In F# what is the difference between an internal method and a private method.
I have a feeling that they are implemented the same, but mean something different.

Internal is only available within the assembly it resides in. Public is available to any assembly referencing the one it resides in. If you can access the internal class from another assembly you either have "InternalsVisibleTo" set up, or you're not referencing the class you think you are.
protected internal: The type or member can be accessed by any code in the assembly in which it's declared, or from within a derived class in another assembly. private protected: The type or member can be accessed by types derived from the class that are declared within its containing assembly.
Internal access refers to giving full transparency to any necessary pre-release access within government, as deemed appropriate by the government.
The internal keyword is an access modifier for types and type members. We can declare a class as internal or its member as internal. Internal members are accessible only within files in the same assembly (. dll). In other words, access is limited exclusively to classes defined within the current project assembly.
An internal method can be accessed from any type (or function) in the same .NET assembly.
A private method can be accessed only from the type where it was declared.
Here is a simple snippet that shows the difference:
type A() =
member internal x.Foo = 1
type B() =
member private x.Foo = 1
let a = A()
let b = B()
a.Foo // Works fine (we're in the same project)
b.Foo // Error FS0491: 'Foo' is not defined
internal is the same as public, except that it is only visible inside the assembly it is delcared in. Private is only visible inside the declaring type.
