Pull request overview
This PR updates the C# language version from 13.0 to preview across the PowerShell repository. This enables the use of C# preview language features in the codebase. The change is applied to common property files that are imported by most projects, as well as specific projects that explicitly set their own LangVersion.
Changes:
- Updated LangVersion from
13.0topreviewin PowerShell.Common.props, Test.Common.props, and several individual project files - Renamed variable from
fieldtomatchin BasicHtmlWebResponseObject.Common.cs to avoid conflict with C# 13'sfieldcontextual keyword
