False positive NS1004 with assignment check on virtual property

[mariuszlip]

Hello, I received a warning for a check of "not assigned" property, it's related to #159 , but with Arg.Any<>() method
I managed to reproduce it in simpler project:

using System.Collections.Specialized;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using NSubstitute;
using NUnit.Framework;

namespace Example
{
    public class MyController : Controller
    {
        public void Save()
        {
        }
    }

    [TestFixture]
    public class UnitTest
    {
        private MyController TestedInstance { get; set; }

        [SetUp]
        public virtual void SetUp()
        {
            TestedInstance = new MyController();
        }

        [Test]
        public void ReturnEmptyOkResponseAfterSaving()
        {
            HttpResponseBase response = null;

            var controllerExecutionData = ConfigureTestedInstanceRequest((httpContext, requestContext) =>
            {
                response = httpContext.Response;

                requestContext.RouteData.Values["action"] = nameof(TestedInstance.Save);
            });

            (TestedInstance as IController).Execute(controllerExecutionData);

            response.DidNotReceive().StatusCode = Arg.Any<int>();
        }
        
        private RequestContext ConfigureTestedInstanceRequest(Action<HttpContextBase, RequestContext> configure)
        {
            var httpContextMock = Substitute.For<HttpContextBase>();
            httpContextMock.Request.Form.Returns(callInfo => Substitute.For<NameValueCollection>());
            httpContextMock.Request.QueryString.Returns(callInfo => Substitute.For<NameValueCollection>());
            httpContextMock.Request.Headers.Returns(callInfo => Substitute.For<NameValueCollection>());
            
            var routeDataMock = Substitute.For<RouteData>();

            var requestContextMock = Substitute.For<RequestContext>();
            requestContextMock.HttpContext.Returns(callInfo => httpContextMock);
            requestContextMock.RouteData.Returns(callInfo => routeDataMock);

            configure(httpContextMock, requestContextMock);

            return requestContextMock;
        }
    }
}

The warning I get is:
%userprofile%\Documents\Example\Example\UnitTest.cs(44,51,44,65): warning NS1004: Argument matcher used with a non-virtual member of a class.

Hi @mariuszlip
Thanks for reporting. As you mentioned, it is indeed related to #159. Fix is already in review, I hope to release new version this month
