Version Used: 3.4.0

Steps to Reproduce:

    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            try
            {
                // Creating the script
                var compiled = CSharpScript.Create<string>(@"return ""ciao"";");
                compiled.Compile();
                var runner = compiled.CreateDelegate();

                var result = runner().GetAwaiter().GetResult();

                Assert.AreEqual("ciao", result);
            }
            catch (Exception ex)
            {

            }
        }
    }

Expected Behavior: Test pass
