How to publish container as tar.gz in .NET

Starting with .NET 8, it’s possible to directly generate a tar.gz container archive. This is particularly advantageous for more complex workflows where activities like scanning the images before pushing them are needed. After creating the archive, it can be transferred, scanned, or incorporated into your local Docker setup. For archiving during publication, integrate the ContainerArchiveOutputPath…

MAUI: How to register handlers in a library

Whether you are developing a custom controls library or simply organizing your solution into multiple project, you will most likely end up in the situation where you want to register some view handlers and services from within a MAUI library. To start off, there’s no such thing as zero-configuration registration. MAUI uses a builder pattern…

How to fix: ‘Point’ does not have a predefined size, therefore sizeof can only be used in an unsafe context

The error you’re encountering is because in C#, sizeof can only be used with types that have a predefined size known at compile-time, and the Point structure is not one of those types unless you’re in an unsafe context. There are two ways you can resolve this. Use unsafe code This would allow the use…

C# Access private property backing field using Unsafe Accessor

One less-known feature of the UnsafeAccessorAttribute is that it also allows you to access auto-generated backing fields of auto-properties – fields with unspeakable names. The way to access them is very similar to accesing fields, the only difference being the member name pattern, which looks like this: Let’s take the following class as an example:…

How to create a 2 column Flexbox layout in React Native

Creating a two column layout in React Native, given a list of items, is quite a common task. This react native 2 column layout can be achieved quite easily using flex. The examble below shows how to achieve the two-column layout with spacing between the elements. This is our view: And this is our style:…

C# ZIP files to Stream

.NET 8 include new CreateFromDirectory overloads which enable you to create a ZIP file without writing them to disk. This is particularly useful in situations where you don’t want to store the zipped resources, you use the Zip content only for transfer. For example: if you were to provide an API allowing multi-file download. That…

.NET 8 performance: 10x faster GetGenericTypeDefinition

.NET 8 brings some neat performance for existing APIs that handle type information. One such API that has seen a significant improvement is GetGenericTypeDefinition. In my benchmarks, the .NET 8 implementation is almost 10 times faster compared to the .NET 7 version. You can run this benchmark yourself if you’d like using BenchmarkDotNet: Or if…

Kebab case – everything about it and more

Kebab case is a naming convention used in programming to format variable, function, or file names by separating words with hyphens (“-“). It is also known as “kebab-case”, “hyphen-case”, or “spinal-case”. For example, if you have a variable representing a person’s first name, you would write it in kebab case as: In kebab case, all…

C# How to update a readonly field using UnsafeAccessor

Unsafe accessors can be used to access private members of a class, just like you would with reflection. And the same can be said about changing the value of a readonly field. Let’s assume the following class: Let’s say that for some reason you want to change the value of that read-only field. You could…

Benchmark results comparing UnsafeAccessor to reflection and direct access. Results show zero overhead for UnsafeAccessor compared to direct access, both clocking in at aroun 0ns, while reflection access takes around 36 ns, or 21 ns when the method info is cached.

.NET 8 Performance: UnsafeAccessor vs. Reflection

In a previous article we covered how to access private members using UnsafeAccessor. This time around, we want to look at it’s performance compared to Reflection, and to see whether it’s truly zero-overhead or not. We’re going to do four benchmarks. If you want to run the benchmarks yourself, you have the code below: Benchmark…

How to access private members without reflection in C#

Reflection allows you to obtain type information at runtime and to access private members of a class using that information. This can be particularly useful when dealing with classes outside of your control – provided by a third-party package. While powerful, reflection is also very slow, which is one of the main deterrents in using…
