.  This module will replace the WindowsPSModulePath module to add the Windows PowerShell $env:PSModulePath to PowerShell Core 6.0.  Finally, we can use this module to optionally add back some aliases that we removed from PowerShell Core 6.0 that exist in Windows PowerShell.

Example it allows you to run encrypted commands as well out of the box… Smile



For a full list of command line options run pwsh.exe /? (or –h or –help or …. Winking smile )

Most relevant are :

pwsh -NoExit -Command Get-Date



Some of the commands you need to run using Administrator privileges or you get this error :


pwsh -Command {Get-WinEvent -LogName security} or pwsh -command “& {Get-WinEvent -LogName security}”



You can run Windows PowerShell modules in PowerShell Core on Windows


Install-Module WindowsPSModulePath -Force -Scope CurrentUser 



Next episode I will test it the PS Core on an RPI3 running Windows IoT, see here


Windows Core IoT – ASP DotNet Core Razor Pages & SQLite & Web Service on a Raspberry PI3

May 28, 2018

Building a Web Server App using ASP .Net Core using a SQLite Database and a Web Service starts here using this example.


I gave it a little twist in order to get it to use SQLite and add a Web Service to it.

This means you need to follow page 1 of 8 from this Tutorial.

But make the necessary change mentioned below.

Requirements are that you have Dotnet Core installed.

And have the DB using EF Tools installed from NuGet

Creating the  .Net Razor App

1. Create a new blank RAZOR project

Create a new folder in your PC and run the command to create a new RAZOR project


Command : dotnet New Razor

This will create a new blank Razor project

2. Install the DB using EF Tools

Go to Nuget and look for this package


I used the version 2.1.0-rc1-final

Run this command :

dotnet add package Microsoft.EntityFrameworkCore.Tools –version 2.1.0-rc1-final

3. Add more packages needed

dotnet add package Microsoft.EntityFrameworkCore.Tools.DotNet –version 2.1.0-preview1-final

dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design –Version 2.0.0

dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Utils –Version 2.0.0

3. Add missing other packages

correct the project .Json package references

4. Add the missing code like to generate the DB

Or generate the code based on an existing DB using Scaffolding

Example : Create a Models folder. In the Models folder, create a class file named Student.cs

5. Create the xxxxContext DB context

In the Data folder create SchoolContext.cs

In Startup.cs add the missing references (Using xxx)

add the DB Context refence : services.AddEntityFrameworkSqlite().AddDbContext<SchoolContext>(); // Added

In the Data folder, create a new class file named DbInitializer.cs

6. Generate the View pages based on the model

Courses :

dotnet aspnet-codegenerator razorpage -m Course -dc SchoolContext -udl -outDir Pages\Courses –referenceScriptLibraries

Instructor :

dotnet aspnet-codegenerator razorpage -m Instructor -dc SchoolContext -udl -outDir Pages\Instructors –referenceScriptLibraries

7. Correct the ERRORS

When running the command in step 6 you will get ERRORS.

Globally change _context.Student to _context.Students (add an “s” to Student)


There are 7 occurrences found and updated. This is a bug and the hope to fix this bug in the next release.


8. BEFORE publishing add the following string in the program.cs and republish again.



9. Publish for RPI3 – ARM

Run this command :

dotnet publish -r win8-arm

10. Copy from Publish to your RPI3

Copy the Files from the PUBLISH folder to your RPI3.

ASPRazor -> C:\CoreIoT\ASPRazor\bin\Debug\netcoreapp2.0\win8-arm\ASPRazor.dll

ASPRazor -> C:\CoreIoT\ASPRazor\bin\Debug\netcoreapp2.0\win8-arm\publish\

Next MAKE SURE your FOLDER STRUCTURE on the RPI3, is exactly the same as it was on your PC before Publishing.

Next COPY the SQLite Database to your RPI3. Because this is NOT included when publishing using DotNet Core to win8Arm

11. Test the .Net Razor App on your RPI3

Connect to PowerShell Remote to your RPI3 and start the app.


Let access the database ?


Let’s add some data ?



Haleluja, this is fully functional and cross platform !!

Since you now have an SQLite DB running your can feed it with your RPI3 SENSOR data and read it out using the Web J

Adding a Web Service to the .Net Razor App

Next I will add it to the site to see we can access the data using a web service API.

Again instead of using the full blown Visual Studio we will only use the command line options.

Because we don’t want to install an elephant weight of software !


Actually Visual Studio uses all these commands in the background too … Winking smile

Run this command :

dotnet aspnet-codegenerator controller -api -name StudentAPIController -m Student -dc SchoolContext -udl -outDir Models\API –referenceScriptLibraries -f


see the result


You also have the option to generate XML instead of JSON


Check the result !!


This is how you you select ID 5

ID = 5


It contains GET / POST / PUT / DELETE methods !

Accessing the Web Service using PowerShell



$URL = "http://localhost:5000/api/StudentAPI"

$APIService = Invoke-RestMethod -Uri $URL

$APIService | select ID, lastName, firstMidName 

Enjoy !

Windows Core IoT – ASP DotNet Core Razor Pages on a Raspberry PI3

April 20, 2018

Continuing on based on my prior posts

.Net Core on RPI3

SQLite on RPI3

I am going to explain how to use Windows IoT and ASP .Net Core on a RPI3.

As of version 2.0 we now can create ASP Razor webpages in .NET Core.

Remember that in the past I made some post about Web Matrix

That is in fact the predecessor of ASP .Net Core. Read more here

How to use Razor Pages in ASP.NET Core 2.0

Start with installing the DotNet Core Template to begin with

Run command :

dotnet new Razor -n ASPnetCoreRazor -o C:\CoreIoT\ASPnetCoreRazor


Next Run the Template Application on your Windows PC.

Use command :

cd C:\CoreIoT\ASPnetCoreRazor

dotnet Run


Voila as simple as that Smile


Next Publish it for Windows IoT on a RPI3 Architecture

Run command :

dotnet publish -r win8-arm


Copy the files to your RPI3 from C:\CoreIoT\ASPnetCoreRazor\bin\Debug\netcoreapp2.0\win8-arm\publish


Connect to RPI3 using PowerShell remote session and start the ASPNetCoreRazor.exe Application


No connection … ? Sad smile



1. You need to open the Firewall Port 5000 on your RPI3 first.

Run command :

netsh advfirewall firewall add rule name=” ASPnetCoreRazor ” dir=in action=allow protocol=TCP localport=5000


2. Modify the Template Program.cs script

And add this line : .UseUrls(http://*:5000)


Publish again :

dotnet publish -r win8-arm


Copy the files back over to your RPI3 :


Next connect to RPI3 using PowerShell and start the app ….



Open the browser and go to : http://rpi3:5000


It runs as expected !! Smile

So now we know how to create RAZOR pages, the door is open to start experimenting with the RAZOR syntax.

As well as integrating SQLite database using the ASP .NetCore Razor Front End….

Enjoy !

Windows Core IoT – SQLite on a Raspberry PI3

April 15, 2018

As shown in the previous post you can run use Dotnet Core to compile apps for Windows IoT on a RPI3

See here how to get started with Dotnet Core

On the net you can find how to use Dotnet Core and SQLite :


But the example uses the Dotnet Core v1.0 Framework and run on Windows.

I will show here how to use the latest Dotnet Core v2.0 Framework and publish it for Windows ARM on RPI3 Winking smile

Run command Dotnet new console –n Sqlite –o C:\DotNetCoreApps\Sqlite

And check the result here :


Copy the program.cs as backup, and copy the program code from the site above into the program.cs file.

Change the namespace to SQLite (see-n SQLite in first command)


Change the sqlite.csproj file content by adding a few lines


Add these line :


<Project Sdk=”Microsoft.NET.Sdk”>

<PackageReference Include=”Microsoft.EntityFrameworkCore.Sqlite” Version=”2.0.2″ />
<PackageReference Include=”SQLitePCLRaw.bundle_green” Version=”1.1.10″ />

     <DotNetCliToolReference Include=”Microsoft.EntityFrameworkCore.Tools.DotNet” Version=”2.0.0″ />

Run command : dotnet Restore


As you can see it will use some Nuget packages as included in the sqlite.csproj file

Next run this command : dotnet publish -r win8-arm

And copy the files to your RPI3


Next open PowerShell do a remote session and run the .\SQLite.exe


When the SQLite DB doesn’t exist yet, it will be created automatically.


DotNet Core is really a cross-platform language !

It runs flawlessly on a RPI3 – ARM Architecture, by just re-using the same code base we use on a Windows machine Smile
