1646007 - Deployed Windows application stops responding when a report is launched


  • Application compiled with framework 4.0 works as expected in the development environment
  • Application passes ADO .NET Datasets to the reports and thus the crdbadoplus.dll database driver
  • Application uses an app.config file to configure mixed assembly mode as crdbadoplus.dll requires framework 2.0
  • When the application is deployed and run, it terminates with no error
  • Event logs report the following;

ApplicationTest1 has encountered an error and needs to close



  • The app.config file which is saved into the root of the application on the development system that was being deployed
  • When an application is compiled a file called ApplicationTest.exe.config is created and saved into the Release folder


  • Deploy the ApplicationTest.exe.config, not the app.config file
