What are the advantages of using the new [LibraryImport] source generator over traditional [DllImport] in .NET 7/8?

Traditional [DllImport] uses runtime IL stub generation and reflection marshaling. [LibraryImport] generates C# marshaling code at compile time! It is faster, fully AOT-compatible (NativeAOT), and allows you to inspect the exact marshaling code generated in your IDE.

It also eliminates the runtime JIT overhead on the first native function invocation. Highly recommended for any new P/Invoke code.
