Go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools (usual path) via the command prompt
paste svcutil.exe /t:metadata <Inbound port WSDL URI> and enter. This will save the schema of the service at location which will be specified in the command window.
The output will be as follows.
Now you can open the below xsd file as below snapshot.
Let me know if this helps 🙂
