As my company has just been bought by a Microsoft partner, we are being forced to migrate to .NET. Could somebody out there who knows both CF and ASP explain why in the world you would choose ASP over Cold Fusion?

Thanks,

Having had very little exposure to Cold Fusion and a lot to ASP.NET, I would say, ASP.NET offers you much better separation between markup and code (using code behind), and it offers you a true object oriented programming model, which promotes reusability and component based development.

DISCLAIMER: I have a commerical interest in helping people migrate from ColdFusion to ASP.NET (see my signature, below). 

In my opinion, ASP.NET has the following advantages over ColdFusion (these aren't in any particular order):

• Better development tools. Visual Studio is a great IDE; there hasn't even been an official IDE for ColdFusion since 2001 when Macromedia discontinued CF Studio.
• Better performance and reliability.
• Lower cost. ASP.NET is free with Windows, while ColdFusion costs either $1300 (Standard Edition) or $7500 (Enterprise Edition) per server.
• Larger availibility of third-party add-ons (control libraries, test tools, etc.).
• Better integration with other Microsoft products (SQL Server, SharePoint, Exchange, etc.).
• It's easier to find and hire ASP.NET developers than ColdFusion developers.
