Lawrence,

Take some advice from someone that has some experience with corperate IT politicts. I am a experienced VFP developer and have made the jump to C#. I would advise accepting the project if your boss understands that you will be learning C# as you go and you can not estimate the lenth of time it will take to complete the project. Let him know that you are willing to do this if that is what he wants. That way you are on his side and he will fell confortable with you. Now for the bad news it will take 4 to 5 times longer than you can do it in VFP. He will discover this through the development cycle and your not the bad guy and the company pays you to learn C# is this a great country or what.
