F# - POCO Class
- by ebb
Hey there! I'm trying to write a POCO class in proper F#... But something is wrong..
The C# code that I want to "translate" to proper F# is:
public class MyTest
{
[Key]
public int ID { get; set; }
public string Name { get; set; }
}
The closest I can come to the above code in F# is something like:
type Mytest() =
let mutable _id : int = 0;
let mutable _name : string = null;
[<KeyAttribute>]
member x.ID
with public get() : int = _id
and public set(value) = _id <- value
member x.Name
with public get() : string = _name
and public set value = _name <- value
However when I try to access the properties of the F# version it just returns a compile error saying
"Lookup on object of indeterminate type based on information prior to this program point. A type annotation may be needed prior to this program point to constrain the type of the object. This may allow the lookup to be resolved."
The code thats trying to get the property is a part of my Repository (I'm using EF Code First).
module Databasethings =
let GetEntries =
let ctx = new SevenContext()
let mydbset = ctx.Set<MyTest>()
let entries = mydbset.Select(fun item -> item.Name).ToList() // This line comes up with a compile error at "item.Name" (the compile error is written above)
entries
What the hell is going on?
Thanks in advance!
