In day one, you'll see and work with a practical example of going from no code to a deployed feature.

In day two, you'll learn various techniques for keeping an existing code base clean.

This workshop is an in-person, hands-on companion to the book 

Tools and techniques for writing and maintaining a code base that fits in your head.

Developers who have suffered through a few bad projects.

C# code examples are written in a style friendly to developers working in C#, Java, TypeScript, C++, etc. Hands-on exercises are in C# on .NET Core 3.1. You don’t have to be a professional C# developer, but you should at least feel comfortable trying your hand with C#. You can get assistance during exercises, but we will not have time to cover basics of installation, compilation, syntax, and such.

You'll need a development environment that enables you to work with C# on .NET Core 3.1, a Git client, and (for some exercises) SQL Server Express. If on Windows, Visual Studio Community Edition is a great fit. In general, free versions of those application will be sufficient.

Code That Fits in Your Head

.NET

Architecture

Once upon a time, software was simple. You built a website, connected it to a database, and you were done. Then customers started asking for APIs, mobile apps, notification emails, realtime chat… Today, cloud hosting lets us build “elastic” systems – websites that automatically scale up to handle demand; message queues and publish/subscribe patterns to handle spikes in traffic and workload without impacting your end users.

If you’re just starting out with distributed systems design, the possibilities can be overwhelming. APIs, message queueing, REST, GraphQL, gRPC… what should you choose, how does it work, how do you get started?

This workshop gives you a hands-on introduction to the most important messaging patterns used in modern application development. Using C# and .NET, we’ll build a series of small example apps and services, wire them together using these patterns, and discuss how – and when – you’d apply the same patterns in your own applications.

HTTP architectural patterns – XMLRPC, REST, GraphQL

HTTP frameworks: WebAPI, NancyFX, ServiceStack

Working with HTTP APIs: testing and tooling

Exercise: building an HTTP API client and server

Message queueing in .NET – Redis, MSMQ, EasyNetQ

Advanced architectural patterns: CQRS, event sourcing

Exercise: building a pub/sub system using .NET

History of RPC on .NET – SOAP, DISCO, WSDL, WCF

Exercise: high-performance architecture using gRPC

Integrating browsers with distributed systems

Exercise: real-time browser notifications using SignalR

This workshop is aimed at developers with some experience writing applications using C# and Microsoft .NET.

Attendees will be writing and running .NET code during the workshop, so will need a computer running Windows, macOS or Linux, and ideally install the Microsoft .NET SDK from https://dotnet.microsoft.com/download.

Exercises can be done in .NET Framework 4.6+ or .NET Core 2.0+

Introduction to Distributed Systems with C# and .NET

Multi-platform, multi-client, and highly-mobile users bring a new set of challenges, so the approaches of the past are no longer appropriate for modern applications. This two-day workshop is your chance to dive into all things security related to these new technologies. Learn how to securely connect native and browser-based applications to your back-ends and integrate them with enterprise identity management systems as well as social identity providers and services.


.NET Core, ASP.NET Core, MVC, Web APIs, Claims, OpenID Connect, OAuth 2.0, WS-Federation, SAML, JSON Web Tokens, Single Sign-on and off, Federation, Delegation, Home Realm, Discovery, CORS

Social Logins (e.g. Google, Facebook, Twitter, etc.)


Attendees will need to bring a computer with the latest .NET Core SDK and the IDE of your choice (e.g. Visual Studio) installed.

Identity & Access Control for modern Applications and APIs using ASP.NET Core 6

Security

If this sounds familiar, then this workshop is for you. We cover both the theory and patterns of Domain-Driven Design, and connect it to code with hands-on examples in .NET 6.

Where DDD fits in to software delivery and what business problems it addresses

How to craft and enforce a ubiquitous language

The role of refactoring in shaping and reshaping our model

How to define bounded contexts and microservices

Realizing a pragmatic implementation with ASP.NET Core 6 and EF Core 6

We spend day 1 on the theory and concepts of DDD and day 2 applying it to a real-world, complex example with hands-on code exercises.

Domain-Driven Design: Theory and Practice

Microservices

The problem is, leveraging ML with IoT has historically meant backhauling all your sensor data to the Cloud. When the cloud is involved, security is a concern, and in the realm of IoT, security is often a dirty word.

In this workshop, you’ll learn how to leverage the power of Machine Learning on Edge Devices and build secure, cloud-independent IoT applications.
