Remarks
When to Call
Apply the RegisterEditorExtensionAttribute attribute to classes implementing an editor factory
Basic Usage
This attribute associates a file extension with a given editor factory. The file extension should include the prefixing ".".
This attribute is used only for registration purposes and does not affect runtime behavior. It should be placed on a package class.
Each editor factory also has an associated priority. For a given file extension, the editors with the highest priority number are given the chance to read a file first. If the editor fails to read the file, the remaining editors are used in order of priority. To use RegisterEditorExtensionAttribute, place it on a package class, such as Package or IVsPackage.
Registry Entries
The following registry entry is created by RegisterEditorExtensionAttribute:
<VSROOT>\Editors\{FactoryGuid}\Extensions\Extension=Priority
Note The GUIDS for the Visual C# and Visual Basic project types are:
C#: {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}
VB: {F184B08F-C81C-45F6-A57F-5ABD9991F28F}
Samples
You can find implementations of RegisterEditorExtensionAttribute in the managed samples. The standard location for this and all other attributes used for automatic registration is adjacent to the implementation of Package in VsPkg.cs, VsPkg.vb, or VsPkg.cpp, depending on the language used in the sample.
Note
C# automatically appends the word Attribute to the name of any attribute class. In C# code, refer to this attribute as RegisterEditorExtension.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
