Frequently asked question

When do COM references have to be released?

Last Published: April 25, 2020


In .NET ArcGIS Engine applications, to ensure a COM object is released when it goes out of scope, use the ComReleaser class for all singletons. The ComReleaser class can be found in the ESRI.ArcGIS.ADF.dll assembly.
Explicitly releasing COM references is not necessary for ArcGIS Desktop applications.
