Convert a legacy (non-SDK-style) Visual Studio extension (VSIX) project to modern SDK-style csproj format. Use when the user asks how to modernize a VSIX csproj, convert a Visual Studio extension from old-style to SDK-style, simplify a VSIX project file, remove verbose MSBuild XML from an extension project, migrate a VSIX project to Microsoft.NET.Sdk, or update a Visual Studio extension project to use auto-globbing and modern NuGet PackageReferences. This skill is specifically for VSIX extension projects — not general class libraries, console apps, or other project types. Covers VSSDK and VSIX Community Toolkit (in-process) extensions targeting .NET Framework 4.8.
