EF Code First - Timeout expired. The timeout period elapsed prior to completion

c# ef-migrations entity-framework sql-server

Question

Apology for this strangely worded question. I don't know what the actual problem is but hopefully someone can give me some insights.

I am getting the following error when trying to run migrations:

Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding. ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out

It is interesting to note that on my laptop this is not happening but on my VM (azure - large) this is happening with 100% failure rate.

I am using Ef 6.0.0 -rc1. Please note, updating EF is not an option. If updating to EF 6.0.0 or 6.0.1 I will get the following error with 100% failure rate:

Errors during Code First add-migration

I have also timed the error. It takes about 1.5 min to trigger the error. When running with -Verbose flag it was trying to create 200 tables with indexes. Copying the sql query and excuting it in SSMS takes 5 secs.

A few things that I have tired but didn't work:

1) Setting ObjectContext.CommandTimeout = 36000 // 10 hours! as indicated here:

https://stackoverflow.com/a/6234593/305469

2) Setting timeout in connection string in "web.config":

connectionString="Data Source=localhost;Initial Catalog=myDB;Integrated Security=SSPI;Connection Timeout=36000"

3) Setting "machine.config" transaction maxTimeout:

<system.transactions> <machineSettings maxTimeout="00:00:00" /> </system.transactions>

4) Setting "remote query timeout" on sql server

USE MyDB;
GO
EXEC sp_configure 'remote query timeout', 0 ;
GO
RECONFIGURE ;
GO

So what is happening? How come CommandTimeout is not being respected? Any suggestions?

In the constructor of Configuration.cs class (in migration Folder) add the property CommandTimeout = Int32.MaxValue;
