Visual Studio 2017 - Unable to initialize powershe

Day 1:

System: Windows 10
Microsoft Visual Studio Community 2017 
Version 15.5.5
VisualStudio.15.Release/15.5.5+27130.2026

I have a website project that is making use of the WindowsAzure.Storage NuGet package.

From within Visual Studio, I do the following:

Tools -> NuGet Package Manager -> Manage NuGet Packages for Solution ...

The system displays 2 updates are available:

Newtonsoft.Json v10.0.3 (currently installed v9.0.1)
WindowsAzure.Storage v9.0 (currently installed v8.7)

I select check the "Select all packages" checkbox and click the "Update" button.

FAIL (Never had this happen before) !!

Below is the output captured from Visual Studio:

Retrieving package 'WindowsAzure.Storage 9.0.0' from 'nuget.org'.
...
The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3007) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

Install failed. Rolling back...

Error List Window shows:

Failed to initialize the PowerShell host. If your PowerShell execution policy setting is set to AllSigned, open the Package Manager Console to initialize the host first.

Powershell output from: Get-ExecutionPolicy -List output:

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser    Unrestricted
 LocalMachine    Unrestricted

Is there a problem with the NuGet package itself or my system?

I have never had this issue before and after searching for a solution (none found so far) -- I am at the mercy of the NuGet / Visual Studio gods!

Thanks in advance.

======

Day 2: 8:00 am ...

Trying again... Lets see if we can get the Package Manager Console working...

Start Visual Studio (Community 2017)

TOOLS -> NuGet Package Manager -> Package Manager Console

Which results in the following being displayed:

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3007) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

The term 'Get-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Back to the drawing board! Will continue looking for a solution...

So, let's try Visual Studio Installer...

Launch Visual Studio Installer
Select "More" -> "Repair"

Which results in:

The dependent package cannot be found: Component.PowerShellTools.VS2017,version=3.0.585

I click on "View Log", which displays:

[1cb4:000a][2018-02-17T08:27:06] Error 0x80131500: The dependent package cannot be found: Component.PowerShellTools.VS2017,version=3.0.585

   at Microsoft.VisualStudio.Setup.Engine.PreChecks(String installationPath, Boolean isLayoutSet, Product product, ExecuteAction bootstrapperAction, ITelemetryOperation operation, IQuery query)
   at Microsoft.VisualStudio.Setup.Engine.Repair(CancellationToken token)

Ok - so somehow, my system has lost a dependent package (Component.PowerShellTools.VS2017) -- will try modify to see if I can add the package...

======

Day 2 - 10:15 am (still at it) - current state -- at wits end...

Microsoft Visual Studio Community 2017 
Version 15.5.6
VisualStudio.15.Release/15.5.6+27130.2027
Microsoft .NET Framework
Version 4.7.02556

I do the following:

TOOLS -> NuGet Package Manager -> Package Manager Console

Which results in the following being displayed:

If anyone (Microsoft) has a solution -- I would REALLY appreciate it !

======

Day 2: 3:09 pm ...

In one final (desperate) attempt, I Launched Visual Studio Installer

Click on "More" -> "Repair" ....

After a couple of hours Visual Studio was (re)installed:

Microsoft Visual Studio Community 2017 
Version 15.5.6
VisualStudio.15.Release/15.5.6+27130.2027
Microsoft .NET Framework
Version 4.7.02556

I then do the following (after lighting 12 candles and chanting "Bill-Bill-Bill")...

TOOLS -> NuGet Package Manager -> NuGet Manager Console

Result:

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3007) : Error in type "System.Security.AccessControl.ObjectSecurity": Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

The term 'Get-ExecutionPolicy' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

I am doomed -- I cannot use Visual Studio until this is fixed.

Day 3 - 7:49 am

I see my issue has been Triaged by MSFT at:

https://developercommunity.visualstudio.com/content/problem/199976/visual-studio-failed-to-initialize-the-powershell.html

Have also tried the "solutions" from these resources:

https://developercommunity.visualstudio.com/content/problem/154563/failed-to-initialize-the-powershell-host.html

https://docs.microsoft.com/en-us/nuget/release-notes/known-issues#opening-package-manager-console-fails-with-objectsecurity-exception

Unfortunately, none of the above have helped to correct this issue.

Most posts indicate a complete re-install of VS may be needed -- good grief!!

Hoping a solution will be found that DOES NOT REQUIRE A COMPLETE RE-INSTALL!

Day 3 - 1:54 pm

Gave up ...

UNINSTALLED Visual Studio. Shutdown (powered down system)
Startup (powered up system)
Downloaded Visual Studio installer from https://www.visualstudio.com/downloads/
Ran Disk Clean app as per installer instructions.
Shutdown (powered down system)
Startup (powered up system)
Ran Visual Studio 2017 Community Installer - success.
Start Visual Studio
TOOLS -> NuGet Package Manager -> Package Manager Console

So - not even a fresh installation of Visual Studio Community is solving this problem !!!!

======

Day 4 - 9:11 am

Late last night I opened a new issue at GitHub re PowerShell, see:

https://github.com/PowerShell/PowerShell/issues/6189

This morning, found a reply and took the suggestion of lzybkr and disabled Powershell V2; I posted the commands for disabling V2 on the GitHub post above.

The good news - I was able to update packages via NuGet again!

The bad news - If I start Visual Studio and then do:

TOOLS -> NuGet Package Manager -> Package Manager Console

The console window opens, but simply hangs with the following message:

Initializing Powershell host...

I STILL have NO idea WHAT is causing this behavior within Visual Studio; but after 4 days, I am just considering myself lucky that I can (once again) update NuGet packages and get back to work.

Although my "issue" of updating NuGet packages has (for the most part) been resolved, I still do not see this as a solution as the root cause of why Visual Studio / NuGet Package Manager Console cannot initialize the PowerShell host has NOT been resolved.

Should anyone find the root cause, please post your solution.

回答1:

The following finally solved the problem described above:

https://developercommunity.visualstudio.com/content/problem/199976/visual-studio-failed-to-initialize-the-powershell.html

回答2:

We have finally identified the root cause of the issue, and will be fixing in 15.8 release of Visual Studio.

For now, the possible workarounds for this are:

1) Install .NET 2.0 on your machine, which will install the System.Management.Automation Version=1.0.0

2) Use the binding redirect as suggested by some of the members of the community in devenv.exe.config:

<dependentAssembly>
   <assemblyIdentity name="System.Management.Automation" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
    <publisherPolicy apply="no" />
   </dependentAssembly>
