Entity Framework

Sentry provides an integration with EntityFramework through the of the Sentry.EntityFramework NuGet package.

Looking for EntityFramework Core? That integration is achieved through the Sentry.Extensions.Logging package.


Install-Package Sentry.EntityFramework -Version 1.0.0

This package extends Sentry main SDK. That means that besides the EF features, through this package you'll also get access to all API and features available in the main Sentry SDK.


  • Queries as breadcrumbs
  • Validation errors

All queries executed are added as breadcrumbs and are sent with any event which happens on the same scope. Besides that, validation errors are also included as Extra.


There are 2 steps to adding Entity Framework 6 support to your project:

  • Call SentryDatabaseLogging.UseBreadcrumbs() to either your application's startup method, or into a static constructor inside your Entity Framework object. Make sure you only call this method once! This will add the interceptor to Entity Framework to log database queries.
  • When initializing the SDK, call the extension method AddEntityFramework() on SentryOptions. This will register all error processors to extract extra data, such as validation errors, from the exceptions thrown by Entity Framework.

Example configuration

For example, configuring an ASP.NET app with global.asax:

public class MvcApplication : System.Web.HttpApplication
    private IDisposable _sentrySdk;

    protected void Application_Start()
        // We add the query logging here so multiple DbContexts in the same project are supported
        _sentrySdk = SentrySdk.Init(o =>
            // We store the DSN inside Web.config
            o.Dsn = new Dsn(ConfigurationManager.AppSettings["SentryDsn"]);
            // Add the EntityFramework integration

    // Global error catcher
    protected void Application_Error()
        var exception = Server.GetLastError();

    public override void Dispose()
