Specifying Input/Output Validation via the Input/Output Tab
You can specify that you want the inputs and/or outputs of a service validated every time it executes by setting properties on the Input/Output tab of the service. Every time the service executes, the validation engine validates the input and/or output values of the service against the input and output parameters declared for the service.
To set up input and output validation via the Input/Output tab
1. In the Package Navigator view, open the service for which you want to validate input and/or output.
2. Select the Input/Output tab.
3. If you want to validate the input of the service every time the service executes, select the Validate input check box.
4. If you want to validate the output of the service every time the service executes, select the Validate output check box.
5. Select File > Save.
