Pipeline operator refuses to work

I can't understand why this

let data = 
    JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, string>>>(
         File.ReadAllText <| Path.Combine(myPath, "ejv.json"))

is ok, while this

let data = 
    JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, string>>> 
    <| File.ReadAllText
    <| Path.Combine(myPath, "ejv.json")

Gives me two errors, first is:

and second is:

What did I do wrong?

UPDATE @Patryk Ćwiek suggested a good edit, which seems to fix errors with types:

let data = JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, string>>> 
       << File.ReadAllText 
       <| Path.Combine(myPath, "ejv.json")

But it produces another puzzling message: Unexpected type arguments. Here's a screenshot:

I can easily get rid of it removing <Dictionary<string, Dictionary<string, string>>> but in this case my data is of object type, not a Dictionary. Can I somehow save type information an use pipelining as well?

SOLUTION

Thanks to @Patryk Ćwiek solution is as follows:

let d<'a>(s:string) = JsonConvert.DeserializeObject<'a>(s)
let data = 
    Path.Combine(myPath, "ejv.json") 
    |> File.ReadAllText 
    |> d<Dictionary<string, Dictionary<string, string>>> with 

I don't know why, but without that alias d it doesn't work.
