Nuget Command-line install is not launching Install/Init scripts - nuget

I was trying to use Nuget as a software deployment system (repository, versioning and delivery) - idea from Octopus. Previously I was packaging ASP.NET sites into a self-extracting RAR archives with a .CMD startup scripts embeded. Now I'm trying to use Nuget creating puckages during automated build. The issue is that the package installation scripts (tools\Install.ps1 or tools\Init.ps1) do not execute if the package is being installed using command line:
nuget.exe install <package_id> -OutputDirectory <install_folder> -source <local_repo>
Same scripts are able to execute when package installed from Visual Studio Package Manager or Console.
I do not see why this shouldn't be possible given omnipresence of PowerShell.
Am I missing something or this is behaviour by design? Will appreciate you help.
Yes, we did consider MSDeploy but we already have install scripts that do the same thing and give more control and we need some strong package management and repository for build artifacts (something that Java folks do with Maven).

As of today, the powershell scripts are not invoked from doing installations from command line.
One reason for this is that, in general, most of the install/init actions are tied to dte and the visual studio project and doesn't add much value to be able to run it from outside VS.
We have a backlog item for enabling support for exe based scripts too in addition to powershell.

Microsoft NuGet targets Error while building Project from Teamcity

I attempted in building the .NET Standard Library Project using .NET Framework 4.6.1 from Command prompt using MSBuild Commmand. I manage to succeed building the project from command prompt.
I tried the same MSBuild command to build the project from Teamcity Command line build step, but ended up getting the following error:
C:\Program Files (x86)\MSBuild\Microsoft\NuGet\Microsoft.NuGet.targets(140,5): error : The package Microsoft.NETCore.Portable.Compatibility
with version 1.0.1 could not be found in C:\Windows\system32\config\systemprofile\.nuget\packages\. Run a NuGet package restore to download the package.
I tried Restoring nuget.exe restore mysolution.sln but noting works.
Please help me to compile the solution from Teamcity command line step. Its strange to get compiled from command prompt but not from teamcity command line.
Looks like there is a known issue in NuGet when restoring packages using the LocalSystem account wherein the packages cannot be accessed under the C:\Windows\system32\config\systemprofile\.nuget\packages folder, even though account permissions should allow it (see this GH issue). The current recommended workaround is to use the NUGET_PACKAGES environment variable to specify another location for the packages (e.g. C:\NuGet\packages).

How to use paket from command line

I installed paket from nuget in Nuget Package Manager Console with:
Install-Package paket
I then tried to run paket convert-from-nuget. It stalled out on a user prompt (it wouldn't let me type into the package manager console). My next thought was to run it from command line, but how to do so is not documented.
Just putting paket convert-from-nuget into a standard dev command prompt results in an error saying "paket" is not recognized.
How do I run paket from the command line or powershell, and how do you specify which solution to work against?
The way to setup paket in your repository is as follow:
1 Download a release of paket.bootstrapper.exe
This is a lightweight utility which obtains and updates paket.exe, pick stable release from official release page:
https://github.com/fsprojects/Paket/releases
2 create a .paket folder
md .paket
3 put the downloaded bootstrapper in this folder and invoke it
cd .paket
paket.bootstrapper
now you have an up-to-date paket.exe ready to ease your handling of dependencies.
4 convert from nuget
cd ..
.paket\paket convert-from-nuget
Please checkout the https://github.com/fsprojects/Paket.VisualStudio also for Visual Studio plugin to help you authoring paket.dependencies and paket.references file
Please also join https://gitter.im/fsprojects/Paket if you have any questions.
The Chocolatey package modifies the PSModulePath envivornment variable. I've observed that sometimes that modification isn't picked up until the system is restarted (or at least not until the user logs out and back in again). In the meantime, you can import the module using:
Import-Module <path-to-packages>\Paket.PowerShell\Paket.PowerShell.psd1
The packages path is usually something like C:\Chocolatey\lib. OTOH, re-reading your question, are you referring to the Nuget inside of Visual Studio? If so, that downloads from NuGet.org and that pkg puts paket.exe in $(SolutionDir)\packages\Pakget.1.18.5\tools\paket.exe. Your version number may varying.
Unfortunately the fact that PowerShell V5 introduces Install-Package (which downloads from Chocolatey by default) is going to get a little confusing vis-a-vie the NuGet Package Manager Console's Install-Package in Visual Studio.

How do you query installed nuget packages with the command line interface?

I need to find the installed version of a package inside my CI build script using the nuget command line.
The "list" command returns ALL packages from the nuget.org feed as far as I can tell. I only want the locally installed packages.
I know how to do this with the VS nuget powershell console. Please do not answer "use get-package". I need to do it with the nuget.exe.
However if there's a way to use the nuget command from plain powershell outside of visual studio that would be acceptable.
nuget list -Source http://my.local.feed/ will list packages available in a local feed, and dir .\packages from within the top-level solution folder will show the packages installed under that location (where .\packages is the install location you have set for the solution).
From http://docs.nuget.org/docs/reference/command-line-reference#List_Command_Options and How do I specify the directory where NuGet packages are installed?

Executing C# code in Nuget Package

I am beginner in creating nuget packages. I created a nuget package which copies all files to solution explorer for now. I am trying to copy folder to users local folder where they have visual studio installed. Can I execute c# code while user installs nuget package on their visual studio solution? Any help would be highly appreciated.
You can add a powershell .ps1 script and set it to be executed while installing the nuget package. If Powershell wouldn't suffice ( most probably it would) and you absolutely want to have some piece of C# code run, just include the code in Powershell as described here: http://blogs.technet.com/b/stefan_gossner/archive/2010/05/07/using-csharp-c-code-in-powershell-scripts.aspx

Recommended approach to deploy VMware PowerCLI command line console application

PowerCLI with .NET has some dependencies on dll's that you get only when you install PowerCLI on each machine you want to run.
I have a console app with command line arguments, which when deployed using the usual method doesn't work because of the unmet dependencies...these assemblies are part of the GAC.
Clickonce deployment proved to be useless..it didnt recognize my arguments although I passed them as query params.
Finally, I installed VMware PowerCLI on this remote machine. Then ran the .exe and it worked. Is there a way to avoid installing PowerCLI and be able to include all the dependencies with my exe during deployment?
Depending on where exactly you want to deploy your console application, you may be out of luck. According to this page and the most relevant forum post I could find, the PowerCLI assemblies are not redistributable. Your best bet if you want to distribute this application outside your company is to use the Web Services SDK - a huge pain since you've already developed the app.
Assuming your application is for internal use only and you just want to deploy it on its destination server, you can do the following to reference the assemblies locally:
On the development machine, copy whichever PowerCLI .dlls you reference from the GAC (in %WINDIR%\assembly) to your solutions local directory.
Change your references in the project to point to the local versions of the .dlls.
Open the 'Properties' view for each of the references, and make sure 'Copy Local' is set to True.
Compile and deploy your console application (and it's coresident .dlls) to the target machine, it should reference them in the local directory and run without external dependencies.
Hope that helps!
You could also automate PowerCLI installation with a silent installation one-line Powershell script, if the problem is hiding the installation from the users.
Invoke-Expression ("cmd /c '$powerCLIexeFilePath'/S /VADDLOCAL=ALL /V/qn")
