Connection error message: keyword not supported: 'initial catalog'

The error occurs in the Global.asax file at the following line:

WebSecurity.InitializeDatabaseConnection("Action", "Member", "MemberId", "Email", autoCreateTables:= True)

Let me say that so far I've made a couple of changes to the web.config file after reading the material in 'Getting Started' and also 'Patterns in Action 4.5'. These changes are:

<connectionStrings>
<add name="Action" connectionString="Data Source=myServerName;Initial Catalog=Action;User ID=myUID;Password=myPWD"/>
</connectionStrings>

(I've changed the actual values, but you get the idea!)

I've also changed the <app settings> tag to the following:

<appSettings>
 <add key="DataProvider" value="ADO.NET" />
</appSettings>

Firstly, I'm not sure if I should also be changing the settings for the 'ActionEntities' connection string and if so what to.

Secondly, I'm fairly certain I was getting the same error message even before I made any changes. Can someone help?

TIA

Here is a post with a similar error message: http://stackoverflow.com/questions/8150737/asp-net-mvc3-connection-string-keyword-not-supported-initial-catalog

In their case it was the data provider that was the problem.  t would think that that is also the case here:
-First see if adding 'providerName="System.Data.SqlClient" to your connection string solves your problem.
-Secondly try changing the data provider from 'ADO.NET' to "Ado.Net" (although from what I remember case does not matter).

Hope this gets you going.
