If you're still running VB.NET, you might be feeling the pressure to modernize. While VB.NET applications have served businesses well for years, they were designed for a Windows-centric world. With the rise of cloud-native architectures, API-driven development, and cross-platform capabilities, it's time to bring your applications into the modern era.
Migrating from VB.NET to .NET Core isn’t just about flipping a switch or updating a few namespaces. The shift to C# and ASP.NET Core requires structural changes, dependency updates, and a strategic approach to modernization—especially if you want to transition your application to a web-based platform.
Our WebMAP for Angular tool simplifies this process by leveraging AI-assisted automation to convert your VB.NET codebase into a clean, maintainable, and scalable architecture. On the server side, we transition your logic to ASP.NET Core, while on the client side, we utilize Angular with Kendo UI components for a modern, responsive interface.
The differences between VB.NET and C# are both subtle and important. Shallow code conversion tools will create defects in the logic of your application you'll need to find and correct.
There are a variety of tools to convert VB.NET to C#, but they lack the ability to handle most of the complex and subtle syntactic differences between the two languages. Mobilize.Net's patented deep static code analysis tools solve that problem, cutting the time and effort needed to move VB.NET to C#.
Our Free Code Assessment tool gets a good look at your VB.NET code and analyzes the code to get an accurate line count, dependencies and provides insightful reports that can help you with your migration.
This structured approach delivers a seamless migration with minimal disruption, unlocking the power of Angular for your business.
No. WebMAP builds a rich architecture for your application using modern patterns and technologies like ASP.NET Core on the server side, Angular with Progress Kendo for Angular on the client side, with JSON, CSS, AJAX, and more. Some desktop operating system capabilities may not be supportable on a web application (printing, local storage, hardware access, etc). Some manual changes are inevitable when moving from desktop to web; our engineering team will be happy to consult with you on the extent of your needed changes and how to best effect them.
The architecture of the resulting app uses ASP.NET Core or Apache Tomcat as a server, with an Angular front end (HTML plus CSS). We currently use Progress Kendo for Angular for client UI controls. Communication between client and server is JSON and WebAPI.
Yes, currently WebMAP uses Angular with Progress Kendo for Angular; note this is a licensed product and if you use it beyond the trial or evaluation stage you will need to purchase a license.
When you start a migration you have to choose which framework you would like to target.
Most Microsoft and some third party controls are supported. When you run our assessment tool, we can tell you what can and cannot be mapped. Customizations are available to map patterns and controls that are unique to your code.
Our WebMAP automation does not create a responsive app with the resulting migration code. However, since the client is pure Angular with HTML and CSS, it's possible to build responsiveness into the client code post code migration.

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

“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.
