Ian Griffiths, Technical Fellow at endjin, .NET MVP, and author of Programming C# (O'Reilly), returns to On .NET Live to demo Rx.NET with live ship-tracking data from Norway's AIS network and walk through the major changes coming to the Reactive Extensions ecosystem in v7.<\/p>\n
In this episode:<\/p>\n
Ian Griffiths<\/a>, Technical Fellow at endjin, shares the latest updates on the Reactive Extensions for .NET<\/a> (AKA ReactiveX AKA Rx.NET). Learn about the new features in Rx 6.1, what .NET 10 means for the project, and the significant packaging changes coming in Rx v7.0 that finally solve the long-standing deployment bloat issue.<\/p>\n In this talk:<\/p>\n In this talk, Ian Griffiths<\/a> dives into the new implicit conversions introduced in C# 14, designed to make span types more natural to use.<\/p>\n He discusses how this change enhances performance, simplifies method signatures, and enables more powerful extension methods. However, Ian also warns about potential compatibility issues with older libraries and provides advice for library authors. He concludes with technical examples and solutions to common problems caused by these new features. Essential viewing for C# developers looking to leverage spans in their code more effectively.<\/p>\n In this talk, Ian Griffiths<\/a> explains how C# 14's new field-backed properties feature can save you from metaphorically falling off a cliff when you need more flexibility beyond automatic properties' basic functionality.<\/p>\n He demonstrates the use of this feature to customize property setters without losing the simplicity and support of automatic properties. By allowing you to refer to the compiler-generated field inside get or set methods, C# 14 reduces verbosity and maintains code clarity and organization.<\/p>\n Learn how this small but impactful enhancement can improve your C# coding experience.<\/p>\n C# 14 introduces new directives that transform C# into a true scripting language. In this video, Ian Griffiths explains how the .NET 10 SDK now lets you run a single C# source file directly\u2014no project file required.<\/p>\n What you'll learn:<\/p>\n Contents:<\/p>\n In this video, Ian Griffiths<\/a> introduces the new He explains the peculiar behaviour of exception stack traces that led to the creation of this operator, following feedback from Adam Jones<\/a>.<\/p>\n The video delves into how exception state is managed in .NET and the specific issues that arise when exceptions are reused without being re-thrown. Ian demonstrates the problem with code examples and shows how the new operator resolves it.<\/p>\n Full documentation is available at Introduction to Rx.NET<\/a>.<\/p>\n In this episode, Ian Griffiths<\/a> introduces the new He discusses the new functionalities, including a new Ian explains that Full documentation is available at Introduction to Rx.NET<\/a>.<\/p>\n In this video, Ian Griffiths<\/a> introduces the new He discusses the purpose and functionality of this operator, which allows users to stop an infinite source when a cancellation token is signalled.<\/p>\n Ian acknowledges the contributions of community members Nils Aufschl\u00e4ger<\/a> and Daniel Weber<\/a> in shaping and developing this feature. Through a simple example using the Interval operator, Ian demonstrates how this new operator works and explains its benefits.<\/p>\n Learn how to manage infinite sources effectively with the new Full documentation is available at Introduction to Rx.NET<\/a>.<\/p>\n\n

He demonstrates the method in a console application, comparing it with the traditional CompositeDisposable approach, and highlights its ease of use for handling observable subscriptions.<\/p>\n\n
