WPF Bar Chart rendering with skia

WPF Chart with SkiaSharp SkiaShrap graphics library renders gradients very very smooth and I love it on WPF (as opposed to natural way of creating gradients) it also scales nicely when a window resizes without extra code;

Diagnostic Tools

© Andrey Akinshin 2019 Andrey Akinshin Pro .NET Benchmarking https://doi.org/10.1007/978-1-4842-4941-3_6 .NET Diagnostic Tools Andrey Akinshin 1 (1) Saint Petersburg, Russia If all you have is a hammer, everything looks like a nail. — Abraham Maslow Benchmarking is only one of the performance investigation steps. In this chapter, you will find a brief overview of the some important diagnostic tools that can be useful for the whole investigation. We will learn the following kinds of tools: Benchmarking harness This tool automatically benchmarks the specified method and displays corresponding metrics. It tells you how much time it takes to perform this method, but it doesn’t always tell you why you have such values. Performance profiler This tool measures performance metrics for each called method inside an application. It tells you where the performance bottleneck of the application is and allows exploring performance profiles w...

Reading Large Data files in WPF with IAsyncEnumerable

Producing and consuming Async sequences Reading Large Data files in WPF As soon as you type new Thread() , it’s over; your project already has legacy code. An asynchronous foreach will ask the collection object for an enumerator, and will repeatedly ask it to advance to the next item, executing the loop body with the value returned by Current each time, until the enumerator indicates that there are no more items. The main difference is that the synchronous MoveNext has been replaced by MoveNextAsync , which returns an awaitable ValueTask <T>. (The IAsyncEnumerable <T> interface also provides support for passing in a cancellation token, although an asynchronous foreach won’t use that itself.) To consume an enumerable source that implements this pattern, you must put the await keyword in front of the foreach. You can also return an IAsyncEnumerable<T> . Code below shows both implementation and consumption of IAsyncEnumerable<T> in actio...
