Hey, I'm Steven a .NET Developer in Switzerland. I am a Microsoft MVP. Also, this blog is open source on GitHub.
Blazor is a beautiful framework for building SPA's. One advantage is that those SPA's feel like native applications. We do not feel that stuff is necessarily loading. But for that we have to keep our code performant.
This guide will highlight some of the techniques to keep your Blazor app running smoothly. We will also cover some more advanced use cases.
In this article I will shade some lights on some of the most used terms which seems very confusing especially for beginners: heap, stack and boxing and unboxing.
Furthermore we will also encounter internet wisdom like:
Value types get stored on the stack. Reference types on the heap
We discuss why this is wrong and what the hell performance has to do with it?
Blazor comes with the option to prerender your webpage on the server. This works for the client-side version as well as the server side version of Blazor.
Let's have a look how does it work and what might be some pitfalls and how can we come around those.
Did you know that you can spend 100x times longer depending how you compare your enums?
Of course we are speaking here in terms of nanoseconds but this story is much more then just numbers. We'll also talk about boxing and unboxing. So let's dive right into it.
Since .NET5 we have the ability to "virtualize" a component.
But what exactly is that and how do we use it?
This blog post will show you a lot of details about the <Virtualize> tag.
Since the introduction of C# 2.0 we have the yield keyword with in combination with the IEnumerable<T> type works as a generator function. We can return elements one by one.
But how does that thing work internally? And what does it have to do with async / await?
Since .NET Core 2.0 the Type ValueTask. It seems that there is a lot of overlap between Task and ValueTask.
So let's have a deeper look into ValueTask. Where should we use it and how should we use it properly? And also: where we should not use is.
You probably are well aware of the Lifetime Scope for ASP.NET Core website.
There are basically 3 scopes: Transient, Scoped and Singleton. Let's have a look how they differ in Blazor Client and Server.
In the blog post we will look a bit into branch prediction. What is it and how can it impact our code?
To explore this we will be Thomas the Signalman, which works at a very busy railroad.
If you ever needed a massive amount of data processed in parallel you might had a look at OpenCL or CUDA. Both are based on a subset of C to describe the program your GPU has to execute.
So let's have a look how we can achieve this in the .NET way. Furthermore I'll give you some insights about GPGPU (General-purpose computing on graphics processing units) in general. Also some limitations and big differences to conventional "CPU"-Programming.
