You are creating a Web Services type service interface that uses CICS commareas. 
	 
 
	  
		- From the Solution Explorer, right-click the 
		  CICSCommareaWS project; then click 
		  Add > 
		  New Item. 
		
- Expand 
		  Native and click 
		  Mainframe Subsystem. 
		
- In the center pane, click 
		  Service Interface. 
		
- In the 
		  Name field, type 
		  CICSCommareaWS; then click 
		  Add. 
		
- Select 
		  Web Service as your type of interface and 
		  CICS Commarea as your type of source. All other fields retain their default values.
		
- Click 
		  OK.
		
At this point, Visual Studio adds the 
		CICSCommareaWS service interface to the Solution Explorer and invokes the Interface Mapper. You are ready to define the details of the service interface.
