In the code line below, I'm getting the errors below. I copied this from a web.config to the web.config I'm using:

<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>
<dataConfiguration defaultDatabase="ISDBConnectionString"/>
<connectionStrings>
<add name="ISDBConnectionString" connectionString="servername;Initial Catalog=databasename;Integrated Security=true;" providerName="System.Data.SqlClient"/>
</connectionStrings>

code:
Database SqlDb = DatabaseFactory.CreateDatabase(ConfigManager.ConnectionStrings["ISDBConnectionString"].ToString());

Errors:
Microsoft.Practices.ServiceLocation.ActivationException was unhandled by user code

I know there's a lot of detail in there, but not a whole lot of clarity.
What are you you trying to do?

It looks like you're working through a MS sample project.
Did you remove the database connection string details or is it really Database, key "Data Source=servername;Initial Catalog=databasename;Integrated Security=true;"

You have to update the web.config file to point to YOUR database server, that has AdventureWorks on it.

You've got questions and source code. We want both!
There's a whole lot of Irish in that one.

Thanks Qik3Coder. The problem was that the bin directory had the strong typed DLLs and I was referencing the dlls without the key. I added the dlls without the key and the error was resolved. Here is more detail:
