I have developed a project in WPF MVVM framework. The database part is Entity Framework and the database is Oracle 11g. When I run the .exe application in the machine where I developed it, it runs perfect but when I run it in another machine it becomes 'Not Responding'. I have tried to include the following dlls:
-oci.dll
-ociw32.dll
-orannzsbb11.dll
-oraocci11.dll
But the "Add Reference" in Visual Studio is not allowing me to add the above references. What all dlls I need to include in the solution so that it runs perfect on user's machine?
