Supported SQL implementations

NuGet Packages

The SQL Persister requires the NServiceBus.Persistence.Sql package, which contains:

  • APIs for manipulating EndpointConfiguration.
  • Runtime implementations of saga, timeouts, subscriptions and outbox persisters.
  • Attributes used to define compile time configuration settings.
  • [Version 4.3+] An MSBuild target that generates the required SQL installation scripts at compile time.
  • Optionally runs SQL installation scripts at endpoint startup for development purposes. See Installer Workflow.
In version 4.2 and below, The NServiceBus.Persistence.Sql.MsBuild package must also be referenced by any project that requires generating SQL installation scripts. This includes any project that contains saga classes or hosts an NServiceBus endpoint.

Other packages

  • NServiceBus.Persistence.Sql.MsBuild - In version 4.2 and below, this package must also be referenced to generate scripts. In version 4.3 and above, this package is deprecated, as the generation capability is built into the main package.
  • NServiceBus.Persistence.Sql.ScriptBuilder - This package contains the APIs that enable the generation of SQL installation scripts using code outside of a compile context. It is not intended for general usage, and in future releases, the API may evolve in ways that do not follow semantic versioning.

Script creation

SQL installation scripts are created as a compile-time output alongside a project's binary outputs. Additionally, these scripts can be promoted to a directory under source control so that differences can be easily tracked and analyzed. To learn more, see Controlling Script Generation.
