Custom field types are deployed at the server farm-level, using the Windows SharePoint Services Solution Deployment functionality.

The various pieces of a custom field type solution must be deployed to the following locations:

• The field type class must be deployed as a strong-named assembly to the global assembly cache.

• The field type definition XML file must be deployed to the same location as fldtypes.xml, the XML file that defines the base Windows SharePoint Services 3.0 field types:

  \program files\...\web server extensions\12\template\xml\

  Each field type definition must be included in a file named fldtypes*.xml. For example, if you have a field type definition for a field type that defines a Social Security Number, you might name the XML file fldtypes_ssn.xml.

• If you have specified a custom field editor user control for the field type, it must be deployed to the following location:

  \program files\...\web server extensions\12\template\controltemplates\

For more information about deploying your field type as a solution, see Solutions and Web Part Packages. For the specific steps to create a solution, see Creating a Solution.
