They went on to deliver 30+ projects on time and on budget!

It’s been a while since the last post, but there are plans to revamp TrueView – a brand new WPF interface and usability improvements are top of the list

In the meantime, we wish all of our customers and colleagues a very Merry Christmas and a prosperous New Year!

POCO support

TrueView now supports POCO classes, that don’t need to be inherited or marked up with attributes. Now you can re-use your POCO assemblies in other applications, and remove the dependency on the TrueView framework.

To make your POCO classes viewable in the UI, add the following property:

    public Guid ID { get; set; }

To make your classes persistable, add a Version property:

    public long Version { get; set; }

Domain Class enhancements

• Domain Classes no longer need to be marked with attributes
• Optional Configuration classes can decouple Domain Objects from the TrueView framework
• Better support for structs

Infrastructure Class enhancements

• Infrastructure classes are now decoupled from Domain Classes.
• IPersistenceInfrastructureService is now exposed, allowing custom Services to be injected at run-time.  TrueView provides FilePersistenceService and NhibernatePersistenceServices out of the box.
• IExportInfrastructureService replaces the old PrintProvider, and allows you to export data for any Domain Object
• IPresenterInfrastructureService replaces the old IUiPresenter.  You can control the formatting, and well as providing custom ‘adornments’ to display

UI enhancements

• Error indicators are now shown next to the property that caused them
• Custom adornments can be rendered next to an item in the Explorer view
• Better use of screen estate using multiple columns
• Improved drag/drop tips now show why certain operations cannot be performed
• Inline Object and List properties allow users to see more detail without having to drill-down manually.
• Hyperlinks make it easier to navigate to associated Objects and Lists
• Additional Enum display options include Slider and Radio-Options.
• Enum items can be filtered using IQuerySpecification<T>
• A new Export function replaces the old Print option

Check out the included sample code to learn about the new features.

P.S. There’s a new DomainTypes library available as well.

• Better support for true DDD concepts
• Allow code models to be reused without TrueView
• Configuration without using .NET attributes
• Open architecture, to let consumers develop custom ‘persistence providers’
• More UI interception points, to allow greater customisation
• Auto-databinding features, for WPF and possibly Silverlight
• N-Tier support (finally)

And we’re considering making TrueView FREE for non-commercial use.

We’re going to need beta-testers for the new version, so if you’re interested please email us.

In the meantime, have a very Happy Christmas!

Evolving Software releases an update of “TrueView for .NET”, a framework for rapidly designing and creating business applications for Microsoft .NET.

TrueView helps .NET Developers and Business Experts share business knowledge, design interactive prototypes, and create flexible applications. Software teams use Domain Driven Design (an established technique for designing complex applications) to stay focused on essential business concepts.

“Absorbing business concepts can be pretty tough for development teams, especially when timescales are tight. Using TrueView, Developers can sit down with Business Experts, and use interactive prototypes to discuss the problem space. The feedback cycle reduces from days to hours.” explains Vijay Patel, founder of Evolving Software.

TrueView supports Agile development, Domain Driven Design, and the Naked Objects pattern. Combining these strategies allows developers to cut development times without compromising software quality.

Evolving Software is also offering personal licences to developers learning Domain Driven Design at discounted rates. Visit http://www.evolving-software.co.uk to learn more.

Update: Listen to part 2 here.

Now might be a good time to start afresh, and replace those applications using Domain Driven Design and TrueView.
