Sometimes when you have created a new WCF service the “Edit WCF Configuration” context menu option is not available when you right-click on the config file (e.g. app.config). I have reproduced the problem below by creating a new class library and adding a WCF service to it. Right-clicking on the app.config file does not show the “Edit WCF Configuration” option.
To restore the missing option go to Tools > WCF Service Configuration Editor. This opens the editor but does not open the appropriate configuration file.
Close the editor immediately. Right-clicking on the configuration file will now show the previously missing “Edit WCF Configuration” option.
