Getting Started
The fastest way to understand TX Spell .NET for Windows Forms is to see it check a first document. The tutorials of Getting Started each end with a running application, and they differ in what the spell checker is connected to: the TX Text Control editor, the standard RichTextBox and TextBox, or no control at all.

Choose a Starting Point
| If your application uses | Start with | What you get |
|---|---|---|
| TX Text Control .NET for Windows Forms | TX Text Control | Spell checking as you type, a context menu and a dialog, connected in the designer without code |
A RichTextBox or TextBox | RichTextBox and TextBox | Misspelled words colored while the user types, and the spell check dialog, with a few event handlers |
| No control: a service, a batch job or a test | Checking Text in Code | The incorrect words of a string and their suggestions, from the TXSpell class |
The tutorials use C#, Visual Studio and .NET 8 or higher, except Create a .NET Framework Application, which uses the .NET Framework 4.8.
