Recently I needed the Microsoft Service Configuration Editor in Visual Studio but could not find it while right clicking the app.config file. Below a workaround for the issue.
If you edit the configuration file of a WCF Web Service project in Visual Studio by right-clicking it in Solution Explorer, notice that the Edit WCF Config context menu item is missing. To workaround this issue, click the Tools menu, and choose WCF Service Config Editor. After that, you can right-click a configuration file and use the Edit WCF Config context menu item.
