无法打开workflow的设计界面--缺'System.Workflow.ComponentModel.Compiler.ITypeProvider'

The service 'System.Workflow.ComponentModel.Compiler.ITypeProvider' must be installed for this operation to succeed

 

To fix this issue you have to edit your project file:

<Project>

<PropertyGroup>

            <ProjectTypeGuids> {14822709-B5A1-4724-98CA-57A101D1B079};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}ProjectTypeGuids>

Note: You will not encounter above error in ‘WSPBuider Project with Workflow' template.
