This section provides an example of how to set up the Visual Studio development environment to debug PDS WITSMLstudio Store.
- Start PDS WITSMLstudio Desktop, or another WITSML client of your choice, and establish a connection to PDS WITSMLstudio Store.

In Visual Studio, open the PDS.WITSMLstudio.Store solution and attach to the IIS worker process by selecting Debug > Attach to Process.
In the Attach to Process dialog, search for the process w3wp.exe and attach to it.

- Open the WitsmlStore class under the Store.Core project within the PDS.WITSMLstudio submodule. Put a break point on the first line of the method WMLS_GetFromStore.

In PDS WITSMLstudio Desktop, issue a GetFromStore query as described in the User Guide for PDS WITSMLstudio Desktop.
In the PDS.WITSMLstudio.Store solution, the process will stop at the break point in the WMLS_GetFromStore method.
