To make larger workflows more manageable, workflows can now be searched by keyword. This feature is only available in Visual Studio; this feature is not available in a rehosted designer.
There are two kinds of searches available:. Properties of Activity objects, FlowNode objects, State objects, Transition objects, and other custom flow-control items. Quick Find is performed on the designer's ModelItem tree. Quick Find will not locate namespaces imported in the workflow definition. Keywords searched in workflows will match the actual content of the workflow files. The search results will be shown in Visual Studio Find Results view pane. Double-clicking the result item will navigate to the activity which contains the match in workflow designer.
NET Framework 4, variables and arguments could only be deleted in the designer using the keyboard. Starting with. Since a workflow or certain container activities such as NoPersistScope can only contain a single body activity, adding a second activity required the developer to delete the first activity, add a Sequence activity, and then add both activities to the sequence activity. The following screenshot shows the automatically created Sequence activity in the Body when a second WriteLine is dropped below the first.
To more easily navigate a large workflow in the designer, pan mode can be enabled, allowing the developer to click and drag to move the visible portion of the workflow, rather than needing to use the scroll bars. The button to activate pan mode is in the lower right corner of the designer. The following screenshot shows the pan button which is located at the bottom right corner of the workflow designer.
Multiple activities can be selected at one time, either by dragging a rectangle around them when pan mode is not enabled , or by holding down Ctrl and click the desired activities one by one. Multiple activity selections can also be dragged and dropped within the designer, and can also be interacted with using the context menu.
In order to make hierarchical workflows easier to navigate, components of a workflow are shown in a tree-style outline view.
The outline view is displayed in the Document Outline view. Clicking on a node in outline view will navigate to the corresponding activity in the workflow designer, and the outline view will be updated to show activities that are selected in the designer.
The following screenshot of the completed workflow from the Getting Started Tutorial shows the outline view with a sequential workflow. Prior to. Visual C projects now use C for expressions. A fully functional C expression editor is provided which capabilities such as grammar highlighting and intellisense.
C workflow projects created in previous versions that use Visual Basic expressions will continue to work. C expressions are validated at design-time.
Errors in C expressions will be marked with a red wavy underline. For more information about C expressions, see C Expressions. In a rehosted designer, some of the standard UI controls may not have meaning for a given workflow, and may be turned off. NET Framework 4, this customization is only supported by the shell bar at the bottom of the designer. The free Visual Studio Community can be used. SQL Server Express, a separate download, is also required.
The recommended operating system is Windows 7. See the course Setup Notes for details. Getting Started with WF 4.

Annotations In WF 4, the only place you can add text in the designer is the DisplayName section of an activity, which is a one-line text area at the top of the activity.
However, you wanted to be able to add comments or text in your activity designer to convey more than just the workflow definition such as adding a description of the behavior of a process step.
Figure 5 shows a workflow with and without annotations. Notice how you can now add descriptive information to any activity. With annotations, a printout of the designer can fully convey what the workflow is doing. Figure 5 A Workflow with and Without Annotations. You can display annotations as always visible or as a sticky note in the DisplayName bar of an activity.
Annotations are an opt-in feature and have no execution-time impact. To see annotations in action, take a look at the attached Annotations project in the companion code. For a hands-on experience, open a WF 4.
We listened. We added auto-connect, which enables automatically connecting a new activity to an existing activity in the designer.
And we added auto-insert, which lets you insert an activity between two existing activities by dropping the new activity on the connecting line. Figure 6 shows these features.
Figure 6 Auto-Connect and Auto-Insert. Large-Workflow Navigation In WF 4, when a workflow is larger than the screen, you move around using the vertical and horizontal scrollbars. You told us that moving around a large workflow this way is painful and limits your productivity.
You can enable Pan mode by clicking the Pan button in the designer. Panning is available as a general designer feature, so you can use it with any existing activity. To try panning, open any workflow in the designer, click the Pan button and enjoy panning around!
This gives you a very succinct and structured view of your workflow, enabling you to navigate large workflows more easily. Figure 7 Document Outline View of a Workflow. To try this feature, open a workflow in the designer, go to the View menu, select Other Windows and choose Document Outline. You made it clear how this affects your productivity and how important it was for us to provide this capability. To try this out, create a workflow project and start editing a workflow in the designer.
Add some activities and configure their properties. Now, search for a keyword using Visual Studio search. The search results should take you to the activity that matches the keyword. Auto-Surround with Sequence The WF 4 activity model supports composition at its very core; activities can be composed without restrictions.
Often, composite activities have a Body property that accepts just one activity instead of a set , which can be any other leaf or composite activity.
