Description Lopatkin Ilja 2013-09-11 04:02:25 UTC
Let's say we have a following code:

namespace Foo {
    public static class FooExtensions {
        static T Extension<T>(this object value) {
            return default(T);

namespace Bar {
    using System.Collections.Generic;

    public static class BarExtensions {
        public static IEnumerable<T> Extension<T>(this object value) {
            return new T[0];

namespace Bazz {
    using Foo;
    using Bar;

    public class Client {
        public void Method() {
            foreach (var foo in new object().Extension<int>())

In that case completion works fine and offers only the one Extension method which is the public method from BarExtensions. But at the same time resolver can't determine the type of foo variable because he thinks it's a method from FooExtensions and int type doesn't have GetEnumerator method.
