    Im using Enterprise library 5.0
    I have a scenario, where I have to access two different databases in my application.

    Basically this application is a webservice,delployed on my local for testing purpose.
    I'm trying to access this web method from diffent windows application, default connection works fine but the other database throw's exception.

    Problem is only my defaultDatabase is works fine, if I change defaultDatabase="MYCON1" with "MYCON2" it works fine, if I try to access the other database which is not default, throws exception.

    <dataConfiguration defaultDatabase="MYCON1" />
    <add name="MYCON1" connectionString="Data Source=server1;Initial Catalog=dbName1;User Id=Username1;Password=password1;"

    " />
    <add name="MYCON2" connectionString="Data Source=Server2;Initial Catalog=dbName2;User Id=Username2;Password=password2;"
    providerName="System.Data.SqlClient" />

    Database myDB=EnterpriseLibraryContainer.Current.GetInstance<Database>(); --> works fine for the default database (MYCON1)

    Database myDB=EnterpriseLibraryContainer.Current.GetInstance<Database>("MYCON2"); --> Error message, see below

    Activation error occured while trying to get instance of type Database, key "MYCON2"

    I don't see any issues with the syntax. I have used similer code & it works fine. Does your second database exists?
