.SYNOPSIS
    Fixes StyleCop warnings in C# files.

.DESCRIPTION
    Automatically fixes common StyleCop warnings:
    - SA1413: Adds trailing commas to multi-line initializers
    - SA1515: Adds blank lines before single-line comments
    - SA1518: Ensures files end with single newline
    
.PARAMETER Path
    The root path to search for C# files. Defaults to "MediaBrowser.Model"

.PARAMETER DryRun
    If specified, shows what would be changed without actually modifying files

.EXAMPLE
    .\FixStyleCopWarnings.ps1 -DryRun
