Running NUnit tests on Mono on Windows

I am new to Mono and I would like to be able to run tests on Mono. I created as simple unit test project in Visual Studio 2012 and compiled it against .NET 4.5.

using NUnit.Framework;
namespace ClassLibrary2.Tests
{
    [TestFixture]
    public class Class1Tests
    {
        [Test]
        public void MyTest()
        {
            var a = "andsdsaj";
            var b = "fjkfjkdjfk";

            Assert.AreEqual(a, b);
        }
    }
}

Then I try to execute it from the Mono Command Prompt:

C:\Program Files (x86)\Mono>nunit-console "C:\Users\boris.m\Documents\Visual Studio 2012\Projects\ClassLibrary2.Tests\bin\Debug\ClassLibrary2.Tests.dll"

I am getting the following error:

C:\Program Files (x86)\Mono>nunit-console "C:\Users\boris.m\Documents\Visual Stu
dio 2012\Projects\ClassLibrary2.Tests\bin\Debug\ClassLibrary2.Tests.dll"
