WorkFlow Service Registration Tool (WFServicesReg.exe)

Workflow Services Registration tool (WFServicesReg.exe) is a stand-alone tool that can be used to add, remove, or repair the configuration elements for Windows Workflow Foundation (WF) services.


WFServicesReg.exe [-c | -r | -v | -m | -i]  


The tool can be found at the .NET Framework 3.5 installation location, specifically, %windir%\Microsoft.NET\Framework\v3.5, or at %windir%\Microsoft.NET\Framework64\v3.5 in 64-bit machines.

The following tables describe the options that can be used with the Workflow Services Registration tool (WFServicesReg.exe).

Option Description
/c Configures Windows Workflow Services. Used in install and repair scenarios.
/r Removes Windows Workflow Services Configuration.
/v Print verbose information (for either configuration or removal).
/m Enables MSI logging format.
/i Minimizes the window when the application runs.


The tool inspects the Web.config file and registers the following:

  • .NET Framework 3.5 reference assemblies.

  • A build provider for .xoml files.

  • HTTP handlers for .xoml and .rules files.

The tool inspects the Machine.config file and registers the following extensions:

  • behaviorExtensions

  • bindingElementExtensions

  • bindingExtensions

The tool also registers the following client metadata importers:

  • policyImporters

  • wsdlImporters

The tool also registers .xoml and .rules scriptmaps and handlers in the IIS metabase.

On Windows Server 2003 and Windows XP machines (IIS 5.1 and IIS 6.0), one set of .xoml and .rules scriptmaps are registered.

On 64-bit machines, the tool registers WOW mode scriptmaps if the Enable32BitAppOnWin64 switch is enabled, or native 64-bit scriptmaps if the Enable32BitAppOnWin64 switch is disabled.

On Windows Vista and Windows Server 2008 (IIS 7.0 and above) machines, two sets of .xoml and .rules handlers are registered: one for Integrated mode and one for Classic mode.

On 64-bit machines, three sets of handlers are registered (regardless of the state of the Enable32BitAppOnWin64 switch): one for Integrated mode, one for WOW Classic mode and one for native 64-bit Classic mode.


Unlike ServiceModelreg.exe, WFServicesReg.exe does not allow adding, removing, or repairing scriptmaps or handlers for a particular Web site. For a workaround to this issue, see the "Repairing the Scriptmaps" section.

Usage Scenarios

Installing IIS after .NET Framework 3.5 is installed

On a Windows Server 2003 machine, .NET Framework 3.5 is installed prior to IIS installation. Due to the unavailability of the IIS metabase, installation of .NET Framework 3.5 succeeds without installing .xoml and .rules scriptmaps.

After IIS is installed, you can use the WFServicesReg.exe tool with the /c switch to install these specific scriptmaps.

Repairing the Scriptmaps

Scriptmap deleted under Web Sites node

On a Windows Server 2003 machine, .xoml or .rules is accidentally deleted from the Web Sites node. This can be repaired by running the WFServicesReg.exe tool with the /c switch.

Scriptmap deleted under a particular Web site

On a Windows Server 2003 machine, .xoml or .rules is accidentally deleted from a particular Web site (for example, the Default Web Site) rather than from the Web Sites node.

To repair deleted handlers for a particular Web site, you should run "WFServicesReg.exe /r" to remove handlers from all Web sites, then run "WFServicesReg.exe /c" to create the appropriate handlers for all Web sites.

Configuring handlers after switching IIS mode

When IIS is in shared configuration mode and .NET Framework 3.5 is installed, the IIS metabase is configured under a shared location. If you switch IIS to non-shared configuration mode, the local metabase will not contain the required handlers. To configure the local metabase properly, you can either import the shared metabase to local, or run "WFServicesReg.exe /c", which configures the local metabase.
