✅ Powershell SDK error on .Net 8

Hey, so I've been trying to invoke a powershell command using the Powershell SDK for .Net 8 but it seems to throw an error saying Windows.Web.dll wasn't found?

I have installed all the required packages

                using (PowerShell script = PowerShell.Create())
                {
                    script.AddScript("[Windows.Management.Deployment.PackageManager,Windows.Web,ContentType=WindowsRuntime]::new().FindPackages() | Where-Object { $_.IsFramework -eq $false -and $_.SignatureKind -ne 'System' } | Select-Object DisplayName, Logo, InstalledPath");
                    var results = script.Invoke();

                    foreach (var result in results)
                    {
                        string displayName = result.Properties["DisplayName"].Value.ToString();
                        string logo = result.Properties["Logo"].Value.ToString();
                        string installedPath = result.Properties["InstalledLocation"].Value.ToString();
                        string packageName = GetPackageName(installedPath);
                        string sizeInMB = GetPackageSize(installedPath);
                        apps.Add(new AppxPackages { DisplayName = displayName, AppIcon = logo, InstalledPath = installedPath, PackageName = packageName, PackageSize = sizeInMB });
                    }

that trick to load WinRT assemblies relies on runtime features that were removed in .NET 5 iirc

remi.nzOP•7mo ago

Sooo it means I can't use Powershell like that?

jcotton42•7mo ago

yes but also like, you could just use the WinRT stuff directly from C# no point in using PowerShell for this

reflectronic•7mo ago

i agree if you are using PowerShell just to call PackageManager there is absolutely no point in doing that. the APIs are easily usable from C#

reflectronic•7mo ago

if this is part of a script that you already have and it's complicated to untangle it will require some amount of work to use Windows.* APIs from it on .NET 8 it is still possible though i have never tried it

remi.nzOP•7mo ago

Oh alright

jcotton42•7mo ago

also I'm pretty sure Windows.Web isn't even the right assembly to load for that

remi.nzOP•7mo ago

Guess so too, that's why I was confused why is it throwing this error didn't find any solutions online so decided to ask here

reflectronic•7mo ago

in this case it does not matter because all Windows.* are redirected automatically to the right place. but, yes, it is not strictly correct
