There is no entry for `CopyMemory` exported from kernel32.dll as it is omitted from the following output: ``` dumpbin /exports C:\Windows\System32\kernel32.dll ``` The name we're looking for is `RtlCopyMemory`. This does not affect traditional .NET framework users as `CopyMemory` was special cased prior to .NET core ([source](https://github.com/dotnet/runtime/issues/12496#issuecomment-483442084)) The incorrect entry point will cause an `EntryPointNotFoundException` for NET core users (ref: https://github.com/nickbabcock/OhmGraphite/issues/214) There were a couple other entries in kernel32 that are missing: - CreateFile - LoadLibrary Both functions appear to have a `CreateFileA` and `LoadLibraryA` variant, but I do not know if those are appropriate.
