We’ve released LLBLGen Pro  v5.0 CTP 1! It’s a Community Technical Preview (CTP) of the upcoming v5.0 which is in development since fall 2014. The CTP is open for all v4.x customers (it’s in the customer area, in the v4.2, betas section) and comes with a time-limited license which expires on June 1st, 2015. As this isn’t a full beta, (much) more features are added before beta hits.

Below I’d like to show some of the new features in action. Click the screenshots for a bigger version.

New, skinnable UI

A new UI was long overdue. The current (v4.2) version still uses VS.NET 2008 like toolbars/controls and it looks just… dated. So, we ported the complete UI to DevExpress controls (still winforms though) as some of our controls were already based on those. The screenshots below show the default VS.NET 2013 white theme.

New Relational Model Data Sync System

In short: the Sync system. Sync replaces both database first related actions like refresh catalog and model first related actions like auto-map and adjust relational model data. It allows a sync source to be set for a schema which controls the source from where table related relational model data is obtained from: the database or the entity model. Stored procedures/views/tvfs are always obtained from the database. Everything is managed from a single tab, the Sync Relational Model Data tab, which is opened by clicking the sync button on the toolbar or menu item in the project menu.

LLBLGenProv5_SyncScreenShot


A big benefit from the new system is that it will function even when the project contains errors: it's no longer necessary to correct project elements before a refresh. It also doesn't adjust relational model data on database synced schemas, so it's no longer required to export DDL SQL before code generation because the validation adjusted some fields based on a change.

Revamped Home tab

The Home tab now shows active tiles the user can click to navigate through one of the scenarios (database first / model first and new / existing project). Which tiles are shown depends on what the user did last and the state of the designer.

LLBLGenProv5_HomeTab1ScreenShot

It's an easy way to get started with the designer and replaces the webpage based home tab which was static.

It acts like a wizard in disguise: you can do the basic tasks right from the home tab, by clicking tiles. Here I’ve opened a Database first project and the state of the designer now shows different tiles with different actions.

Search in Project Explorer / Catalog Explorer

Directly available in the Project Explorer and Catalog Explorer are the search boxes: type in any string and the nodes matching the string are kept, all other nodes are filtered out. This allows finding elements with ease. Removing the search replaces the tree as it was before the search. In the below screenshot I’ve searched for ‘Sales’ in both the project explorer and the catalog explorer. It shows all nodes matching the string specified, including parent nodes (to give context) and hiding other nodes. The more advanced, LINQ query based search is still available in the designer, but this dedicated search on the two explorer panes is easier to use and requires no extra forms to navigate.

Real Time Validation

The designer got a real time system to schedule and run tasks at will through several dedicated dispatch queues. This greatly helps offload work from the UI thread while not having to mess with multi-threading as it utilizes the .NET 4.5 Task Parallel Library. Configuring work is as easy as defining an event, a handler and which dispatch queue to run the handler call and the system takes care of the rest, including overflow protection (so only a limited number of calls are allowed per interval).

The real-time validation in action:

So these are the highlights of this CTP (there are many tiny improvements under the hood too). We’ve much more in store for v5.0, so stay tuned Smile

I caved. For years I’ve denied requests from customers to publish the LLBLGen Pro runtime framework assemblies on nuget, for the reason that if we had to introduce an emergency fix in the runtimes which also required template changes, people with dependencies on the nuget packages would have a problem. While this might be true in theory, in practice it’s so uncommon that this will happen, it more and more turned into an excuse.

Add to that that customers started publishing the runtimes themselves on nuget, it was time to bite the bullet and publish the runtimes ourselves, officially. So we did. At the same time we published the interceptor assemblies of ORM Profiler on nuget.

The URLs

For LLBLGen Pro:

https://www.nuget.org/packages/SD.LLBLGen.Pro.ORMSupportClasses/
https://www.nuget.org/packages/SD.LLBLGen.Pro.ORMSupportClasses.Web/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.Access/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.DB2/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.Firebird/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.MySql/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.OracleMS/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.OracleODPNET/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.PostgreSql/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.SqlServer/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.SybaseAsa/
https://www.nuget.org/packages/SD.LLBLGen.Pro.DQE.SybaseAse/

For ORM Profiler:

https://www.nuget.org/packages/SD.Tools.OrmProfiler.Interceptor.EFv6/
https://www.nuget.org/packages/SD.Tools.OrmProfiler.Interceptor.NET45/
https://www.nuget.org/packages/SD.Tools.OrmProfiler.Interceptor/

Who are these assemblies for?

The assemblies are for customers who want to stay up to date with the latest runtimes. Every time we publish a new build, the runtimes and interceptor dlls are automatically updated with the latest build. We never introduce breaking changes in released assemblies, so they’re safe to use in code and update to the latest version.

How are they versioned?

The LLBLGen Pro Runtime Framework assemblies are versioned as: 4.2.yyyymmdd, where yyymmdd is the build-date. The ORM Profiler interceptors are versioned as: 1.5.yyyymmdd.

What’s in the packages?

The DQE packages come with a single DLL, the DQE dll, and have a dependency on the ORMSupportClasses package. The ORMSupportClasses package contains both the .NET 3.5 build and the .NET 4.5 build with async support: if your project targets .NET 4.5 you automatically will reference the .NET 4.5 build with async support.

The Interceptor packages contain the interceptor dll and support dlls which don’t need their separate package. The Entity Framework interceptor has a dependency on Entity Framework 6.

Do the DQE packages depend on ADO.NET provider packages?

No, as all DQEs work with the DbProviderFactory system and don’t need the using project to reference an ADO.NET provider reference. The ADO.NET provider has to be present on the system, but as the provider assembly doesn’t need to be referenced by the VS.NET project the DQE package doesn’t need a direct dependency on the related ADO.NET provider package as that would mean the ADO.NET provider dll would be directly referenced after the DQE package has been installed.

Hope this helps the customers out who have asked us for so long for this feature Smile
