error FS9001: Unrecognized member of F# record type

[AlexPeret]

hi!

the snippet below makes the compiler throw this exception, when used in a library project.

Steps to reproduce:

1. at the library (.NET Framework) project

namespace Library1
...
[<JavaScript>]
module N1 =
  type T1 = {
      F1:string
  }
  with
      static member Create s =
          { F1 = s }
...

2. reference the library from a WebSharper 4 Client-Server Application and use the type

...
  let Test() =
    let vT1 = T1.Create ""
...

Note: If the type is moved to the web project, the compiler works fine.

It might be similar to this issue ##923

Solved. It should be a WebSharper 4 Library project and not a regular .NET Framework one.

If possible, it would be great to have a tip on warnings pointing to this requirement.
