- ✔️ DO use `[LibraryImport]`, if possible, when targeting .NET 7+.
- There are cases when using `[DllImport]` is appropriate. A code analyzer with ID [SYSLIB1054](../../fundamentals/syslib-diagnostics/syslib1050-1069.md) tells you when that's the case.
- ✔️ DO define P/Invoke signatures that match the C export's argument count and use types that accurately represent each native type.
- ✔️ DO use the same naming and capitalization for your methods and parameters as the native method you want to call.
- ✔️ CONSIDER using the same naming and capitalization for constant values.
- ✔️ DO use .NET types that map closest to the native type. For example, in C#, use `uint` when the native type is `unsigned int`.
