RSRP-286957: extract method inside linq select fails to determine right return type (parser problem?)

This might just be a limitation caused by the generic type inference, but off-hand it seems like R# has sufficient information to determine it (although I'm certainly not looking at the more general case).

In the below code (simplified repro of the situation I actually hit, of course :) when doing extract method on SquareNumber (does not yet exist), while the VS/C# compiler isn't able to infer the generic type params e 'exto Select (causing the compiler error tooltip on the 'generator' return and the 'Select' method call), it seems like there's enough info there for R# to determine that the return value for SquareNumber is likely to be 'int'.

Since the 'extract method' just puts in a default return value (in the current behavior, of 'object'), then having it choose 'int' as a better return value doesn't have to be right 100% of the time (the user can still change the return value as part of the 'live template') but it would be a better user experience to default to 'int' instead. :)

using System;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        var results = Foo();
        Console.WriteLine(results);
    }

    static int[] Foo()
    {
        var generator =
            Enumerable.Range(1, 10)
                .Select(i => SquareNumber(i))
                .ToArray();

        return generator;
    }
}
