Whizz  is an education company specialising in online services and digital learning strategy. The company’s internal database management application shown below was migrated from Silverlight to CSHTML5.

II was impressed with the level of commitment, technical ability and support from Userware from the very beginning. They immediately understood my problem and worked with me to position the application and its dependencies into a state where they could migrate it. I very much appreciated their level of professionalism and thoroughness and commitment to quality.”

The application uses many of the Silverlight features, including the built-in DataGrid and WCF SOAP communications. The structure of the Visual Studio solution has remained the same. More than 99% of the original C# and XAML code has been preserved:

The application now runs on all modern browsers without requiring users to install any plugin.

“We were able to create an application that worked in all browsers and looked identical to the current one – thus requiring no training or support. We can work in Chrome and Firefox and the staff are very happy.” – Bill McLaughlin, CTO

OpenSilver is a replacement for Silverlight that provides a fast and cost effective path for migration, without compromising the look or functionality. Resulting apps run on all modern browsers without the need to install a plug-in.

The migration works by replacing the Silverlight development tools with the OpenSilver tools (download here). You keep coding in C# and XAML like you did before the migration, thus leveraging the extensive documentation, tutorials, and samples that were made for Silverlight. You can implement or work around missing features by importing equivalent .NET Standard or JavaScript libraries.

Since OpenSilver is fully open-source (source here), based on industry standards (WebAssembly, HTML), and compatible with .NET Standard and JavaScript, it is a durable solution that lets you be self-sufficient and independent for many years to come.

Userware – the company behind OpenSilver – is available to provide professional support and to assist you through your migration, ensuring that all the features of your original Silverlight application work great under OpenSilver.
