Question Connection String error - maybe LINQ related

Greetings all

I hope I am posting correctly. I am not sure whether I should be here or in a specific book. As Imar has suggested that, if I feel that I am at all off a specific book related question, it is better to choose here; that is what I have done.

I have successfully displayed data using the basic SQL access but I am now trying to move on to the LINQ stuff.

I believe I followed all the instructions carefully, particularly page 481 onwards of Beginning ASP.NET 4 by Imar BUT I now get the following Output error message -

Could not parse the configuration file. The error message is: 'The 'provider connectionstring' keyword is not supported.'. Try editing the file manually and then saving it.
I am not too sure where I should be editing, web.config? I am also not too sure what bit is wrong, the message 'seems' to be quite vague, to me.

I have pasted my web.config below, just in case anybody can immediately see an error.

Any ideas, please.

With thanks in anticipation

Hi there,

It should be:

provider connection string
with a space instead of

provider connectionstring
Hope this helps,
