Bogue BUG-000102447


The EnvironmentManager singleton object in the ServerLogger.GetServerEnvironment method is not instantiated following the documentation.

Informations supplémentaires

The issue is not reproducible using our own programs and no code has been submitted that does reproduce the issue. Additional steps have been requested to reproduce the issue, but no further steps are available. If additional steps to reproduce the problem can be provided then the issue can be re-evaluated.

Autre solution

Several ArcGIS GIS Server 10.6.1 users experienced "System.InvalidCastException: Unable to cast object of type 'System.__ComObject' to type 'ESRI.ArcGIS.esriSystem.EnvironmentManagerClass'." exception thrown at 
IEnvironmentManager environmentManager = new EnvironmentManager() as IEnvironmentManager;

To fix the above exception, instantiate EnvironmentManager as singleton as the code below:
Type t = Type.GetTypeFromProgID("esriSystem.EnvironmentManager");
System.Object obj = Activator.CreateInstance(t);
IEnvironmentManager pEnvMgr = obj as IEnvironmentManager;
