Delphi 8 is a .NET-only release that compiles Delphi Object Pascal code into .NET CIL. The IDE has been rewritten for this purpose and has changed to a docked interface similar to Microsoft's Visual Studio.NET.

Daniele is working on the DelphiMVCFramework Handbook! Stay tuned!
How to correctly get the source
It is not needed to download the git repository. Just download the latest version as zip file and you are ok.If you want to partecipate to the testing phase (which usually contains brand new features) you can get the latest Release Candidate version.Take in mind that, even if RCs are usually very stable, they are still not ready for production utilization.

Roadmap
DelphiMVCFramework roadmap is always updated as-soon-as the features planned are implemented. Check the roadmap here.
Trainings, consultancy or custom development service
As you know, good support on open source software is a must for professional users.If you need trainings, consultancy or custom developments on DelphiMVCFramework, send an email to dmvcframework at bittime dot it. Alternatively you can send a request using the contacts forms on bittimeprofessionals website. bit Time Professionals is the company behind DelphiMVCFramework, al the main developers works there.
Using mapping framework in Delphi Starter Edition
A lot of users ask about it, now is possible to use the mapper framework also in Delphi Started Edition. To enable the 'StarterEditionMode' open sourcesdmvcframework.inc
and remove the dot (.) after the curly brace in the following line
{.$DEFINE STARTEREDITION}
become
{$DEFINE STARTEREDITION}

Samples and documentation
DMVCFramework is provided with a lot of examples focused on specific functionality.All samples are in Samples folder.Check the DMVCFramework Developer Guide (work in progress).
Below the is a basic sample of a DMVCFramework server wich can be deployed as standa-alone application, as an Apache module or as ISAPI dll. This flexibility is provided by the Delphi WebBroker framework (built-in in Delphi since Delphi 4).The project containes an IDE Expert which make creating DMVCFramework project a breeze. However not all the Delphi version are supported, so here's the manual version (which is not complicated at all).
To create this server, you have to create a new Delphi Projects -> WebBroker -> WebServerApplication
. Then add the following changes to the webmodule.
Remember that the files inside the redist folder must be in the executable path or in the system path. If starting the server whithin the IDE doesn't works, try to run the executable outside the IDE and check the dependencies.That's it! You have just created your first DelphiMVCFramework. Now you have to add a controller to respond to the http request.
Sample Controller
Below a basic sample of a DMVCFramework controller with 2 action
Now you have a performant RESTful server wich respond to the following URLs:
- GET /users/($id) (eg. /users/1, /users/45 etc)
- PUT /users/($id) (eg. /users/1, /users/45 etc with the JSON data in the request body)
- POST /users (the JSON data must be in the request body)
Quick Creation of DelphiMVCFramework Server
If you dont plan to deploy your DMVCFramework server behind a webserver (apache or IIS) you can also pack more than one listener application server into one single executable. In this case, the process is a bit different and involves the creation of a listener context. However, create a new server is a simple task:
If you want to add a layer of security (in its WebModule you should add the security middleware):
In stand alone mode you can work with a context that supports multiple listeners servers:
