GAP AI Migrator automates the migration of .NET Windows Forms applications from desktop to a modern web architecture, using industry standards like ASP.NET Core, Angular, HTML5, CSS, and more. GAP AI Migrator is different from other tools because it creates high quality native HTML5/Angular code, without any use of binaries, runtimes, or browser plugins. As opposed to a manual rewrite, GAP AI Migrator gives customers a jumpstart on a new platform by providing a new fully functional app that can be tuned and extended to take advantage of new features.
With version 5.0, GAP AI Migrator brings big improvements in code readability, app performance, and automation. You can learn more starting here.
GAP AI Migrator migrates Winforms/.NET source code (either C# or VB.NET) from a client-server architecture to a new code base that is architected to be a modern web application. After migration the source code must be compiled, debugged, and deployed on a web server. Because GAP AI Migrator uses automation to transform code, fewer defects are created compared to a manual rewrite. You get a new code base, completely readable and maintainable, using state-of-the art languages, frameworks, and patterns without introducing defects in your business logic. GAP AI Migrator can shave up to 80 percent of the time and cost needed to "webify" a Windows desktop application.
There are many advantages to moving captive desktop apps to a web architecture. Users can run the app on any browser (so virtually any hardware platform). Deployment is simpler, quicker, and cheaper. You can host from public, private, or hybrid cloud. You can implement DevOps, continuous improvement and continuous delivery (CI/CD), and application health monitoring. Rewriting desktop apps into web apps is risky, time consuming, and expensive. GAP AI Migrator changes the calculus to make it possible.
No. GAP AI Migrator 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 assessment tool will tell you how ready your code is to migrate without the need to upload any code. Download the assessment wizard to analyze your desktop source code to find out how ready it is to migrate to cloud native.
GAP AI Migrator relies on contemporary tools like Visual Studio (Community or Enterprise Edition) and Visual Studio Code, as well as many nuget packages. Full instructions are provided with your license.

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 GAP AI Migrator 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.
Many Microsoft and some third party controls are supported. When your 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.
GAP AI Migrator fully supports C# 6.
GAP AI Migrator does not create a responsive app. Responsive interfaces are usually not a good fit for most desktop apps once they are migrated to the web. However, since the client is pure Angular with HTML and CSS, it's possible to build responsiveness into the client code.
The resulting application is “functionally equivalent” to the original application. That means that it will look and act the same as the originating application. Since layout is controlled by cascading style sheets (CSS) you can immediately make modifications to how the app looks on different form factors.
GAP AI Migrator can handle converting C#/Winforms, VB.NET/Winforms, and PowerBuilder.
Yes, we use ASP.NET Core so it can be hosted on Apache Tomcat or IIS.
Desktop infrastructure and web/cloud infrastructure have some fundamental differences and functional gaps. However, we automate as much as possible while providing high quality, maintainable code.
Yes, by using our migration services since the change from your existing authentication/authorization mechanism will have to be custom.
A Web application has a different user paradigm than a desktop app--among other differences, it has to share memory and processor resources with every other session; on a desktop normally the execution thread is supporting only one session. Additionally, the client and back end logic must communicate over a network of indeterminate performance; this can introduce latency in response. Our architecture is designed to make the Web app work as efficiently as possible but tuning may be required to get the best performance.
We have several options here. We can have an OCX/applet or a client app that allows the web app to interact with devices or we can provide a web based solution or in some cases these devices can be connected to a shared server. There are workarounds that vary from app to app.
We are still analyzing the best options for automating the migration. Meanwhile we provide upon request guidance and examples for manually changing your code and we can quote for a migration customization for your particular needs. If your application just uses the Office APIs to read and/or write Office documents, then you can replace the Office APIs by libraries like:
If you need app interaction that might require moving code to the client and using an extension like an OCX, Browser Extension or applet in order to provide communication between browser, Office, and server, we can provide examples of these techniques upon request.
Yes, by default GAP AI Migrator generates a solution based on ASP.NET Core, targeting the .NET Framework 4.5
Please fill-out our talk to an engineer form if you have any technical questions. We'll set up a technical call and clear any doubts you might have.
The trial and assessment are free; an actual migration cost depends on the size of your app. You can find more information HERE.
We use the assessment tool to measure the different PME (properties, methods and events) used by the application and collect some other statistics. We then use that to compare with our tables of currently supported PMEs and features, and we estimate the amount of work to add the missing elements or solve other important challenges detected during assessment. That provides a ballpark number.
The goal of the project is a functionally equivalent version of your current application but moved to the new platform and architecture. The standard methodology assumes our clients deliver us a set of test cases along with the source code of the application that we will migrate. Tests which run on the current app will pass on the new app; however, in the cases where the specific test doesn’t map exactly to HTML (for example, the test assumes the app is connected to a local hardware device), new replacement tests must be devised. Our QA department will run whatever test suites you give us.
Certainly. We have to do some basic validation after building the app that it runs, but you can have your own QA department handle most of the work and log bugs in our database. Also, we have different engagement models where we can do just basic testing on the application or where we can execute the full set of test cases. Your QA team involvement will depend on the engagement model we define for the project.
Yes, we work with this situation frequently. We can put engineers on site at your facility, and also we can use a VPN to access your code on your source control system.
It definitely gives them benefits. End users get easier installation as well as the major benefit of mobility. They will be able to access the system from their preferred browser and even from their tablet or phone.
Yes. As migration experts we are already used to that reality and the Migration Blueprint will establish how, when, and how often we will integrate application changes and any other steps.
We will happily keep your new app current for you. Please contact us at info@wearegap.com for more information.
Yes, we can provide web hosting, IaaS, etc. with major cloud vendors so you don’t have to worry about hardware, uptime, deployment, or support.
HTML5 makes it possible to move most native functionality to a native web application, easily deployed in the cloud.
