Wonder if enterprise Blockchain development can become a thing ?

Fasten your seatbelts, in this session I will show you how to build your own custom Blockchain using Parity Substrate, an open-source toolbox for innovative startup & companies.

After a brief intro on the Blockchain development landscape , we will discover the architecture of Substrate, its peer-to-peer communication stack, its core runtime modules, the ink! language for smart contracts, and the inter-chains interoperability features (para-threads / para-chains).

We will then write a custom runtime module using the Rust programming language, connect it to our node and run our own chain !

Relax! I'm not here to break your software. But I am here to show you how you can break the software you develop without changing the actual code!

Now, I hear you thinking: "Why on Earth should I do this? I have unit/integration/... tests"

Ah, yes, you have tests. Tell me, do you test what happens if a third-party service goes down? Or takes a lot longer to respond when that service hits its busiest time of the day?

Or what would happen if you tried to write data into a SQL database that has no more disk space?

All of these - and more! - cases can be discovered early, during development time. And I'll gladly show you how.

Unbounded data streams are becoming more and more ubiquitous, even more so with rise of connected IOT devices. This means large volumes of data that need to be captured, processed and analyzed. Unfortunately loads of data takes time to analyse and is expensive to store. And what if your data stream needs to be analyzed in real time? This type of data will tell you what is happening “right now” such as nr of ppl reading your blog, people watching a certain product or which hashtags are trending right now? These might seem to be “nice to have” features, but in reality, they are essential. Real-time data holds extremely high value for businesses, but it has only a certain time-window after which it loses its value. This talk will give you a basic understanding of streaming and how to use it.

I’m completely blown away by this new Blazor technology from Microsoft and want demonstrate my experiences with this magic. Blazor is a gamechanger by providing us a very productive development stack for building frontend for web apps. The ability to reuse your C#/.NET skills for building fronted, browser-based UI is a real value for every development team. Discover with me the simplicity to create HTML based UI in C# and see which 3th party UI components for Blazor are available. In this session I’ll show you a complete Blazor based application in C#.

For years, we have been running builds in platforms such as Jenkins, Teamcity or TFS and have done this based on predefined templates. This makes it easy to scale up in a homogeneous enterprise development landscape. However, .Net and front end application development has transformed rapidly in recent years, with new technologies and frameworks being introduced on a regular basis. Supporting development teams with a more flexible build template platform therefore becomes a critical success factor. In this session, we want to share our experience with Cake (www.cakebuild.net) to do just that, and provide the right balance between centralized guidance while not limiting teams to extend or tweak their builds.

Graph databases aren't exactly new but aren't used as often as our regular relational databases. So what exactly are graph databases, why would I use them and how can I integrate them in my .NET application?

ML.NET is a free, cross-platform and open source machine learning framework designed to bring the power of machine learning into .NET applications. In this session we explore the capabilities, pitfalls, and alternatives of running full machine learning scenarios on your local .NET stack: from defining and training a model, to evaluating, deploying, and eventually running it.

The session targets a C# developer audience, but there will be takeaways for business analysts and data scientists too.

You probably know how to secure your API with access tokens, but did you know you can use reference tokens to improve security? The token exchange standard for delegated access? A custom grant for API to API access? And what about improving client authentication for those use cases where clientid & client secret don't cut it anymore?

In this in-depth session we'll cover all of these topics, extensively using IdentityServer4 in the process. Note that some previous knowledge on OAuth2 and OpenID Connect is a must.

The core of every application is it's data. Even in a brave new microservices world, data is key. I built my own REST services, tried OData for a while, but kept wondering is this it? Shouldn't there be a better solution out there for me? Until I discovered GraphQL, the data query and manipulation language created by Facebook, and felt in love with it's simplicity, power and flexibility. In this session I'll explain the basic building blocks of the GraphQL language, why you should use it and share lessons from hands-on experience. You'll leave this session with everything you need to know to get started with GraphQL in your ASP.NET(Core) applications.
