Localizing VSIX Packages

Localizing VSIX Packages

 

You can localize a VSIX package by creating an Extension.vsixlangpack file for each target language and then putting them in the correct folder. When a localized package is installed, the localized name of the extension is displayed together with a localized description. If you supply a localized license file, or a URL that points to localized information, they are also displayed.

If the content your VSIX package includes a VSPackage that adds menu commands or other UI, see Localizing Menu Commands for information about localizing the new UI elements.

When a user installs an extension, Extensions and Updates checks the top level of the VSIX package for a folder whose name matches the Visual Studio locale of the target computer. If Extensions and Updates finds a .vsixlangpack file in the folder, it substitutes the localized values in that file for the corresponding values in the .vsixmanifest file. These values are displayed when the extension is being installed. The following example shows the directory structure for a VSIX package that is localized into Spanish (es-ES) and French (fr-FR).

    MyExtension.dll

        Extension.vsixmanifest

        [Content_Types].xml

        es-ES

            Extension.vsixlangpack

        fr-FR

            Extension.vsixlangpack

System_CAPS_noteNote

The VSIX-supported project templates in the Visual Studio SDK generate a VSIX manifest and name it source.extension.vsixmanifest. When Visual Studio builds the project, it copies the content of that file into Extension.VsixManifest in the VSIX package.

The Extension.vsixlangpack file follows the VSIX Language Pack Schema. This schema has a VSIXLanguagePack root element, and these four child elements: LocalizedName, LocalizedDescription, MoreInfoURL, and License. These child elements correspond to the Name, Description, MoreInfoURL, and License child elements of the Identifier element of the Extension.vsixmanifest file.

When you create a vsixlangpack file, you must set the Include in Vsix property to true. Otherwise, the localized installation text will be ignored.

To set the Include in Vsix property

  1. In Solution Explorer, right-click the Extension.vsixlangpack file, and then click Properties.

  2. In the Property Grid, click Include in Vsix, and set its value to true.

The following example shows relevant portions of an Extension.vsixmanifest file, together with the corresponding Extension.vsixlangpack file for Spanish. The values from the language pack replace the values from the manifest if the Visual Studio locale of the target computer is set to Spanish.
