It doesn't look like Material-UI's StyleProvider gets generated currently.
I can confirm it works with this implementation:
open Fable.Core
open Fable.Core.JsInterop
open Feliz
open Feliz.MaterialUI
[<AutoOpen;Erase>]
module MuiExtensions =
type Mui with
static member inline stylesProvider (props: IReactProperty list) = createElement (import "StylesProvider" "@material-ui/core/styles") (unbox props)
[<Erase>]
type stylesProvider =
static member inline injectFirst (value: bool) = Interop.mkAttr "injectFirst" value
static member inline children (elements: ReactElement list) = Interop.mkAttr "children" elements
