TL;DR: Another Serilog Expressions by example post, showing how to produce newline-delimited JSON logs from Serilog events. Newline-delimited JSON is a useful format for structured logs that will be read by other applications. Serilog’s built-in JsonFormatter implements this, but to my eyes, its output is awkward and verbose. The newer CompactJsonFormatter and RenderedCompactJsonFormatter in Serilog.Formatting.Compact produce cleaner JSON, and that format is supported by other tools in the Serilog ecos...

Introduction Today I would like to suggest a less-common but in my opinion a much better way to organize our codebase. Meet the Feature Folders.Problem For ages we have been (at least in the .NET environment) used to thinking about our code structure taking into account the technical aspects. For example MVC application project templates assume the division our objects into separate directories – Controllers, Views, Scripts and so on. We can see the same in many tutorials. If we need add new feature, f...

Fuzzy search allows finding strings that match the pattern approximately. It is a feature needed in almost every app, but it can be a little problematic to implement. We will focus on EFCore PostgreSql provider as it is free and seems to be the most popular choice nowadays (for me at least). First, our EFCore project needs this package: Npgsql.EntityFrameworkCore.PostgreSQL.FuzzyStringMatch Then, we need to register it with our DbContext, so let’s navigate to Startup.cs and edit our registration like s...

byAnkit VijayonJun20,2021Background Azure Cosmos DB SDK 3+ for SQL API replaced Azure DocumentDB SDK a couple of years back. DocumentDB used Newtonsoft Json.NET for its serialization. However, with the growth of .NET Core and the introduction of shiny new System.Text.Json, the team wanted to reduce exposure to Newtonsoft. So the idea was in future, with CosmosDB SDK 4, System.Text.Json would replace Json.NET. The unfortunate side-effect of this was that we do not have an easy way to supply custom JSON...

When a new project is in the start-up phase all models are relatively small, simple, and do not have a lot of relations. This makes the tests easy to arrange and also easy to read. Because the team ...
Converting an enum value to a string using the ToString() method is expensive. In general, the performance impact is negligible. But when you call the ToString method thousands of times per second, saving a few milliseconds is important.

While this post is addressed to F# .NET developers, it introduces much wider concepts starting from hardware architecture to overall .NET runtime and JIT compiler optimizations. It shouldn't be a surprise - optimizing the application performance requires us to understand the relationships between our high level code and what actually happens on the hardware. There's a popular opinion that F# code must be slower than equivalent C# code. This opinion is mostly false, however it comes with some rationale. ...

🚨 Quite often, to make our code simpler, we're trying to make our code more reusable and generic. I wrote an article with a warning that "generic" does not mean "simple". I did that on the example of #CQRS code evolution. Beware and have a read!

Ben June 15th, 2021 Bing runs one of the world’s largest, most complex, highly performant, and reliable .NET applications. This post discusses the journey and the work required to upgrade to .NET 5, including the significant performance gains we achieved. This application sits in the middle of the Bing architecture stack and is responsible for much of the coordination among thousands of other components that provide results for all queries. It is also at the heart of many other services outside of Bin...

Building modern APIs require a lot of things to make them reliable, observable, and scalable. In no particular order, here are some of them that help you build better APIs:1. Healthchecks Healthchecks are important in making sure that we know when anything happens to our APIs. We can setup dashboards to monitor them and setup alerting to let us know when one of the APIs is unhealthy. They are also important when deploying your apps to kubernetes. Kubernetes can monitor healthchecks of your APIs and auto...
Laurent June 10th, 2021 Today, I’d like to show dotnet how to run your own .NET application on a Micro Controller Unit (MCU) on a simple battery for multiple years. I’ll build an application that will read the temperature and pressure on a BMP280 sensor connected to an ESP32. The core idea is to be run on a small solar panel charging a LiPo battery. I will as well present two real case scenarios, both running .NET nanoFramework, one on STM32F7 processor and the other one on a TI CC1352R. I’m Laurent E...
