Using Tesseract ocr in C# Project

I have downloaded tesseract from Here. When i tried to add the dll file to visual studio 2012, its showing error that its not an valid assembly. Can anyone suggest me some other dll file of ocr and sample coding. I've tried many websites but i dint found any good one. Then i found this dll file tessrect and used the following code 

string path = @"C:\pic\mytext.jpg";
Bitmap image = new Bitmap(path);
Tesseract ocr = new Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789"); // If digit only
ocr.Init(@"C:\tessdata\", "eng", false); // To use correct tessdata
List<tessnet2.Word> result = ocr.DoOCR(image, Rectangle.Empty);
foreach (tessnet2.Word word in result)
Console.WriteLine("{0} : {1}", word.Confidence, word.Text);

But visual studio throwing error that its not valid assembly. can anyone help me in this ...

EDIT : Frameworks in properties folder only Thanks n advance

I tried to use Tesseract .NET wrapper. It has more pleasent syntax:

using (var engine = new TesseractEngine(pathToLangFolder, "eng", EngineMode.Default))
{
    // have to load Pix via a bitmap since Pix doesn't support loading a stream.
    using (var image = new Bitmap(fileName))
    {
        using (var pix = PixConverter.ToPix(image))
        {
            using (var page = engine.Process(pix))
            {
                Console.WriteLine(page.GetMeanConfidence() + " : " + page.GetText());
            }
        }
    }
}
