FS3186: An error occurred while reading the F# metadata node at position X in table 'itypars' of assembly .... The node had no matching declaration

(With F#4) If I compile an assembly with the following code:

namespace badlib

open System
open System.Windows.Input

type Interface2<'T> =
    inherit ICommand

type Class<'T>() =
    interface Interface2<'T> with
        [<CLIEvent>]
        member __.CanExecuteChanged : IEvent<EventHandler,EventArgs> = Event<EventHandler,EventArgs>().Publish
        member __.Execute(parameter : obj): unit = ()
        member __.CanExecute(parameter : obj): bool = false

Then referencing the assembly from another assembly produces the following build error:

FSC: warning FS3186: An error occurred while reading the F# metadata node at position 4 in table 'itypars' of assembly 'badlib, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. The node had no matching declaration. Please report this warning. You may need to recompile the F# assembly you are using.

After Visual Studio 15.7 update I get similar kind of

FSC: warning FS3186: An error occurred while reading the F# metadata node at position 1 in table
'itycons' of assembly '...'. The node had no matching declaration. Please report this warning. 
You may need to recompile the F# assembly you are using.
