Then in your connection string simply append the command timeout like so: "Data Source=SqlExpress Initial Catalog=YourDatabase Integrated Security=true Command Timeout=300" In EF Core 3 and above, you can now configure this via connection string. Extending the Command Timeout in Entity Framework Core Migrations 26 March 2018 08:50 Entity Framework ASP.NET Core Most migrations that you execute when working with Entity Framework Core are likely to be straightforward - resulting in nothing more than an adjustment to the database schema. That's my experience as of now, so let me know if you are able to fix itĮF Core 1.0 does timeout even more fast than EF Core 2.0. If it's more than that it keeps retrying and you never get to see the result. Note: EF Core will only execute the query with less than 100 seconds time.

NET Core/Entity Framework Core, you can use the CommandTimeout property. ![]() ConnectionTimeout not working Issue 10991 dotnet/efcore GitHub dotnet / efcore Public. inject this to a db entity from constructor. ConnectionTimeout 10 EF Core 7 Moving connection string out of DbContext. Net website that connects to SQL server always-on failover. Note that I also use a different connection string during migrations - the user has higher permissions than the website and the connection timeout is longer.The better option is to use CommandTimeout during your context setup like: public class DbConnect: IConnnectDb ECUserId is a varchar column and there is no index set on this table for this column. The timeout period elapsed prior to completion of the operation or the server is not responding. Migrations: timeout error in Update-Database commands DbMigrationsConfiguration.CommandTimeout Property I am using the following LINQ query using EF Core and getting the following error: Timeout expired. Internal sealed class Configuration : DbMigrationsConfigurationĪutomaticMigrationDataLossAllowed = false ĬommandTimeout = 360 // <- 6 minute timeout! My Migrations.Configuration class: using Using (var context = new M圜ontext(Config.ConnectionStringMigrations))ĭatabase.SetInitializer(new MigrateDatabaseToLatestVersion()) My DatabaseMigrationConfig Class: public class DatabaseMigrationConfig In my : protected void Application_Start() Using Entity Framework 6 (NOT CORE!), I set a longer timeout for migrations using the DbMigrationsConfiguration.CommandTimeout property. But you can set it globally in the constructor, and then remove it later if you don't need to keep it: public class ApplicationDbContext : DbContext There is no way to set the CommandTimeout on a context when using EF commands. When the tooling runs the migration, it looks first for a class that implements IDesignTimeDbContextFactory and if found, will use that for configuring the context. Make sure that your existing DbContext has a constructor that takes a DbContextOptions object as a parameter: public AdventureContext(DbContextOptions options) : base(options) Return new SampleContext(optionsBuilder.Options) Var optionsBuilder = new => opts.CommandTimeout((int)TimeSpan.FromMinutes(10).TotalSeconds)) Public SampleContext CreateDbContext(string args) Public class SampleContextFactory : IDesignTimeDbContextFactory Context pooling allows you to pay context setup costs only once at program startup, rather. This property specifies the time in seconds that the system should wait for the command to execute before throwing an exception. For these cases, EF Core can pool your context instances: when you dispose your context, EF Core resets its state and stores it in an internal pool when a new instance is next requested, that pooled instance is returned instead of setting up a new one. The error message you are getting is for a Command timeout, not a connection timeout.Īs mentioned by Pace in comments, since EF Core 2.0 you are able to use IDesignTimeDbContextFactory to change the behaviour of your context when it is being created by tooling at design time such as happens with Migrations.Ĭreate a separate class in your project that implements the IDesignTimeDbContextFactory interface and use the DbContextoptionsBuilder to configure the behaviour you want - in this case, setting the command timeout value to 600 seconds: using Microsoft.EntityFrameworkCore To set the command timeout in ASP.NET Core/Entity Framework Core, you can use the CommandTimeout property. ![]()
