EF Execution Timeout issue when running a migration [duplicate]

I am trying to create FULL TEXT index using Entity Framework Migration by executing custom Sql.
My migration class looks like this:
public partial class DocumentContentFullTextIndex : DbMigration
{
public override void Up()
{
AlterColumn("dbo.Attachments", "ContentType", c => c.String(maxLength: 260));
Sql("CREATE FULLTEXT CATALOG FullTextIndexes AS DEFAULT;", true);
Sql(#"CREATE FULLTEXT INDEX ON [Attachments](
Content
TYPE COLUMN ContentType
Language 'ENGLISH'
)
KEY INDEX [PK_dbo.Attachments]
ON FullTextIndexes;", true);
}
public override void Down()
{
AlterColumn("dbo.Attachments", "ContentType", c => c.String(maxLength: null));
Sql("DROP FULLTEXT INDEX ON [Attachments]");
Sql("DROP FULLTEXT CATALOG FullTextIndexes");
}
}
When I run it from MSSQL management studio everything is perfect and SQL did exactly what I am expected from it.
But when running from migration project second Sql request fires exception
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I tried to copy all SQL from Verbose output exactly 'as is' and execute it directly in Management Studio and it work exactly as expected with no errors.
Any ideas how this can be fixed?
Strange thing also that if I put ContentType max length changing code
AlterColumn("dbo.Attachments", "ContentType", c => c.String(maxLength: 260));
in separate migration file everything also works fine.
UPDATE:
After shivakumar advice I tried to increase connection timeout (up to 5 minutes) in migration configuration and this increased time before I received "Timeout exception" but problem is still there.

Use Configuration.cs file to set custom time out:
internal sealed class Configuration : DbMigrationsConfiguration<ApplicationDbContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
ContextKey = "YourDbContext";
// New timeout in seconds
this.CommandTimeout = 60 * 5;
}
}

Your request processing may be taking more time than default command timeout of entity framework(30 sec).
You can increase command timeout if necessary as in thread below.

SQL Server localDB could not create file

i am trying to recreate this sample
https://learn.microsoft.com/en-us/ef/ef6/modeling/code-first/migrations/
I did everything according to the text, the program compiles fine, but then it fails creating the database
It seems like the db file
'C:\Users\WolfgangConsoleApp4.BlogContext.mdf' is missing a \ after Wolfgang.
But I do not know where to enter the path correctly.
On the laptop in my company I could rebuild and run the sample code without errors.
this is the complete exception text:
System.Data.SqlClient.SqlException
HResult=0x80131904

Maybe my VS Community Edition does not allow this?
Or maybe I have too many versions of sql server and localdb and so installed?
Greetings
Wolfgang

As #ErikEJ posted in a comment, I have to update my localdb install.
For this i used Cumulative Update 6 for SQL Server 2017.
After a restart of the pc it worked.
But code first migrations were not what i initially was searching for...
I think, I will have to post a new question...

EF Alter Table with FK error message

I run in the following error message when I try to run the Seed method.
System.Data.Entity.Infrastructure.DbUpdateException: An error occurred
while updating the entries. See the inner exception for details. --->
System.Data.Entity.Core.UpdateException: An error occurred while

The conflict occurred in database
"C:\USERS\PATH\SOURCE\REPOS\MVCMOVIE\MVCMOVIE\APP_DATA\MOVIES.MDF",
table "dbo.Genres", column 'Id'. The statement has been terminated.
This is my Configuration.cs file
namespace MvcMovie.Migrations
{

using System.Data.Entity.Migrations;
using System.Linq;
internal sealed class Configuration : DbMigrationsConfiguration<MvcMovie.Models.MovieDBContext>

}
}
}
Rating and Genres are set to be FK in the Movie table. Has anyone had this type of error before?

I have a windows service that call a Web Service, then stored the information in my t-sql database. In my pc this service works, but in another pc with the same database I have this error:

This is the code:

int result = _db.SaveChanges(); //LINE 25

return true;

The Question is unclear, but I think that error is not in the code.
The log tell that error is in save on DB, but if this application work only on your pc I think (probably) that related to different version of DB.
checks whether this is the problem

How to re-add tables based on models defined in ASP.NET MVC?

For some reason, all of my important tables have disappeared from the Database. I've deleted all of my migrations.cs files. Then, I executed a "Add-Migration Initial" and an "Update-Database", but received the following errors:
update-database -verbose

Specify the '-Verbose' flag to view the SQL statements being applied to the target database.

Cannot find the object "dbo.ProfileMeta" because it does not exist or you do not have permissions.
How do I simply automatically re-add the tables, based on the defined models first, before applying any foreign key restraints, etc...?

follow these instructions:
Delete existing migrations from Migrations_History table.
Delete existing migrations from the Migrations Folder.
Run add-migration Reset. This will create a migration in your
Migration folder that includes creating the tables (but it will not
run it so it will not error out.)
Now run update-database. It will apply the Migration and create a
snapshot row in MigrationHistory.
