Various software development companies offer support when switching to HTML5, and automated procedures are often advertised. The pure use of HTML5 is described as modern and future-proof. But this is only part of the technical truth.
It is not uncommon for Silverlight applications still in use today to remain in an "evolved state" at some point, as incremental development has only led to limited real improvement. The decision to develop a completely new solution and shut down the old one is often postponed but there is no alternative. Secretly, one hopes for the possibility of taking over "important shares" with know-how or functions that are critical for the business.
The purely automated transfer of such a Silverlight application to HTML5 enables its continued operation. However, further developments (such as the integration of new marketing concepts) remain severely limited. This is mainly due to the fact that the software concepts and philosophies from the heyday of Silverlight sometimes differed fundamentally from today's modern, high-performance and easily maintainable solutions.
