How do you set Command Timeout in Linqpad?

Pergunta
I have recently started using LinqPad, and bought the Autocomplete option and am really loving it. This is an excellent product!
I wanted to ask if there is a way for me to control the command timeout that used when querying a SQL Server database in LinqPAD (I am using c# statements)? I can't see where we have access to the actual connection string, and I have some large queries for reporting that are timing out. It appears that the timeout is hard-coded at 30 seconds.
Thanks in advance for any help!
Solução
I have run queries that have taken minutes and never had a command time out. That said, here's how you change it...
All of the work you perform inside a UserQuery
. The CommandTimeout
is a property of that.
this.CommandTimeout = 60;
Have a look at all the properties under this
. It gives you a nice insight into some of the things you can do.

As mentioned in @DaveShaw's answer when querying a SQL Server database in LinqPAD using a 'regular' connection, you can use:
this.CommandTimeout = 60
However, this property is not available when LinqPad connects to DB using an EF-library.
Using this.CommandTimeout
results in:
'UserQuery' does not contain a definition for 'CommandTimeout' and no extension method 'CommandTimeout' accepting a first argument of type 'UserQuery' could be found (press F4 to add a using directive or assembly reference)
Some puzzling and a this answer about EF time-outs in general led me to use this on an EF-connection:
(this as IObjectContextAdapter).ObjectContext.CommandTimeout = 60;
For Entity Framework Core connections used the following property instead.
this.Database.SetCommandTimeout(120);
