Cannot use Microsoft.FSharp.Compatability.Lazy methods on System.Lazy values


Using the PowerPack built against .NET 2.0 on a machine with .NET 4.0 installed (2.0/3.5 may or may not also be installed, doesn't matter):

r "FSharp.Powerpack.dll"

r "FSharp.PowerPack.Compatibility.dll"

let x = lazy(1)
Lazy.force x
will result in an error like:
error FS0193: The module/namespace 'System' from compilation unit 'FSharp.Core' did not contain the val '{MemberParentMangledName = Some "Lazy`1";
MemberIsOverride = false;
LogicalName = "get_Value";
TotalArgCount = 1;}'

Closing old suggestions since the PowerPack functionality in this drop of the PowerPack will not be expanded from this point.

Some requests for changes in functionality are also being closed for the same reason.

New functionality can be discussed in the versions of this code on GitHub:
and the Math.NET F# support, for Matrix functionality.

Seems to have only started since I installed .NET 4.5RC, and only on release compile, not on debug compile
