The C# language is great for developer’s productivity and I’m glad for the recent push towards making it more suitable for high-performance applications.
November 1, 2017Nov 1, 201711/1/17System.Tuple types were introduced in .NET 4.0 with two significant drawbacks: (1) tuple types are classes and (2) there was no language support for constructing/deconstructing them. To solve these issues, C# 7 introduces new language feature as well as a new family of types (*).
October 16, 2017Oct 16, 201710/16/17C# 7 finally introduced a long-awaited feature called “pattern matching”. If you’re familiar with functional languages like F# you may be slightly disappointed with this feature in its current state, but even today it can simplify your code in a variety of different scenarios.
October 3, 2017Oct 3, 201710/3/17The Local functions is a new feature in C# 7 that allows defining a function inside another function.
When to use a local function?
The main idea of local functions is very similar to anonymous methods: in some cases creating a named function is too expensive in terms of cognitive load on a reader.
September 21, 2017Sep 21, 201709/21/17In the recent blog posts we’ve discussed invisible part of the object layout in the CLR:
Managed object internals, Part 1. The Layout
Managed object internals, Part 2. Object header layout and the cost of locking
Managed object internals, Part 3.
September 12, 2017Sep 12, 201709/12/17Arrays are one of the basic building blocks of every applications. Even if you do not use arrays directly every day you definitely use them indirectly as part of almost any library.
C# has arrays from the very beginning and back in the day that was the only “generic”-like and type safe data structure available.
September 6, 2017Sep 6, 201709/6/17Working on my current project I’ve faced a very interesting situation. For each object of a given type, I had to create a monotonically growing identifier with few caveats: 1) the solution should work in multithreaded environment 2) the number of objects is fairly large,
May 26, 2017May 26, 201705/26/17The layout of a managed object is pretty simple: a managed object contains instance data, a pointer to a meta-data (a.k.a. method table pointer) and a bag of internal information also known as an object header.
The first time I’ve read about it,
May 17, 2017May 17, 201705/17/17Discussions on reddit, hacker news.
Recently I’ve noticed that the Equal method from our ValueTuple (*) struct generates significant memory traffic (~1Gb). That was a bit of a surprise to me. This struct is well designed and was used pretty heavily in many performance critical scenarios.
