C# Interview tomorrow

Hello fellow programmers.

I know this doesn't have anything to do with code but I really need some advice. I have a .NET(C#) interview tomorrow for a junior vacancy. The problem I have is that all my experience is based on PHP. I have a good understanding of the fundamentals of OOP which is why I am looking to make the switch to C#. I have worked on my own at home, gone through a few books but I have nothing to show in terms of .NET projects. All my experience is in PHP. I have been working with PHP for 6 months but I have decided to make the switch now rather than later because I enjoy working with C# although I still have a lot to learn. I also feel like it offers better career prospects. How would you approach the interview if you were in my position?

Please help me.

Regards
