Ignored Classifications

This category lets you exclude specific classifications of text from being spell checked by content/file type. This is more generic than the C#/C-Style language category options and can be applied to any language or file type for which Visual Studio or the solution/project spell checker can classify text.

The options for this category are divided into two sections: one for Visual Studio text editor classifications and one for solution/project spell checking classifications. Classifications can be ignored in either category or both as you see fit. See the sections below for more information.

For non-global settings, an option is available to inherit the ignored classifications from configurations above the current one. If enabled, any additional ignored classifications in the current configuration are added to those. If disabled, the settings in the current configuration will replace the inherited list of ignored classifications. If not inherited and the list is left empty, it effectively clears the list of ignored classifications.

Visual Studio Classifications

Visual Studio text editor classifications are determined as needed. When first opened, this page will only display content types and classifications that it knows about from the current configuration file. Select this configuration category page to enable classification tracking, open some files containing the content that you want to exclude, wait a few seconds to allow the spell checker to finish processing the files, and return to the configuration editor. Click the Refresh Content Types button to make the new content types and related classifications available in the content type combo box and classification list box.

Note Note

You will not see any classifications for C# files nor will you see any classifications for other C-style languages if you have enabled applying the C# options to all C-Style languages. Use the C# options to control the spell checked classifications for those languages when it is enabled. If the option is disabled, you will see classifications for non-C# C-style languages.

Select a content type from the combo box and the related spell checked classifications that have been seen in the files that you opened will be displayed in the list box to the right of it. Check the box next to each classification that you want to exclude or uncheck them to include them again. The classifications shown are the internal ones from the language classifiers and vary from language to language. Many are self-explanatory but others may not be. You may need to experiment with the classifications to determine which ones to use to exclude the elements you are interested in ignoring.

Solution/Project Spell Check Classifications

Solution/project spell checking uses a separate process with a fixed set of possible classifications. You can exclude classifications by file type or by individual file extension when performing solution/project spell checking. Extension settings will override their corresponding file type settings if both are present in the list of classifications to ignore. Note that not all classifiers use the full set of classifications.

To add exclusions, select a file type from the combo box. When selected, the related set of file extensions can be found in the extension combo box. The "All" option for file extension covers all extensions for the selected file type. Click the Add button to add the selected file type or extension to the ignored set. Note that many file types are quite similar but use different rules to classify their elements (i.e. XML and XAML). If you want to exclude an element common to both such as XML comments, you will need to add each file type and exclude the related classification from both types. Once added, the classifications can be found in the list box on the right. Check the box next to each classification that you want to exclude or uncheck them to include them again.

Unlike the Visual Studio classifications, the solution/project spell checker uses a fixed set of well-known classification types. The full set is always displayed for each file type or extension but not all are used by each. The classification types are as follows:

Classification Type



An XML/HTML element attribute value


Delimited comments in code, format varies by language (/* Comments */)


The inner text of an XML/HTML element


An interpolated string literal in code ($"Age: {age}")


A normal string literal in code, format varies by language ("Some text" or 'SQL string literal')


Run of the mill plain text. This is typically only seen for actual plain text files and files not recognized as any other known file type.


A quadruple slash comment in code, typically used to comment out code so that it is not included when spell checking, format varies by language (//// Comment)


A region directive in code (#region Private data members)


A single-line comment in code, format varies by language (// Single-line comment)


A verbatim/raw string literal in code (@"C:\Path\File.txt" or R"(C:\Path\File.txt)")


The inner text of an XML comments element in code (<summary>Member summary</summary>)


XML documentation comments in code. This is a general designation to classify an entire section as XML documentation comments in code. If excluded, the entire set of XML documentation will be omitted from spell checking. If not excluded, it will typically be classified further into attribute values if the attribute is spell checked and XML comments inner text.


A <![CDATA[....]]> section in an XML file


An XML/HTML file comment (<!-- Comments -->)
