Fortran for .NET allows you to create applications for the Microsoft
.NET Framework. Lahey and Fujitsu have combined advanced compiler
technology with support for Forms designers and Web Services to enable
Fortran organizations to develop .NET applications with Fortran as
easily as with other Microsoft .NET languages. Fortran for .NET
consists of a Fortran compiler and associated tools designed to
help you create applications that run in the .NET Framework.
The Fortran for .NET language system is included in LF Fortran v7.1
Enterprise and Academic editions.
Fortran for .NET compiler
Th Fortran for .NET compiler targets Microsoft's .NET Framework. The compiler
does not directly generate processor dependent object code; rather, it
generates Microsoft Intermediate Language (MSIL) code assemblies and code
modules. The code in an assembly can be executed on any computer that
supports an execution engine called the Common Language Runtime (CLR), such
as the .NET Framework.
The CLR does much more than provide the ability to operate on different
operating systems, it also provides the basis for interoperability between
different .NET languages, interlanguage debugging, versioning, and
application deployment, among other things.
Applications that are targeted for the CLR are called managed applications,
or managed code. Managed applications are required to be type safe and to
present standardized interfaces, so that interoperability and security
requirements can be met. Because some older Fortran features (such as
COMMON and EQUIVALENCE) can violate the CLRs rules for type safety and
interfaces, certain restrictions had to be placed on .NET applications
that do not allow 100% compatibility with Fortran standards. For details
on restrictions, see Restrictions on Fortran for .NET Code.

Visual Studio .NET integration
Visual Studio .NET 2003 is the industry standard in development
environments. Fortran for .NET Visual Studio integration includes
project management facilities, project/code
templates, on-line integrated help, Fortran-smart editing, and
mixed-language debugging.
Project Management
To efficiently manage the items that are required by your development
effort, such as references, data connections, folders, and files,
Visual Studio .NET provides two containers: solutions and projects.
An interface for viewing and managing these containers and their
associated items, Solution Explorer, is provided as part of the
integrated development environment (IDE).
Project/Code Templates
Project/code templates syntactically correct compilable source code
shells and associated project setting that help you create applications
or services. Fortran for .NET provides the following Visual Studio
project types:
- The Empty Project template provides a solution and project
without any source files or references. You can add items to this
project by using the "Project/Add New Item" menu selection.
- The Class Library template consists of a library project
and a skeletal Fortran class library containing a single static
method. When compiled, this project type creates a .NET DLL file,
which may be supplied as a reference to other .NET applications.
- The Console Application consists of a console project,
and a skeletal main program. When compiled, this project type creates
a console application. If this application is invoked from a console,
it executes within the console. If the application is invoked from
an icon, the Run menu, or Windows Explorer, it creates a console
to run in, and destroys the console when the program completes execution.
- The ASP Web Application template is a Web Forms Designer
project, which begins in design mode with a blank Web form. Controls
may be dragged from the toolbox onto the form, and Fortran source code
will be generated to implement the control. The project consists of
an HTML web page that uses Fortran for .NET to provide the code behind.
- The ASP Web Service template is also a Web Forms Designer
project in which the Web Form provides a user interface on the local
machine, with Fortran for .NET powering the application on the server side.
- The Windows Application template is a Windows Form designer project,
which begins in design mode with a blank form. Controls may be dragged
from the toolbox onto the form, and Fortran source code will be generated
to implement the control. This project type compiles into an event
driven Windows application.
- The Setup and Deployment template allows the programmer to
create installation programs that can ease the task of distributing
.NET applications. A setup project packages the files that make up
an application, facilitates the creation of directory structures,
and provides a means of installing and registering assemblies.
- The Database template provides a means of manipulating
databases and designing and executing SQL scripts and queries without
having to create an application.
On-line Integrated Help
The on-line integrated help provides Fortran for .NET installation and getting
started instructions, a Fortran for .NET Users Guide, and a Fortran for
.NET language reference. It also includes the MSDN Library and Visual Studio
SDK help.
Fortran-Smart Editing
The Fortran for .NET language system provides the Visual Studio editor with
the smarts to recognize and color-code Fortran language syntax.
Mixed-Language Debugging
Fortran for .NET code can be debugged in the Visual Studio debugger. If your
application includes procedures written with other .NET languages, the Visual
Studio debugger can seamless step from Fortran for .NET code to the other
language code and back again.
Windows Forms
Windows Forms is the new platform for Microsoft Windows application
development, based on the .NET Framework. This framework provides a
clear, object-oriented, extensible set of classes that enables you
to develop rich Windows applications.
A form is a bit of screen real estate, usually rectangular, that you
can use to present information to the user and to accept input from
the user. Forms can be standard windows, multiple document interface
(MDI) windows, dialog boxes, or display surfaces for graphical routines.
The easiest way to define the user interface for a form is to place
controls on its surface.
Within a Windows Forms project, the form is the primary vehicle for
user interaction. By combining different sets of controls and
writing code, you can elicit information from the user and respond to
it, work with existing stores of data, and query and write back to
the file system on the user's local computer.
Although the form can be created entirely within the editor, it is
easier to use the Windows Forms Designer to create and modify forms.
Fortran for .NET's support for the Windows Forms Designer makes
it easy for you to create Windows applications with Fortran.
ASP.NET Web Forms
Web Forms are an ASP.NET technology that you use to create
programmable Web pages. Web Forms render themselves as
browser-compatible HTML and script, which allows any browser
on any platform to view the pages. Using Web Forms, you create
Web pages by dragging and dropping controls onto the designer
and then adding code, similar to the way that you create Windows
Applications with the Windows Forms Designer.
ADO.NET
ADO.NET provides consistent access to data sources such as Microsoft
SQL Server, as well as data sources exposed through OLE DB and XML.
Data-sharing applications can use ADO.NET to connect to these data
sources and retrieve, manipulate, and update data.
ADO.NET cleanly factors data access from data manipulation into
discrete components that can be used separately or in tandem. ADO.NET
includes .NET Framework data providers for connecting to a database,
executing commands, and retrieving results. Those results are either
processed directly, or placed in an ADO.NET DataSet object in order
to be exposed to the user in an ad-hoc manner, combined with data
from multiple sources, or remoted between tiers. The ADO.NET DataSet
object can also be used independently of a .NET Framework data
provider to manage data local to the application or sourced from XML.

What can you do with Fortran for .NET and why would you want to?
|
What? |
Why? |
|
Mix Fortran and other .NET languages in the same application. |
Libraries written in other languages exist. Use the right language for the right task. |
|
Create Windows user interfaces by dragging and dropping buttons, data entry fields, check boxes, and more. |
Reduce development costs. You want more than a command-line interface. |
|
Create web forms using the same technique. |
You want to make your application and its professional user interface available to the world over the Internet. |
|
Create reusable custom controls, with Fortran, that anyone can use in their Visual Studio environment. |
You know Fortran, you've created custom controls for one application, why not reuse those controls? Reduce development costs. |
|
Create procedures that access or collect data that exist somewhere over the Internet. (XML Web service.) |
Somebody else already did the work of collecting the information. Make it available, accessible. Offer a service. |
|
Create applications that call procedures that access or collect that data. |
Use the data that's available. You can reduce the time to obtain answers. |
|
Create COM objects with Fortran. |
You know Fortran. Use your Fortran procedures from other, non- .NET language programs. |
|
Call, from Fortran, COM objects written in other languages. |
You have access to any COM object that's ever been written. |
|
Create applications that run wherever .NET has been implemented. |
Microsoft's .NET Framework is based on open standards and will be implemented on other platforms. |
|
Create libraries of useful functionality with Fortran (i.e., class libraries) that can be used and extended by any .NET language. |
Don't limit your users to only those who know Fortran. |
|
Easily call Windows APIs from Fortran. |
You know Fortran and want to use the building blocks of Windows. |
|
Code functionality into your web pages using Fortran. |
You know Fortran. It's a way to add smarts to a web page. |
|
Easily read from and write to databases. (ADO.NET - drag and drop database access.) |
It's where you keep your data. |
