Since 2010 I have created hundreds of Excel financial, actuarial and tax functions with the .NET 4 framework. Most of these functions can relatively easy be used in a ASP.NET website, although their speed is not as fast as when used in Excel. In the near future I will add some of these functions to my site. I'll start now with a simple 'name' application:
Enter your first name
Enter your last name
I use this page also for ClickOnce testing purposes. Do not install anything from this page, as it may result in errors. The buttons above however are safe.
