Can support net45? about k4os.compression.lz4 HOT 5 CLOSED

In general can be done as sources themselves do nt use any .NET 4.6 features, but I had problems with compatibility of dependencies: System.Memory and System.Buffers. There are some weird compilation errors when net 4.5 is added to the mix.

At the same time I remember having barriers like this myself: NET 3.5 compatibility as it was used by Unity (and using .NET 2.0 "engine"), NET 4.0 compatibility as this is last version supported by Windows XP. But .NET 4.5? Why it is a problem to upgrade?

Net46 is also only preinstalled only with windows 10...

Don't quote me on that, but:

I don't remember exactly, but it was something about using System.Runtime.CompilerServices.Unsafe (transient dependency of System.Memory?) which, when .NET 4.5 was added to the mix, was forced to use some version, which was causing run-time exceptions on .NET 4.6 (it was compiling just fine, it just didn't work).

I'll take another look.

Buffer.MemoryCopy was the problem. You can try now. 1.1.11
