Enterprise Library / Unity vNext

Greetings!

This is a public forum for you to suggest/vote on the ideas for future capabilities/updates to Enterprise Library and Unity.

Please note the list may not always represent the actual prioritized backlog of the development team.

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Enhance Performance of the IsRegistered Check on Type Registrations for Unity

    This would allow for more performant resolution of multiple dependency resolvers. See using Unity with SignalR for an example, or this discussion on Unity's Codeplex site - http://unity.codeplex.com/discussions/392550

    • A Collection of Common Aspects to be Used With Unity Built on Other Application Blocks

      Aspects such as a Logging, Authentication, Authorization, Performance Monitoring, Caching, etc... that do not require attributes but can be configured by interception. Though perhaps attributes can *also* be used to add them.

      A common set of these would help remove a number of cross-cutting concerns from all manner of developer's applications.

      • Lightweight Scheduler / Job coordinator

        A higher level abstraction like you created for the CQRS journey to process commands would be really useful.

        Something with a simple API that:

        * uses queues to activate jobs (service bus, azure, inmemory) or time-based (schedule)
        * that can run in process or in a separate worker
        * leverage TPL to maximize throughput
        * that can scale out to multiple nodes
        * graceful exception handling
        * load/stress tested

        • TPL Application Block or TPL Helpers

          Not sure if this is app block or a helper (like the original and highly popular single file SqlHelper released by p&p circa 2006). Async is hard to grasp (easier with NET 4.5, but still). A higher level simple library that help us implementing common patterns and best practices on top of TPL (sequential/parallel execution, fire and forget, wrap sync libraries, coordination patterns, server side good practices, etc.).

          See here for some of the needs:

          • Extend Automatic Factories to automatically use Parameter Overrides

            The current system of Automatic factories in Unity defers resolution when a class's constructor has a dependency of Func<IMyService>. This could be extended to automatically use parameter overrides when it sees a dependency of Func<SomeType,IMyService> and the concrete class implementing IMyService needs a parameter of type SomeType. This would only kick in if an InjectionFactory of the required type wasn't registered.

            • Hierarchical Loggers like log4net

              we have component_xx.exe with his dependency component_xx.data.dll and in log4net and log4j
              you have the ability to include specify for namespace ex. component_xx_data.model to log only information’s and for component_xx_data.model.error to log only errors

              • Allow custom default LifetimeManagers

                One of the things I like most about Unity, is that Unity can build object trees, even if not all types used in the object tree are explicitly registered.
                However, if I want to use a custom default LifetimeManager, I do have to register all types with the custom LifetimeManager, because Unity does not support a custom default LifetimeManager.
                So, the request is simple: make the default LifetimeManager type configurable.

                E.g.:
                var container = new UnityContainer();
                container.ChangeDefaultLifetimeManagerTo<ContainerControlledLifetimeManager>();

                • Support a Rolling Database Trace Listener

                  The Database Trace Listener and the supplied stored procedure are not really helpful over time. The database is growing indefinetly. It would be cool to have a similar mechanism as the rolling file listener.
                  The database can specify how large it can grow maximum and old entries are deleted automatically.

                  • Entlib Logging for HTML 5 Applications

                    In ASP.MVC 4 there's a Template that generates Single Page Applications in Browser. Much more code is running in the browser runtime and the need for Tracing and ErrorLogging is higher in these scenarios. Are there any plans to support HTML 5 Applications that are built with the Single Page Pattern?

                    I would like wish to see a similar support that has been built for Silverlight. Especially a centralized LoggingServices that supports ASP.NET, MVC and WCF and accepts JSON LogEntries. A client side javascript library and configuration would help to generate these messages via ajax and send them asynchronously. I…

                    • Add support for all the Autofac Relationship types

                      In this article: http://nblumhardt.com/2010/01/the-relationship-zoo/, Nicholas Blumhardt talks about relationship types supported by Autofac. Othe IoC containers have supported some if not all of these over the years, Unity needs to catch up.

                      The Lazy<T> and the Owned<T> relationship type are the most interesting from a what's currently missing point of view.

                              3) Building configuration from several files at the same time.

                              Make XML config file syntax more concise and Source-Control friendly.

                              • wcf service factory

                                Exposing a unity-managed object with wcf through a svc file is a common scenario. It would be great if Unity could provide a wcf factory out of the box, so it would be possible to use it directly instead of writing our own (many examples on the web).

                                  it would be great to register nested objects instead of using dendencyName. This way the xml, will reflect the object tree visually.

                                      • Use claims for authorization checks

                                        As a developer I want to be able to leverage a ClaimsPrincipal for the authorization checks using the Security Application Block. The claims that are recognized as identity or roles should tie into the authorization providers (AuthorizationRuleProvider and AzManAuthorizationProvider). Currently the AzMan provider seems dependent on Windows identities.
