“Update-Database” command fails with TimeOut exception

Question

I\'m using EF migrations and have a table with a lot of data. I need to change MaxLength of a concrete column (it hadn\'t length constraints).

ALTER TABLE MyDb A         


        

Answer 1

Found solution by myself.

Since EF5 there is a new property CommandTimeout which is available from DbMigrationsConfiguration

internal sealed class MyMigrationConfiguration : DbMigrationsConfiguration
{
    public Configuration()
    {
        CommandTimeout = 10000; // migration timeout
    }
}
