I got this error from my window service application

the type initializer for System.Data.SqlClient.SqlConnection threw an exception.

The following is the code:

Sqlconnection objconn = new SqlConnection("Data Source=Server1;Initial Catalog=Personel;Integrated Security=True");

I am not using the app.config. I tried a different way but still failed.

Regards

I realize you stated that you're not using the app.config, but try this:

If your app.config has a CustomConfiguration section, comment it out.

Thanks for the input. I deleted the app.config becuase it was corrupt. When I tried to view the properties of the config it gave me an error message.
I added a new one, add my values, deploy to production server, then it works.

Thanks for input.

There are lots od threads on internet discussing he same. Have a look at these two for now:
Changes in the SqlConnection class (.NET 2.0) [^]
Similar issue discussed at length[^]

It might be because of some unwanted tag in your app.config or your machine.config might have got corrupted. Looking deeper into the inner exception would surely help.
