Multiple database connections using EntityDiagrams

[Richard M]

I am trying to create 2 separate EntityDiagrams for 2 separate databases.  My linq query worked fine in a test application, but when I tried that same query in another application, it would not work, and I would get the following error:

System.ArgumentException: Format of the initialization string does not conform to specification starting at index 57.
   at Telerik.OpenAccess.RT.Adonet2Generic.Impl.DBDriver.connect(ConnectionString connectionString, IDictionary driverProps)
   at OpenAccessRuntime.Relational.conn.RelationalConnectionPool.createRealCon()
   at OpenAccessRuntime.Relational.conn.RelationalConnectionPool.init()
   at OpenAccessRuntime.Relational.RelationalStorageManagerFactory.connect()
   at OpenAccessRuntime.Relational.RelationalStorageManagerFactory..ctor(StorageManagerFactoryBuilder b)
   at OpenAccessRuntime.storagemanager.StorageManagerFactoryBuilder.createSmfForURL()

The only difference that I can see is that the 2nd application has multiple EntityDiagrams.

Hi Richard M,

This exception usually means that the connection string needed for the domain model is not present in the configuration file of the currently executing assembly. Copying the appropriate connection string to your second application should fix the problem.
Nevertheless, we should really improve the exception message to be more descriptive. I will add this entry to our product backlog system.

All the best,
Alexander

Thank you, I will try that.
