Disabling EF table creation

In my application I am using EF6 to map into an existing database where I do not have control of the schema.

When the first Db call is made I get an exception where create table is not allowed, which its not and database initialisation should be disabled.

System.Data.SqlClient.SqlException (0x80131904): CREATE TABLE permission denied in database 'ADatabase'.

I have followed various methods of disabling initialisation using both code and config but none seem to be working.

I have tried implementing DbConfiguration for auto discovery, explicitly calling it in my Application_Start as well as Database.SetInitializer<MyContext>(null); in the ctor for the Context.

Config was set as per Database Initializers in the MSDN article linked above (sample below)

<contexts> 
  <context type=" Blogging.BlogContext, MyAssembly" disableDatabaseInitialization="true" /> 
</contexts>

Using EF 6.1.3, .NET 4.6 and SQL Server 2008
