This test passes:

        public void GenericMethodGroups()
            string program = @"using System;
class TestClass {
    void F<T>(T x) {}
    public void M() {
        System.Action<int> f;
        f = $F<int>$;
            var rr = Resolve<MethodGroupResolveResult>(program);
            Assert.That(rr.TypeArguments.Select(a => a.GetDefinition().Name).ToList(), Is.EqualTo(new[] { "Int32" }));

but this one fails:

        public void GenericMethodGroups2()
            string program = @"using System;
class TestClass {
    void F<T>(T x) {}
    public void M() {
        System.Action<int> f;
        f = $F$;
            var rr = Resolve<MethodGroupResolveResult>(program);
            Assert.That(rr.TypeArguments.Select(a => a.GetDefinition().Name).ToList(), Is.EqualTo(new[] { "Int32" }));

The only difference is that the generic argument is explicitly specified in the first case, but not in the second one. This may or may not be by design, but if it is by design then it would be a major improvement if the member ConversionResolveResult.Conversion.Method would contain the specialized method in this case.

This is by design; MethodGroupResolveResult.TypeArguments is documented to have only the explicitly provided type arguments.
I fixed Conversion.Method in 24d2d19, that should have been the specialized method.
