WPF Migration to Browser-Based Applications with Modern HTML5

fecher helps you move existing WPF applications to the web. Using a structured, largely automated migration process, we transform them into modern HTML5-based web applications—with a clearly defined project approach and a fixed-price offer. Our proprietary tools and proven methodology provide the foundation for the migration. AI-assisted methods are used where they can meaningfully accelerate analysis and transformation, reduce manual effort, and support testing and quality assurance.

A Future-Ready Alternative to Windows Presentation Foundation

Windows Presentation Foundation (WPF) remains an important technology for developing desktop applications for Microsoft Windows. At the same time, demand continues to grow for browser-based applications that support mobile use and cross-platform access.

WPF provides a robust foundation for sophisticated user interfaces, but its focus on Windows desktop applications creates limitations when applications need to be accessed through browsers or from different devices.

At fecher, we therefore see the migration of existing WPF applications to the web as a forward-looking and sustainable path for companies.

At a Glance: Moving WPF Applications to a Web Architecture

Migrating an existing WPF application to a modern web architecture is generally faster and more cost-effective than developing a new application from scratch. fecher provides an individual proposal tailored to your application and project goals.

• The WPF application is transferred to a modern web application while preserving its business functionality.
• Depending on the existing application and the project objectives, Wisej.NET or Blazor Server is used as the target technology.
• The web application can be deployed on Windows or Linux servers, on-premises, or in cloud environments.
• Existing application components can be reused depending on the selected target technology.
• UI modernization or a comprehensive user interface redesign can be included where required.
• The web application can continue to be maintained and enhanced by the existing development team.
• The existing database can generally remain unchanged.

Wisej.NET or Blazor Server: Two Paths to a Web Application

Different approaches are available for the target architecture. The appropriate technology depends on the existing WPF application and the objectives of the modernization project.

Wisej.NET – Modernization with Proven Application Structures

Wisej.NET focuses on migration with maximum reuse of existing application structures and is particularly suitable when:

• the existing WPF application should be retained as completely as possible
• business logic and application structures should continue to be used with minimal changes
• a rapid migration with manageable project risk is required

Wisej.NET provides the technical foundation for the migration and can be extended according to the specific requirements of the project. Where necessary, third-party JavaScript controls can also be integrated. Developers can continue to focus on the application’s business logic without having to manage HTML, application state, Ajax callbacks, or concurrency directly.

For the automated transformation of WPF applications, fecher uses its proprietary wpfPORTER. The tool supports the conversion of the existing WPF application into a Wisej.NET-based web application and enables the graphical layer to be replaced without requiring the application to be fundamentally redeveloped.

Blazor Server – Redesign with a Modern Web Architecture

Blazor Server focuses on a more extensive transformation of the user interface and application architecture toward modern web concepts and is particularly suitable when:

• the user interface and interaction logic are to be adapted more extensively
• a modern, component-based web architecture is a primary objective
• existing application structures cannot or should not be retained without substantial changes

Blazor Server enables component-based web applications within the ASP.NET Core and .NET ecosystem. Compared with the reuse-focused Wisej.NET approach, the user interface and interaction logic are reimplemented more extensively using Razor components and modern web development principles.

The appropriate target technology is selected based on the existing application, the desired level of reuse, and the long-term development strategy

Proven and AI-Assisted Migration Process

Like all fecher projects, WPF migration follows a proven process with a flexible level of service. During the Evaluation Phase, we work with you to establish a reliable basis for deciding how the application should be migrated. This includes a fixed-price proposal based on the scope and complexity of the source code. The implementation project begins only after the target architecture and project approach have been agreed. Artificial intelligence complements our proven methodology where it provides concrete value. It can support the analysis of existing application structures and dependencies, identify recurring transformation patterns, and assist with testing and quality assurance. Comprehensive testing is performed before completion to verify that the migrated application operates reliably in the defined local, cloud, browser, and mobile environments.

Make Your Applications Future-Ready with fecher

For more than 30 years, fecher has helped companies from a wide range of industries modernize business-critical applications. In addition to migrating WPF applications to the web, our services include VB6 Migration, Web Enabling for WinForms applications, Access Migration, and other application modernization services.

By combining extensive experience, proprietary migration tools, a structured project approach, and targeted use of AI, we provide a reliable and cost-effective path to modern web and cloud architectures.
