For example, the following code that I use in my blog is using Url.Page() method: var callbackUrl = Url.Page("/Index", null, null, Request.Scheme); But in my unit test, mocking like this will throw …
.NET 5 正式发布已经有一段时间了，其中 Blazor 技术是该版本的亮点之一。作为微软技术的被坑者，年少的我曾经以为 SilverLight 能血虐 Flash，Zune 能团灭 iPod，WP 能吊打 iPhone，UWP 能统一全平台…… 可是后…… 最终步入大龄程序员的我发现，只有陪伴了我将近 20 年的 ASP.NET 还没有完蛋。于是我这两天花了点时间，尝试将我的一个 UWP 小工具用 Blazor 重写，分享给大家。 无法抢救的 UWP “人民币大写转换器” 是我年少无知时开发的小工具之一，它的主要功能有： - 将数字金额转化为大写中文 - 复制结果 - 使用中文语音朗读结果 - 显示参照表 可惜 UWP 不论是充满 Bug 的 SDK，Runtime，还是微软的龟速更新与混乱的规划，都已经无可救药了，是时候给应用找个新家了。 Blazor Blazor 是 .NET …

Some time ago, I successfully migrated an ASP.NET Core Web API project to the latest Azure Function V3, thereby taking advantage of the serverless features of the Azure platform to reduce operation and maintenance costs by 10 times. This article will introduce the key steps and practices in the migration process to help you migrate similar Web API projects. Project background This Web API …
Microsoft often releases updates to .NET Core, usually as security patches. This morning, the .NET Core 3.1.5 update was released. However, Azure App Service's own .NET Core runtime will not be updated immediately, and we would usually wait a few weeks before Microsoft rolls out the update to Azure. For applications with high security requirements, it is urgent to complete the update before …
Background In the ancient days of the .NET Framework, there was a RouteDebugger that outputs routing information for the current page in an MVC or web API app, or sees all the routing information registered in the app. The latest version of its NuGet package is 2.1.5, updated in 2016, from an article by Phil Haack 12 years ago https://haacked.com/archive/2008/03/13/url-routing-debugger.aspx …
"Moonglade", the open-source blog system used by my blog (https://edi.wang), has been around for over a year. At least four community friends have used the system to deploy their own blogs on Azure and Alibaba Cloud. Unfortunately, the system has long lacked Docker support, which is the political correctness of today's world. Recently things have changed, and I successfully made my blog system run …

Windows Forms If you are developing Windows Forms Apps using .NET Core 3.x, there's a built-in API that can …
I rewrote my blog system with .NET Core last year. After more than a year of optimization, the server response time is now 8ms comparing to 80ms when it first went live. This article shares what I have done to make my blog works really fast. In fact, before .NET Core, my old blog system was written by .NET Framework, built from ASP.NET Web Form 2.0 in 2008 all the way up to ASP.NET MVC5 in 2018. …
I upgraded a WinForms App to .NET Core 3.1 these days. It's an open-source on-screen ruler created by Jeff Key in 2004, the original code was for .NET Framework 2.0, I've already upgraded it to .NET Core 3.0 in September this year, it was very smooth without any code change. But this time, .NET Core 3.1 does require some code changes. The project is on my GitHub: https://github.com/EdiWang/ …
