Breaking Changes
The What's New notes of versions 7.0 to 11.0 list no member of TX Spell .NET for WPF that was changed or removed, and none is marked obsolete. An upgrade therefore changes your project, not your code, plus a few behaviors worth testing. The table below gives the short answer for the version you come from; Breaking Changes in What's New describes each change in full.
By the Version You Come From
| You come from | Change in the project | Test |
|---|---|---|
| 10.0 | Target .NET 8 or higher, then update the package to 11.0.1 | Nothing new |
| 9.0 or 8.0 | Update the references, or switch to the package | Suggestions: since 10.0, dictionaries with replacement rules suggest correct forms for words typed without their accents or spelled phonetically |
| 7.0 | Update the references | The suggestions, and user dictionaries that start with the flags WORDCHARS, BREAK or ICONV, which TX Spell .NET applies since 8.0 |
| Earlier than 7.0 | Target the .NET Framework 4.5 or higher, then update the references | Everything above |
Changes That Require Work and Behavior Changes to Test have the details, and Deprecated APIs confirms that nothing is marked for removal.
