[BUG] "Unable to instrument module" caused by const field

[santisq]

Describe the bug

Having a const field on a PowerShell cmdlet causes the warning:

Unable to instrument module: ...../....MyModule.dll
Coverlet.Core.Exceptions.CecilAssemblyResolutionException: AssemblyResolutionException for 'System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Try to add true to test projects or pass '/p:CopyLocalLockFileAssemblies=true' option to the 'dotnet test' command-line

---> Mono.Cecil.AssemblyResolutionException: Failed to resolve assembly: 'System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

The field in question:

const WildcardOptions options = WildcardOptions.Compiled
    | WildcardOptions.CultureInvariant
    | WildcardOptions.IgnoreCase;

And, in turn, this also cause the coverage result to be all 0%:

To Reproduce

Moving the const in https://github.com/santisq/PSCompression/blob/main/src/PSCompression/Commands/GetZipEntryCommand.cs#L50-L52 as a field causes the warning. If changing it to a static readonly also solves the problem.

Steps to reproduce:

1. git clone 'https://github.com/santisq/PSCompression.git'
2. Open src\PSCompression\Commands\GetZipEntryCommand.cs and move the const WildcardOptions options from BeginProcessing method to a class field
3. Run .\build.ps1 -Task Build, Test

Expected behavior

No warnings when testing the project.

Actual behavior

Unable to instrument module: /home/runner/work/PSCompression/PSCompression/output/PSCompression/2.1.0/bin/netstandard2.0/PSCompression.dll

Configuration (please complete the following information):
Please provide more information on your .NET configuration:

• Which coverlet package and version was used? 6.0.3 - This issue also happened when testing different versions too.
• Which version of .NET is the code running on? I'm not sure if this question relates to the target framework I'm compiling for (netstandard2.0) or what .NET version PowerShell is running on (PowerShell 7 runs on .NET 8 and PowerShell 5.1 runs on .NET Framework 4)
• What OS and version, and what distro if applicable? This happened to me locally on Windows 10, and also in GitHub workers using windows-latest and ubuntu-latest.
• What is the architecture (x64, x86, ARM, ARM64)? x64
• Do you know whether it is specific to that configuration? Not sure

Additional context

As you can see this issue happens on the 3 workers (Linux PowerShell 7 / Windows PowerShell 7 / Windows PowerShell 5.1) when running tests: https://github.com/santisq/PSCompression/actions/runs/12713283173/job/35440961122 (Expand "Run Tests - ....").
