Cannot load 'System.Security.Cryptography.Native.Apple' after recent CoreRT upgrade

[christianscheuer]

Hi all,

Has something been changed to the build system recently that means there's a chance the native parts of System.Security.Cryptography.Native.Apple don't get properly statically linked with the binary anymore?

Since our recent update to latest CoreRT, I get this when using any crypto functions:
System.DllNotFoundException: Unable to load DLL 'System.Security.Cryptography.Native.Apple': The specified module could not be found.

#33236 added lib prefix to the native libraries, but it was missed in number of places.

It can be worked around by changing this: https://github.com/dotnet/corert/blob/master/src/ILCompiler/src/ConfigurablePInvokePolicy.cs#L73 to check for both libSystem. and System.

Thank you, Jan. What would be the proper fix / should I log a bug in dotnet/runtime? (We prefer running our production builds on CoreRT master without branching if at all possible).

I have submitted dotnet/runtime#39717 to fix it in dotnet/runtime. It will take a while until we can pick up that fix (we need to do the runtimelab migration first). If you would like to have the workaround checked, feel free to submit PR once you verify that it works.

Keep this open to track removing the workaround.

Thank you so much for the quick help, Jan. We have our app running on Rosetta 2 / Big Sur ARM now, almost flawlessly :)
