This patch mitigates OS command injection in src/Servers/IIS/IntegrationTesting.IIS/src/IISExpressDeployer.cs by replacing ProcessStartInfo.Arguments with ProcessStartInfo.ArgumentList on line 193, ensuring that arguments containing potentially untrusted data from DeploymentParameters are properly escaped and passed as separate arguments to iisexpress.exe. However, patches could not be created for src/Tools/dotnet-getdocument/src/Exe.cs line 39 and src/Tools/Shared/SecretsHelpers/ProjectIdResolver.cs line 80 because these files already use ProcessStartInfo.ArgumentList instead of the vulnerable Arguments property.
