Installation Changes

The following app/web.config entries are added when installing the managed ODP.NET NuGet package to your application:

1. Configuration Section Handler

A configuration section handler entry is added to the app/web.config to enable applications to add an <oracle.manageddataaccess.client> section for ODP.NET, Managed Driver-specific configuration.

Note: For a web app, if the same config section handler for "oracle.manageddataaccess.client" also exists in machine.config but the "Version" attribute values are different, an error message "There is a duplicate 'oracle.manageddataaccess.client' section defined." may be observed at runtime. To resolve the error, remove the "oracle.manageddataaccess.client" config section handler entry in the machine.config. If other applications on the machine depend on this machine.config entry, move the config section handler entry to each application's web.config file.

2. DbProviderFactories

The DbProviderFactories entry is added for applications that use DbProviderFactories and DbProviderFactory classes. Any DbProviderFactories entry for "Oracle.ManagedDataAccess.Client" in the machine.config will be ignored.

3. Dependent Assembly

The dependent assembly entry is created to ignore policy DLLs for Oracle.ManagedDataAccess.dll. It directs the app to always use the Oracle.ManagedDataAccess.dll version that is specified by the "newVersion" attribute in the "bindingRedirect" element. The "newVersion" attribute corresponds to the Oracle.ManagedDataAccess.dll version which came with the NuGet package.

4. Data Sources

The data sources entry is added to provide a template on how a data source can be configured in the app/web.config. Simply rename the sample data source to an alias of your choosing; modify the PROTOCOL, HOST, PORT, SERVICE_NAME as required; and un-comment the "dataSource" element. Once that is done, the alias can be used as the "data source" attribute in your ODP.NET connection string.
