Running async c # method in f # workflow

I am trying to get the code below to work in the F # async workflow, but I am getting the error "Unexpected character"} in the expression. I am new to both F # and async in general. What I miss here.

let someFunction (req : HttpRequestMesssage) a b = 

    // code
    async{
        let! readToProvider =
            req.Content.ReadAsMultipartAsync(provider)
            |> Async.AwaitIAsyncResult 

    } |> Async.RunSynchronously

    req.CreateResponse(HttpStatusCode.OK)

I am worried that my previous answer was not quite what you want. What I put just caused a compilation error. But one thing about this is that it does not start asynchronously. Task.Waitand Async.RunSynchronouslywill block the current thread until the operation is completed.

let someFunction (req : HttpRequestMesssage) a b = 
  async {
    let! readToProvider = (req.Content.ReadAsMultipartAsync provider) |> Async.AwaitIAsyncResult 
    return req.CreateResponse HttpStatusCode.OK
  }
