Experimenting with OData in ASP.NET Core 3.1 - OData
A lot of developers have asked me recently about OData compatibility with ASP.NET Core 3.0 and again with .NET Core 3.1 after it’s very recent release. This demand became more and more critical with the recent announcement from the .NET team around .NET Core 2.2 reaching the end of its life on Dec 23rd of this year. And because of all of that, the OData team at Microsoft have been working diligent

個人的に、前々から「T4 は将来性が見えなさ過ぎてもう使うのやめたい」と言い続けていたわけですが、 最近ようやく自分が保守している T4 を全部別の手段で書き換えたので、 今日はそれの話。 T4 (Text Template Transformation Toolkit) テキスト テンプレートというと、ひな形的なテキストを簡易な文法で生成するようなものです。 例えば、 public static bool TryParse(this string s, out {{T}} x) => {{T}}.TryParse(s, out x); みたいな文字列の、{{T}} のところに bool, byte, int, double を与えて、 public static bool TryParse(this string s, out bool x) => bool.TryParse(s, ou

2019年はWPFにとって多くの意味でインパクトのある話題のある年となっています。その中でも次の二つはもっとも大きな影響を私たちに与えるでしょう。 9月に正式にリリースされる.NET Core 3.0でWPFがサポートされる事となった .NET Frameworkのメジャーバージョンが最新の4.8で最後のメジャーバージョンであると告知された これから継続的にWPFアプリケーションに取り組んでいくうえで、.NET Core 3.0への移行は免れません。しかし新規開発ならまだしも、既存のアプリケーションを移行することは現実的なことなのでしょうか？ そこで本ハンズオンでは、実際に.NET Frameworkで構築したアプリケーションをもとに、.NET Coreへ移行していただき移行の「感覚」を理解していただこうと思います。

In our last post, we showed you how you can debug into the framework and dependencies that was produced with Source Link. In this post, we’ll show you how to add Source Link to your projects. This is beneficial both for public and internal projects.

protocolbuffers/protobuf#7645 adds a new API for creating ByteString instances. If you know the underlying data won’t change, then use UnsafeByteOperations.UnsafeWrap to create a ByteString without copying the underlying data. This is very useful if an app works with large byte payloads and you want to reduce garbage collection frequency. var data = await File.ReadAllBytesAsync(@"c:large_file.json
Probably the most impactful feature of C# 8.0 is Nullable Reference Types (NRTs). It lets you make the flow of nulls explicit in your code, and warns you when you don’t act according to intent. The NRT feature holds you to a higher standard on how you deal with nulls, and as such it issues new warnings on existing code. So that those warnings (however useful) don’t break you, the feature must be e

Customizing Trimming In the last blog post, we talked about how trimming in .NET 5 has been expanded to be able to trim types and members that are detected as not being used in the application, and that detection uses static analysis, it doesn’t run the code for the app, so it doesn’t know which branches won’t be taken or what values variables will actually contain at runtime. The trimming can eit

What is trimming One of the big differences between .NET Core and .NET Framework is that .NET Core supports self-contained deployment – everything needed to run the application is bundled together. It doesn’t depend on having the framework separately installed. From an application developer perspective, this means that you know exactly which version of the runtime is being used, and the installati
