Removal of .NET Framework 3.5 support

We have decided to remove support for .NET Framework 3.5 and use version 4.6.2 as our new lowest supported .NET Framework version.

In recent years, keeping up with .NET improvements while maintaining compatibility with .NET Framework 3.5 has become challenging. Our codebase has grown more complex, and we’ve also noticed some performance issues in certain scenarios. After doing a comprehensive analysis of the market and our customers’ requirements, we’ve concluded that it was time to say goodbye to .NET Framework 3.5, even though Microsoft will continue to support it until January 9, 2029.

With the removal of .NET Framework 3.5, our components will no longer function in Medium Trust. We believe this shouldn’t be a problem since Microsoft itself no longer recommends using ASP.NET’s partial trust mechanism for isolating applications in a shared hosting environment. The current best practice is to use separate application pools.

Should this change affect you, please contact us, and we will help you find a suitable solution.
