You did already mentioned to use nuget for ArrayPool instead of built-in array pool. BFE is compatible with NET4 But System.Buffers needs at least .NET 4.5 so i need to remove compatibility with NET4 and minimum version would be 4.5. What you do think? having support for NET4 is not critical, but i think better to keep compatibility with older dotnets.
Let discuss this in a separate issue.
