Opening SqlConnection inside TransactionScope error - azure

Question

We have been trying to use a SqlConnection within a TransactionScope. When we build the site and try this database call we run into an error:
A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
The error involved occurs on the line cnn.Open().
using (var scope = new TransactionScope())
using (var cnn = new SqlConnection(connectionString))
{
cnn.Open();
int result = cnn.QuerySingle<int>("SELECT 1");
Console.WriteLine(result);
}
We created a console application to figure out what was wrong and discovered that by changing our connection string keyword 'Pooling' from 'false' to 'true' allows this to run in the console application and successfully return our result.
We made the same change to our site connection string, the same error as before returns.
Is there any reason this code is not working?

Answer 1

I was under the assumption that the web.config was law, as viewing the file through the Kudu service showed my expected connection string, but apparently this isn't the case in Azure.
I discovered that Azure Publish Profile is overriding our web.config connection string, this override still contained 'Pooling=false'.
Removing this now allows our code to run as intended.

"When this code runs on a developer’s local machine, the value returned will be the one from the web.config file. However when this code runs in Windows Azure Web Sites, the value returned will instead be overridden with the value entered in the portal"
