PowerShell running local from published Single Exe fails (without IncludeAllContentForSelfExtract)

Question

Exceptions when running a single exe file using PowerShell.

• Computer: Windows 10 (latest patches)
• PowerShell SDK: 7.2.4
• Application: Console net6.0

Code:

using System.Management.Automation;

Console.WriteLine("Test PowerShell Runner!");

var psInstance = PowerShell.Create();

psInstance.AddScript("(Get-Host).Name");

Console.WriteLine("Before Invoke.");
var returnObj = psInstance.Invoke();
Console.WriteLine("After Invoke.");

Console.WriteLine("Name: " + returnObj.First().BaseObject);

psInstance.Runspace?.Close();

Console.WriteLine("Was successful run");

Proj file:

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>
    <ItemGroup>
      <PackageReference Include="Microsoft.PowerShell.SDK" Version="7.2.4" />
    </ItemGroup>
</Project>

We can not have IncludeAllContentForSelfExtract (which will run successfully) due to security reasons, we want to keep all our code hidden as much as possible.

Also noting that this will run successfully in debug/run via your IDE, it is only the published version that fails.

We have tried including the powershell dll's in the published exe's path, but no impact.

Answer 1

the error output seems to be that AddScript method is expecting a path, so my guess is this line:

psInstance.AddScript("(Get-Host).Name");

should probably be:

psInstance.AddCommand("(Get-Host).Name");
