Array.LongLength property missing

[AArnott]

I'm porting libgit2sharp to portable and the lack of LongLength on arrays forces me to resort to Length, which will break the library in writing objects larger than 2GB in size. The wisdom of 2GB objects in git aside, this seems like a sad limitation if CoreCLR itself supports 64-bit processes.

FWIW, Presently, the runtime does not allow an array to contain more than int.MaxValue elements (and the actual limit is slightly smaller.)

So even if this was exposed, you could write the code you'd want, but you wouldn't get the behavior you desire.

Oh, interesting. Then in that case, removing a pointless API sounds good.
