error using oracle.manageddataaccess.client in a WPF application

ciceroan

hi,

we are having issues with a WPF-MVVM application using Oracle.ManagedDataAccess.Client. We have installed oracle.manageddataaccess.dll, release 12.1.0.1.0 on a developer computer with Windows 7 64 bit OS, Microsoft Visual Studio 2013 and Microsoft .NET Framework 4. Installation seems to be ok, and oracle.manageddataaccess.dll results to be registered in c:\windows\microsoft .net\assembly\GAC_MSIL. But when we try to compile the app, the following errors occurs

Error 175: The ADO.NET provider with invariant name 'Oracle.ManagedDataAccess.Client' is either not registered in the machine or application config file, or could not be loaded

errors are caused by the Entity Data Model files (there is an error for each .edmx file).

notice that the app works on another computer having the same configuration, so I guess the problem is due to some wrong setting on the computer

any idea?

hi,

at last we fixed the issue! simply, we uninstalled and reinstalled Visual Studio and Oracle.manageddataaccess in this order. Now it works. thank you

Error 175 usually indicates a problem with the <DbProviderFactories> section of your machine.config or app/web.config file. Compare the settings and XML between the computer that's working and not working.
