Listing 14.2 An Information log showing the SQL command sent to the. 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. Var timeout = () // this, as expected, returns "60" We've covered how to capture EF Core's logging next, you'll see how to use this. Using var dbContext = new MyDataContext() OptionsBuilder.UseSqlServer(connection, sqlServerOptions => sqlServerOptions.CommandTimeout(60)) īut then when I execute the code in my web API: Protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) Connector/NET supports timeouts that are aligned with how. ef core connection timeout The CommandTimeout parameter is measured in seconds and controls for how long to wait for a command to finish before throwing an. My context object looks something like this: public class MyDataContext : DbContext To change the default command timeout, use the connection string option Default Command Timeout. 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. 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.I am finding that neither the DatabaseFacade.SetCommandTimeout method nor the SqlServerDbContextOptionsBuilder.CommandTimeout method are having any effect on my code and instead a long running SQL command just continues indefinitely. 1 I am using the following LINQ query using EF Core and getting the following error: Timeout expired. Migrations: timeout error in Update-Database commands DbMigrationsConfiguration.CommandTimeout Property Internal sealed class Configuration : DbMigrationsConfigurationĪutomaticMigrationDataLossAllowed = false ĬommandTimeout = 360 // <- 6 minute timeout!

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 of twenty-three officers under the command of Chief Ryan McNamee. 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) is limiting the time of executing the SQL query (imagine some super complex SQL command with many joins, cartesian products, group by, subqueries etc. Var optionsBuilder = new => opts.CommandTimeout((int)TimeSpan.FromMinutes(10).TotalSeconds)) Command timeout is just for the ExecuteXYZ part of the database command, which for queries is ExecuteReader, i.e. Public SampleContext CreateDbContext(string args) Public class SampleContextFactory : IDesignTimeDbContextFactory ![]() in aircraft etizolam paypal ef core connection timeout kirsten rees bristol. 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 Press Windows + R keys to bring up the Run command or right-click on the. ![]()
