Blazor Web Application Development

Let's break down what Blazor is and why it's great for building web applications

A piece of cake, used to breakdown Blazor development with a cake baking analogy.

Blazor is like having different ways to bake a cake, but for making web applications. Instead of just one method, you can pick and mix different ways to build and show each part of your website. This helps make sure everything works just right!

There are a few ways to build and show web pages with Blazor:

Server-side Rendering

This is like having someone else bake the cake and then bringing it to you. It's really fast because you don't have to do much work on your computer. Great for pages that need to load quickly and don't have lots of moving parts.

Streaming Rendering

Imagine getting a basic version of the cake first and then getting the icing later. With streaming rendering, you can see and use the page quickly while the rest is still loading. Perfect for pages that need fresh data before they can show everything.

Server Mode

It's like having someone help you decorate the cake as you want it. The server helps your computer make the page interactive without doing too much work itself. Good for pages that need to react to what you're doing in real-time.

WebAssembly Mode

This is like your computer baking and showing the cake all by itself using tools it got from somewhere else. It's great for making pages that work really smoothly and interactively, especially for apps that need to be fast.

Auto Mode

Imagine starting to bake the cake with help, and then your computer takes over. It's quick to start, then your computer does most of the work. This mode gives you a fast start and then a really nice interactive experience.

Why does this matter?

With Blazor, you can choose the best way to build and show each part of your website, making it smooth, fast, and fun to use. And with the new "Auto" mode, it's like having a smart helper that does the right thing automatically!

Now, imagine going on an adventure in a jungle.

Having someone who knows the way makes sure you get there safely and enjoy the trip. That's where experts like us come in with Blazor. We are like your guide through the jungle of web app development!

We know all about Blazor and can help you build amazing web apps without getting lost in all the technical stuff.

Blazor Mobile Development

Let's explore how Blazor is the perfect technology choice for developing mobile applications

Think of .NET MAUI Blazor Hybrid apps like having a special toolbox for building apps that work on your phone. It's a mix of two cool technologies, .NET MAUI and Blazor, that lets you create mobile apps that are fast and work smoothly.


This is like a magic toolkit for building mobile apps. It helps you create apps that work on different types of phones, like iPhones and Androids, without having to write everything from scratch.


Just like we talked about above for websites, Blazor helps you build interactive parts for your app. It lets you use the same skills you know from making websites to create cool features for your mobile app.

So, a .NET MAUI Blazor Hybrid app is like having this powerful toolbox that combines the best of both worlds:

You get the flexibility and power of .NET MAUI to build apps that work on any phone.

You can use Blazor to make your app interactive and fun to use, just like you would for a website.

In the jungle of mobile app development, Assemblysoft and Blazor are your trusted partner, guiding you through the challenges and empowering you to reach new heights.
