.NET ships a nice StringBuilder since the dawn of time or at least since the beginning of the framework itself. The intention is simple: If we need to concatenate a lot of strings we can't rely on the + operator as we introduce a lot of unnecessary allocations plus it is slow! That is where the StringBuilder jumps into the picture.

Why is that? Why is the StringBuilder better? And can we do better? Spoiler: Yes!

In our Blazor components we often call a repository or web API which takes some time. So it is nice to indicate to an user what the current state is. That is why we will create a small indicator even with steps to indicate how far we are in the progress.

This is the last part of the series (for now 😄). In the last. Two parts are missing:

Drag and Drop the items from one lane to another
Save and load the state

And exactly those two things we will tackle. I also will give a small conclusion of my journey.

In the forth part we will take care of our newly created todo item. Until now we clicked on a button and that's all. Sure we have a nice form where we can enter the basic information, but that is all.

The time has come to put our element into the respective swimlane. We will also learn how to add further nuget packages to our project.

A Trie is a common data structure used for example for auto completing words. We will discover how to built our own Trie and check how fast he competes against a "normal" Hashset.

Also we will build a TypeAHead input component which automatically offers us some suggestion based on our input. Of course, we will use our newly created Trie.

In the third part of our small mini series: "Building an todo app with the Uno Platform" we will dive deeper into creating a modal dialog where we can enter the details of our todo item. We will see how we can import additional Nuget packages and how we can leverage validation.

This is the second part of our small mini series, where we build a todo app Kanban style with the UNO Platform. In this episode we are laying some ground work as well as defining all of our requirements we want to achieve.

We will slowly start creating our first components and make everything work smoothly together.

This is the beginning of a mini series shedding some lights on the UNO Platform. The UNO Platform enables us to write code once and run it on a wide range of platforms (Windows, MacOS, Android, Linux, ...). So let's have a look at this. To do so we will create a small Todo App Kanban-style so we can organize our thoughts and work 😉

SSE stands for Streaming SIMD Extensions. What does that exactly mean and how can we leverage that in our C# code?

This blog post will shed some light on this topic. Also we make a small comparison to PLINQ.

The decorator pattern is a common pattern in object oriented languages. It allows us to add behavior to an individual object without changing the object itself.

We will exactly that with a repository. We introduce a caching layer via the decorator pattern.
