September 5, 2018Sep 5, 201809/5/18One of the best traits of a well-designed system is composability. Large systems are complex and hierarchical and one of the best ways to fight accidental complexity is to compose a system from smaller components. You write and test each component independently then you glue them together to achieve a higher-level behavior.
Performance implications of default struct equality in C#
July 17, 2018Jul 17, 201807/17/18If you’re familiar with C#, then you most likely heard that you should always override Equals and GetHashCode for custom structs for performance reasons. To better understand the importance and the rationale behind this advice we’re going to look at the default behavior to see why and where the performance hit comes from.
Dissecting new generic constraints in C# 7.3
June 12, 2018Jun 12, 201806/12/18During the last Build conference, Microsoft has announced the next version of Visual Studio with C# 7.3 support. This is yet another minor language update with some quite interesting features. The main change was related to generics, starting from C# 7.3 there 3 more constraints: unmanaged,
Avoiding struct and readonly reference performance pitfalls with ErrorProne.NET
May 3, 2018May 3, 201805/3/18As you may know from my previous posts “The ‘in’-modifier and the readonly structs in C#” and “Performance traps of ref locals and ref returns in C#”, structs are trickier then you might think. Mutability aside, the behavior of readonly and non-readonly structs in “readonly”
Performance traps of ref locals and ref returns in C#
April 11, 2018Apr 11, 201804/11/18The C# language from the very first version supported passing arguments by value or by reference. But before C# 7 the C# compiler supported only one way of returning a value from a method (or a property) – returning by value.
Nullable types arithmetic and null-coalescing operator precedence
March 30, 2018Mar 30, 201803/30/18Here is a simple question for you: which version of a GetHashCode() is correct and what performance impact does the incorrect version have?
The ‘in’-modifier and the readonly structs in C#
March 7, 2018Mar 7, 201803/7/18C# 7.2 got two very important features for high-performance scenarios — the readonly structs and the in parameters. But to understand why this additions are so important and how they’re related to each other we should look back in history.

The performance characteristics of the async methods in C#.
One user scenario to rule them all.
Almost every non-trivial behavior of the async methods in C# can be explained based on one user scenario: migration of the existing synchronous code to asynchronous should be as simple as possible.

In the last two blog posts we’ve covered the internals of async methods in C# and then we looked at the extensibility points the C# compiler provides to adjust the behavior of async methods.
