Breaking Apps Apart Intentionally – Visual Studio + Docker + Sprinkles of Azure = Modern Microservices

Dino Esposito
Programming ASP.NET MVC Core

This workshop provides a comfortable learning path to ASP.NET Core that spans over all the topics a developer must know to use the framework and build Web applications. Although completely new under the covers, ASP.NET Core still looks pretty familiar to many because of the close similarity with the ASP.NET MVC programming model.

Developing cross-platform apps with C# using Xamarin

Xamarin is quickly gaining a lot of traction within the Microsoft developer community. Using the same language – C# – we can now create apps which run on iOS and Android, next to only Windows Phone previously. Developers which have been developing using the .NET stack now get the ability to extend their reach onto other platforms, while still being able to use tools like Visual Studio.

In this workshop, we will review the tools, libraries, and best practices for setting up your production monitoring and diagnostic environment.

Warsaw is very well connected, both within Poland as well as internationally.

In the unlikely case that your visa application is refused, we will refund your conference fee in full (requires a consulate statement denying visa). Do you have any questions not covered by the above? Feel free to contact us!

Since the place of service delivery is in Poland, we have to charge VAT on top of the net amount and the "reverse charge" scheme does note apply in this case (it's different from export of services or goods to another EU country). You can, however, reclaim the paid VAT from Polish tax authorities under EU VAT return scheme. More on that here:
