The Microsoft.AspNet.Cryptography.Internal library does not load on Mono

[borgdylan]

This library is using some custom attribute that is not normally used causing a crash on Mono:

This appears to be the fault of DefaultDllImportSearchPathsAttribute which is not existent on Mono. If this where in the reference sources, The Mono team could add it.

This library will load as the latest Mono master.

Resolving as external, see https://bugzilla.xamarin.com/show_bug.cgi?id=27427.

Looking for some options here. The link says it is resolved, but not in the runtime. Also I can't find any reference to DefaultDllImportSearchPaths in master on Github (https://github.com/mono/mono/search?utf8=%E2%9C%93&q=DefaultDllImportSearchPaths).

There may be some implicit steps you guys know that I'm missing to get the fix the Mono team provided.

The commit to master was mono/mono@23603fe. There's no official redist for it yet since it's in master - check http://www.mono-project.com/docs/compiling-mono/ for instructions on how to build from source.

Thanks for the note. I was searching the repo for "DefaultDllImportSearchPaths" and couldn't find it. That commit link helped a bunch!
