Core .ttinclude file specifies hardcoded timeout of 300 seconds at lines 1235, 1306. This will take precedence over 'Connection Timeout' option in Connection String. Please comment out or remove these lines. If there is a timeout, visual studio appears 'frozen' for 5 minutes. If a developer is doing testing and wants the timeout to something smaller, they should be able to specify that.
Thanks.
Thanks.
