Rust Libraries from C#: `LibraryImport`, `DllImport`, Handles, and Error Codes

A practical two-hour session on Rust Libraries from C#, focused on LibraryImport, DllImport, Handles, and Error Codes. The session treats Rust as a native component exposed through C-compatible boundaries, with attention to packaging, ownership, host-runtime tests, and failure handling.

Audience: entry-level and intermediate developers who want a practical engineering session, not a language tour.

Outcomes:

• Explain the practical boundaries of Rust Libraries from C#
• Apply LibraryImport in a small working example
• Apply DllImport in a small working example
• Apply Handles in a small working example

Format: two hours with a short framing walkthrough, a concrete example, discussion of tradeoffs, and a closing checklist for practice.
