obtaining the runtime type of a transparent proxy is not supported in this context

Question

I am new to selenium. While running (debugging) my selenium tests (in C#), I am getting "obtaining the runtime type of a transparent proxy is not supported in this context" and due to this none of the web elements are found.

I have used "Selenium.Support.PageObjects" & PageFactory to locate and initialize web elemements.

Can anyone help me out from this?

Below is snippet of my code:

using OpenQA.Selenium;
using OpenQA.Selenium.Support.PageObjects;

namespace TestFramework
{
    public class TestClass: TestBase
    {

        public TestClass(Driver driver): base(driver) { }

        [FindsBy(How = How.XPath, Using = "//div[@class='modal-footer']/button[@title='Yes']")]
        public IWebElement YesButton { get; set; }

        [FindsBy(How = How.XPath, Using = "//div[@class='modal-footer']/button[@title='No']")]
        public IWebElement NoButton { get; set; }


        public void ClickYesButton()
        {
        YesButton.Click();
        }
        public void ClickNoButton(int timeout = ConfigMT.DefaultTimeout)
        {
        NoButton.Click();
        }

    }
}

And TestBase class is:

using OpenQA.Selenium;
using OpenQA.Selenium.Support.PageObjects;
using OpenQA.Selenium.Support.UI;

namespace TestFramework
{

public class TestBase
{

    protected IWebDriver Driver { get; set; }

    public Page(Driver driver)
    {
        this.Driver = driver;
        PageFactory.InitElements(this.Driver, this);
    }

}
}

According to this thread at the bottom of this answer, this appears to be a bug in the VS debugger.

A workaround mentioned is to go to Debug>Options>Debugging>General and click the checkbox to Use the legacy C# and VB expressions evaluators

While this worked for me, you still won't be able to check methods or properties on the element if that's what you're trying to do unfortunately.
