# C1Excel Task-Based Help

## Content



The task-based help assumes that you are familiar with programming in Visual Studio. By following the steps outlined in the Help, you will be able to create projects demonstrating a variety of **Excel for WPF** and **Silverlight** features and get a good sense of what **Excel for WPF** and **Silverlight** can do.

Each task-based help topic also assumes that you have created a new .NET project and added the appropriate directives (`using C1.C1Excel;` for C#; `Imports C1.C1Excel` for Visual Basic) to the code.
