Why is this an issue?

Platform-dependent types have different sizes on different target platforms, while platform-independent types have the same size on all target platforms. Casts between platform-dependent and platform-independent types will have different behaviours on different target platforms, and should be removed.

Platform-dependent types include:

• All pointer-based types, including strings, arrays, classes, and interfaces
• NativeInt and NativeUint

How to fix it

Refactor the code so that platform-dependent and platform-independent types are not cast to each other.
