To add a reference to the DataModel assemblies, perform the following:
In the Solution Explorer window, right-click References, and then select Add Reference....
The Reference Manager dialog box appears.
In the left pane, expand Solution, and then click Projects.
In the middle pane, select the <SegmentName>.<TechnologyFolderName>.DataModels assemblies that you added.
Note: Alternatively, you can reference the compiled DataModels assembly instead of the project. This is typically done when you only have the DataModels assembly and the DataModels project is not available.
Click OK.
