"Update-Database" command fails with TimeOut exception

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 ALTER COLUMN [MyColumn] [nvarchar](2) NULL

And this command fails with TimeOut exception.
Tried to setup CommandTimeout i nDbContext constructor without any luck.

Is there any way to disable or setup timeout for Package Manager Console EF commands?

Found solution by myself.

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

internal sealed class MyMigrationConfiguration : DbMigrationsConfiguration<MyDbContext>
    public Configuration()
        CommandTimeout = 10000; // migration timeout
