I recently started using Refit in a project and its a really nice way to consume rest endpoints. Once you set it up, all you have to worry about is making a call against a interface and Refit will do all the work for you. As an example, imagine that I have a person REST […]

We recently started using MediatR in a project and its a great way to make your services simpler as requirements grow. I want to show a simple example to give an idea on why you would use it. I’ve created a person controller that has a search endpoint that in theory will get a Person […]

An interesting class that is useful to know about but you most probably won’t directly use is AsyncLocal. It stores data local to the async flow. This means that if a method further down the chain changes the underlying value, the change will only apply to that and its children. A potential use case might […]

I want to convince you to try Property-based testing in your projects. Its a really powerful approach when combined with classic unit testing. When we write a unit test we generally use what they call example based testing. What this means is that we create an expected response and run our test to confirm that […]

Following from my previous post on getting paged data from twitter, I thought it would be interesting to use ML.NET to do a little analysis. A common problem solved with machine learning is doing sentiment analysis on text to evaluate how positive or negative something is. To solve this problem with ML.NET really isn’t that […]

A really nice feature in C# 8 is async enumerables. A popular use case is if you want to consume paged data and potentially aggregate each page of data without having to get everything first. Previously the consuming code would have to handle the paging but now your method can just enumerate over the IAsyncEnumerable […]

With more and more companies moving to the cloud, the idea of serverless execution of your code has more and more appeal. AWS has Lambda and Azure has Functions. The idea is the same: You give them a method that you want to execute and the provider works out the scaling. As you get more […]

We all agree that we want to have tests that cover as much of our application as possible. Right? The general approach with ASP.NET applications has been to extract meaningful business logic out of your controllers. Pretty much everything that needs to be tested would be injected with an interface so that its easy to […]

When looking at performance of an application, there is a trade off between when you should be using value types and when you should be using reference types. People often talk about minimizing allocations to the heap for reference types but allocations themselves are actually very quick. The reason why its an issue is that […]

A new feature in C# 8.0 and .NET Core 3.0 is that of default interface members. The motivation for it is where authors of a public interface would like to add functionality to an existing interface but don’t want to force all the consuming code to implement it. You are able to add a default […]
