Step 1 – Activity Designers

Windows Workflow 4.0 Activity Designer assemblies must be installed into the GAC.

How to install Activity Designer assemblies into the GAC

1.       Download and unzip from

2.       Run MyDataSetup.msi and install to the default path

As an alternative from the Visual Studio Command Prompt, enter:

    gacutil /i


    For Example:

        gacutil /i C:\Projects\desktopWeb\MyData\Common\Activities\bin\Debug\MyData.Activities.dll

Step 2 - Managed Extensibility Framework (MEF) Extensions

Client Office workflows uses the Managed Extensibility Framework (MEF) for ModelItem expression builders. MEF allows expression builder extension plug-ins to be added by implementing certain interfaces and dropping the dll to an extensions folder. A future article will describe how to create a ModelItem expression builder plug-in. For the current code base, you will need to copy MyData.Extensions.dll into C:\Projects\desktopWeb\MyData\Extensions folder.

Note A future version will allow an extension dll to reside in the executing assembly folder.

Step 3 – SharePoint Requirements           

The SharePointUpdate activity and DocumentParts activity requires at least a SharePoint 2010 Foundation site.

SharePointUpdate activity requirements

  • The SharePointUpdate activity requires a list of items such as the Tasks list

DocumentParts activity requirements

  • The DocumentParts activity requires an Excel 2010 Workbook in a Document Library such as Shared Documents
