The following table shows some of the heuristics that the Spell Checker looks at when it scans a code document: What's in the codeĪlways check for both proper and common nouns In direct response to this feedback, the spell checker scans documents that are open. In response to that feedback, the spell checker only scans the document(s) that are active in the editor. Visual Studio checks the instance of Windows for the display language it's using, and if it's not "en-us", it uses that dictionary as well.Ĭ# and C++ also have additional dictonaries for keywords in those languages, which prevents words like ‘namespace’ or ‘alloc’ from being flagged as misspelled words.įeedback from early users of this feature informed us that developers only want to know about errors in the document they are currently working with. How does it work?īecause C#, C++, and Markdown all use English as the language for their keywords, Visual Studio typically uses the "English (United States)" or "en-us" dictionary for spell checking. After you choose to ignore a word, the spelling checker ignores it across all instances of Visual Studio. ![]() By choosing to ignore the issue, Visual Studio creates an exclusion.dic file in your AppData directory on your local machine. You can also choose to ignore the spelling issue. For identifiers in a C++ or a C# document, accepting a suggestion results in a Refactor/Rename that updates all instances of the identifier to make sure the code compiles. For strings and comments, choosing one of these suggestions results in a single, in-place replacement. If multiple dictionaries provide suggestions, Visual Studio groups its suggestions by dictionary. If any of the dictionaries provide spelling suggestions, Visual Studio displays them. When the context menu comes up, Visual Studio displays three options to handle a spelling issue. You can bring up the Quick Actions by using the keyboard shortcuts Ctrl+. When the caret is on a spelling error, the Quick Actions provide solutions for fixing the spelling mistakes. You can turn the spell checker off or on by using the Toggle Spell Checker button on the main toolbar, or by selecting Edit > Advanced > Toggle Spell Checker command from the menu bar. The feature even does a contextual rename when those misspellings are identifiers so that your code still compiles. ![]() Visual Studio also suggests alternate spellings and helps correct them. When the Spell Checker is enabled, Visual Studio marks any words that it detects as misspelled words. The Spell Checker is available for any C#, C++, or Markdown file. Now, with the Spell Checker feature-introduced in version 17.5-Visual Studio can even make sure your spelling is accurate. ![]() Many of the features in Visual Studio are designed to help you write the code you want, from making sure that your code compiles to helping you with code styling.
