When used on user-defined types, the ~~~ operator resolves to op_LogicalNot rather than the expected op_OnesComplement. See dotnet/fsharp#457 (comment) for a workaround.
This should be fixed FSharp.Core. An attempt to fix this transparently failed, see dotnet/fsharp#458.
A plan to address this going forward is at dotnet/fsharp#458 (comment) but will require an update to FSharp.Core.

Approved in principle for F# 4.x+ at next FSharp.Core update. See ongoing discussion on github threads as well.

Note that this is, however, very hard to fix without breaking backwards compat.
