Dependency Injection Scopes in Blazor

The dependency injection system is a big part of how modern ASP.NET Core works internally: It provides a flexible solution for developers to structure their projects, decouple their dependencies, and control the lifetimes of the components within an application. In Blazor – a new part of ASP.NET Core – however, the DI system feels a bit odd, and things seem to work a bit differently than expected. This article will explain why this is not only a feeling but indeed the case in the first place and how to handle the differences in order to not run into problems later on.

Incremental Roslyn Source Generators in .NET 6: Increasing Performance through Harnessing of the Memoization – Part 4

In Part 1 of this series we’ve implemented a simple Incremental Source Generator. Although we looked at all mandatory phases of an IIncrementalGenerator, still, the consideration was quite superficial. One of the biggest advantages of the new API, which makes the Source Generator an incremental one, is the built-in memoization, i.e. caching. To take full advantage from it, we have to make some preparations so Roslyn knows what to cache and how to compare the results of each phase.

Incremental Roslyn Source Generators In .NET 6: Testing Source Generators, Analyzers & Code Fixes – Part 3

This article is the 3rd part of a series about Roslyn Source Generators & co. In the 1st article, of this series, we built an Incremental Source Generator to generate a new property Items of a Smart Enum. In the 2nd article, we added a Roslyn Analyzer and a Code Fix to prevent common mistake(s) and to help out the developers when using this Source Generator. All the code we have written so far was tested manually by executing the code and looking at the outcome. It is time to implement some automated tests to ensure the correct behavior.

Incremental Roslyn Source Generators In .NET 6: Better Experience Through Roslyn Analyzers & Code Fixes – Part 2

This article is the second part of a series about Roslyn Source Generators & co. In the previous article we built an Incremental Source Generator that extends a custom class by creating and initializing the new property Items. This new property returns all items of a Smart Enum. Although the Source Generator is fully functional, I still don’t consider the current state as ‘finished’. During implementation of the Source Generator, we made several assumptions, which means the developers must know the internals to use it properly. If the author of the Source Generator is the only consumer of this tool, then we can leave it as it is. If not, then it would be a bold decision to expect others to have the same knowledge as the author. In this case, I highly recommend adding a Roslyn Analyzer to guide the developers in the right direction.

Incremental Roslyn Source Generators In .NET 6: Code Sharing Of The Future – Part 1

The Roslyn Source Generators, which came with the .NET 5 SDK, are probably one of the best features in the last few years. They allow us to improve the way we share code today by generating it on-the-fly during development instead of shipping fix set of components, helpers and base classes relying heavily on Reflection. With .NET 6 SDK, Microsoft gave us Incremental Roslyn Source Generators for more efficient and resource-saving implementation of Source Generators.

Modular Monoliths With ASP.NET Core – Pragmatic Architecture

Thinking and even recommending a monolithic architecture these days seems antiquated. While a microservices architecture clearly has its benefits, it also comes with drawbacks. Sometimes these drawbacks can be more significant than the benefits and might hinder your development, time-to-market, or your ability to maintain your application.

Token-Based Security: 3 Possible Alternatives To IdentityServer

At least in the .NET space, IdentityServer is a prominent candidate for implementing token-based security in your .NET and ASP.NET applications, server-side or SPAs. After the license change of the popular open-source library, many are wondering if there are any viable alternatives. If you are an existing IdentityServer user, you may want to check out their license model and see if it would be feasible for you to buy a license and just continue with it. Switching the token server to a different solution may not be that easy and cheap.

Better Entity Framework Core Performance By Reading Execution Plans

Both a LINQ query and an SQL statement are descriptions that state which data should be fetched, but not how.. Sure, when reading LINQ or SQL, we can make assumptions about the performance but not in every case. Some queries are either too fancy or too big to grasp, so our predictions may be way too vague if we can make any at all.
