Many users want to implement some spelling check functionality in their applications. Writing own spelling libraries is a hard task, so, there is a built-in SpellCheck functionality in the .NET Framework. At this time, it works in Windows Presentation Foundation applications.

Tutorial Requirements:

• C# IDE (Visual Studio 2008 used in this tutorial)
• .NET Framework 3.5

So, here we go.

1. Create a new C# WPF Application:



2. Add a TextBox to your form:



In the XAML tab, add the following code between TextBox tags:



You can add the same code in the standard C# code window. Just enter:



Now, launch the application. You get something like this:



If you enter incorrect words, these are underlined in red. If you right-click the word, you get some spelling suggestions to correct.

Congratulations! The project is done.
