Abstract: Methods for resolving anomalies for network applications using code injection are performed by network services systems. Notifications for electronic communications incoming to executing applications are received and monitored on the network services system. The notifications are analyzed to identify anomalies in the electronic communications for executing applications. Application contexts associated with executing applications are determined, and code solutions are selected from a set of code solutions to correspondingly apply against the anomalies. Code solutions include code blocks, scripts, or code assemblies to resolve specific anomalies for executing applications. Code solutions are selected based on the application contexts and the one or more anomalies. Selected code solutions are injected into the first executing application to resolve or mitigate the anomalies.
