Is it possible to force record type in F# when doing an assignment?

f#

Solution

let x = { myRec.x = "hello" }
// or
let x:myRec = { x = "hello" }
// or
let x = { x = "hello" } : myRec

Further details and examples are available in the documentation.

EDIT: Incorporated alternatives from comments.

Problem

To explain I think it is best with an example: ``` type myRec = {x: string} type myRec2 = {x: string} let x = {x = "hello"} let y(a: myRec) = a.x y(x);; y(x);; --^ error FS0001: This expression was expected to have type myRec but here has type myRec2 ``` So how do I force `x` to have the type `myRec` if both `myRec` and `myRec2` has the same signature?
