Deciding Which Technologies and Tools To Use

When designing your application, you may need help choosing between different technologies or approaches. This page summarizes the choices and provides links to more information about application development with Visual Studio and the .NET Framework.

Without an Interface

Executable

Library

XML Web service - XML Web services are applications that can exchange interoperable messages in a loosely coupled environment, using standard protocols such as HTTP, XML, XSD, SOAP and WSDL. XML Web services can be accessed from a Web application, a Windows desktop application, or another XML Web service - for details, see Programming the Web with XML Web Services. To learn more about development with Web services in the Distributed System Designers, which are part of Visual Studio Team Edition for Architects, see Overview of ASP.NET Applications on Application Diagrams.
.NET component - for details, see Component Authoring

Create a Distributed Application

For a step-by-step example, see Walkthrough: Creating a Distributed Application and Designing Web Services Walkthroughs.

Create a Smart Device Application

Develop Windows CE- and Windows Mobile-based rich-client applications that run on devices such as Smartphones and Pocket PCs. For more information, see Smart Device Development and Design Considerations for Smart Device Development.

If you are targeting the browser on a cell phone, PDA (personal digital assistant), or pager, then use Mobile Web Forms - for details, see Creating ASP.NET Mobile Web Pages.

Create a Data-centric Application

If you ...

Are navigating between multiple, discrete tables of results ...
Are manipulating data from multiple sources (for example, from different databases, from XML files, spreadsheets, and so on, all in the same dataset) ...
Are exchanging data with other applications ...
Are reusing the same set of rows and intend to cache them (for example, sorting, searching, and filtering cached results) ...
Are doing a lot of processing per row ...
Are manipulating the data using XML operations such as XML transforms or XPath ...
Want ease of programming ...

Then use a dataset - for details, see Datasets in Visual Studio Overview.

Otherwise, use direct access (data commands and data readers) - for details, see Recommendations for Data Access Strategies.

For example, you would use data commands and data readers for:

Performing DDL commands
Performing updates or deletes based on a selection criteria
Programmatically inserting records that are not based on user interaction
Calling stored procedures to execute logic inside the server
Retrieving scalar values from the database
Processing a set of results in a forward only manner without updating and without caching the results
Processing a set of results too large to fit in memory

Web-based Data Applications

For details, see Creating Visual Web Developer Data Applications.

XML Web services are applications that can exchange interoperable messages in a loosely coupled environment, using standard protocols such as HTTP, XML, XSD, SOAP and WSDL. An XML Web service can be accessed from desktop applications (Windows Forms), Web applications, or other XML Web services. For details, see Programming the Web with XML Web Services.

Windows Forms-based Data Applications

Use Windows Forms - for details, see Creating Client Data Applications.

If you ...

Are performing DDL commands ...
Are calling stored procedures to execute logic inside the server ...
Are retrieving scalar values from the database ...
Are processing a set of results in a forward-only manner without displaying, updating, or caching the results ...
Are processing a set of results too large to fit in memory ...

Then use direct access (data commands and data readers) - for details, see Recommendations for Data Access Strategies

Otherwise, use a dataset - for details, Datasets in Visual Studio Overview.

For example, you would use a dataset if you:

Are binding results to a form to let the user view, insert, update, or delete records
Are navigating between multiple tables of results
Are manipulating data from multiple sources (for example, from different databases, from XML files, spreadsheets, and so on, all in the same dataset)
Are exchanging data with other applications
Are reusing the same set of rows (for example, sorting, searching, and filtering retrieved results)
Are manipulating the data using XML operations such as XML transforms or XPath
