Cloud Application Migration Tools Transform Desktop Applications


WebMAP Boost developer productivity

Boost developer productivity

WebMAP from Mobilize.Net quickly and efficiently modernizes C#/Windows Forms source code to native web applications with ASP.NET Core and Angular. Go from single user desktop legacy application to multi-session, multi-user while maintaining the comments, structure, object names, and UI of your desktop app. 

Revolutionary in its approach and results, WebMAP has been used by companies worldwide to migrate C#/Winforms apps in excess of 1 million lines of code to performant web applications. Compared to a ground-up rewrite, using WebMAP can remove months or even years off the time it takes to make this transition, all while virtually eliminating the risk of breaking the underlying business logic.

Working with Mobilize.Net and WebMAP, your desktop application can be efficiently transformed to a native web application with the same familiar user interface, just running in any browser (thus eliminating the need for retraining), or a completely fresh responsive UI. Modernization can include building microservices, exposing REST services as APIs, and more. 

Check out this before and after migration sample code, you can compile and run it in Visual Studio. See readme for how to build the Angular front end in Visual Studio Code.

Lightweight, performant cloud-native apps

Web apps can be slow, due to control-heavy screens, constant database look ups, and network chattiness. WebMAP single-page application (SPA) apps run light and fast on the server, and at the same time make the client experience rich, responsive, and familiar. 

Cloud application migration tools make it possible. Watch Mobilize.Net WebMAP migrate VB6 code to HTML with Angular and ASP.NET Core.



Automation strips out Windows UI code and converts it to Angular with HTML CSS, and JSON; backend code is converted to ASP.NET Core, leaving business logic intact.
A new web application based on modern, maintainable source code.

  • Code you can read with no legacy artifacts.
  • Code ready for maintenance and enhancements in a fraction of the time – and without the risk inherent in a ground-up rewrite

Mobilize.Net  Your Code New. Again

Mobilize.Net offers valuable technology and services that help customers easily modernize their legacy applications for use on today’s modern platforms and devices program at Microsoft.

- Shawn Nandi, Sr Director, Cloud App Development, Data & AI Marketing

We were able to migrate our VB6 code to .NET using the VBUC license we acquired through MSDN. After the migration only a few things needed manual modification. So your software did a great job and saved us a lot of time

- JMarco Botermans, Owner - Fluke

“Mobilize.Net has a strong track record of building products that successfully automate challenging source code migrations, and this [product] will empower our customers to get up and running on Snowflake sooner.”

- Chris Degnan, CRO at Snowflake

Mobilize.Net seemed the only one that sorted out the details, not only the basic issues of a migration engagement. Its product, the Visual Basic Upgrade Companion, included unique, powerful features, many of which turned out to be very valuable for this specific project, like ADO to ADO.NET conversion and error handling transformation

- Rod Coles – President, Bold Technologies, Ltd

We ran a proof of concept comparing the Visual Basic Upgrade Companion (VBUC) with other VB6 migration tools and we definitely preferred the way VBUC handled the conversion.
