- ✔️ 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`.
- ✔️ DO prefer expressing higher level native types using .NET structs rather than classes.
- ✔️ DO prefer using function pointers, as opposed to `Delegate` types, when passing callbacks to unmanaged functions in C#.
- ✔️ DO prefer using function pointers and [`UnmanagedCallersOnlyAttribute`](xref:System.Runtime.InteropServices.UnmanagedCallersOnlyAttribute), as opposed to `Delegate` types, when passing callbacks to unmanaged functions in C#. For more information, see the <xref:System.Runtime.InteropServices.Marshal.Marshal.GetFunctionPointerForDelegate>.
- ✔️ DO use `[In]` and `[Out]` attributes on array parameters.
- ✔️ DO only use `[In]` and `[Out]` attributes on other types when the behavior you want differs from the default behavior.
- ✔️ CONSIDER using <xref:System.Buffers.ArrayPool%601?displayProperty=nameWithType> to pool your native array buffers.
