Missing name for ValueTuple in Linq

[sgkoishi]

Input code

using System.Linq;

var a = args.Select(v => (Name: v, Value: v))
    .OrderBy(kvp => kvp.Name)
    .First();

Erroneous output

(from v in args
    select (v, v) into c
    orderby c.Name
    select c).First()

The decompiled version is select (v, v) without the name (Name, Value) of the ValueTuple, thus the later orderby c.Name shows the error does not contain a definition for 'Name' ...
