Why do I open this blog? I worked for more than 5.5 years as a .NET programmer in my country( in China ). I will work in usa starting from August, 2010. But this job is not in IT field. I really hope that I will have a chance to work for a good company in the usa as a .NET software engineer one day. For supervising myself whether I update the .NET knowledge every day or not during working in the usa, which field does not belong to an IT field, I open this blog. Meanwhile, I hope that this blog can also help you get something new or you can help me revise what I write wrong. Thanks.
