How to access static functions from inside a class member function?

I have a unit test class:

type [<TestFixture>] BetTests()=
[<Test>]
  member x.HasGoodOddsTest() =
    let ret = HasGoodOdds 10.0
    Assert.IsFalse(ret, "Expected false");

and a static method defined outside of the class:

let HasGoodOdds odds = odds &gt;= 20.0

but I'm getting a compiler error: "The value or constructor 'HasGoodOdds' is not defined."

What's the syntax to get outside of the scope of the class? Thanks!

Is HasGoodOdds defined above the BetTests class? Is it defined in the same file?

It needs to be defined above it (in a prior file, or above it in this file - generally you can't reference entities in F# until after they are defined), and if the BetTests class is not defined in the same module, you need to either use a qualified name (as @Vitaliy says) or use an 'open' declaration to bring the namespace/module into scope.

This method should be defined in a module. Use Namespace.ModuleName.Method convention
