Production Xamarin and .NET Core 3.0 Preview Apps Get Security Boost With Dotfuscator Pro 4.39

Dotfuscator Pro 4.39 adds Xamarin anti-tamper controls and early support for .NET Core 3.0 Preview 1 while dramatically simplifying project integration. 

CLEVELAND, OH — December 19, 2018 — Dotfuscator 4.39, available for download now includes Anti-tamper controls for Xamarin.Android. This feature adds to the growing list of run-time detection and response features that have rapidly emerged as standard controls required for every Android app processing sensitive information or secure transactions.

This release comes less than three weeks after Version 4.38 dramatically simplified the configuration of Dotfuscator within Xamarin projects and just a few months after Dotfuscator added Rooted Device detection and defense controls.

“Developer research has shown that a significant percentage of Xamarin.Android development teams behave almost identically to their .NET Desktop development counterparts rather than, as one might expect, Java Android developers,” said Gabriel Torok, CEO of PreEmptive Solutions. “Dotfuscator gives them the tools to defend against Android-specific vulnerabilities like rooted devices or tampering without having to learn Android internals – one of the reasons most developers move to Xamarin in the first place.”

Dotfuscator Professional 4.39 also offers early support for Visual Studio 2019 Preview 1 and in particular .NET Core 3.0 Preview 1. “As we have since 2003, Dotfuscator continues to add cutting edge features and offer timely support for cutting edge platforms and frameworks,” Torok continued.
