ListmyNumbers = new List { 2, 4, 6, 8 }; myNumbers.Should().OnlyContain(n => n % 2 == 0);
ListIn this code example, we create a new List of strings called `myStrings`, which contains three items. We then use the `Should` method to assert that the list contains the string "bar". Overall, Microsoft.VisualStudio.TestTools.UnitTesting provides C# developers with a range of useful testing tools, including the List Should methods, which can be used to ensure that code performs as expected.myStrings = new List { "foo", "bar", "baz" }; myStrings.Should().Contain("bar");
