ASP.NET Core 2.1: Razor UI as Class Library

One of the new features of ASP.NET Core 2.1 is, Razor UI as a class library. It makes easier to build and include Razor based UI in a library and share it across multiple projects. A new Razor SDK will enable building Razor files into a class library project that can then be packaged into a NuGet package. You can package your Razor views and pages (.cshtml files) along with your controllers, page models, and data models. Apps can then include pre-built UI components by referencing these packages and customize the UI by overriding specific views and pages. In this post, we’ll see how to create Razor UI as class library and how to reuse it. (more…)

Fix for Blazor error BL9986: Component attributes do not support complex content (mixed C# and markup)

Blazor 0.3.0 was released recently, and I thought of upgrading one of my previously created Blazor CRUD app to the recent version 0.3.0. The Blazor app uses a JavaScript function to control the visibility of the HTML controls present in the Todo list element. The HTML elements inside the list are given a dynamic ID to have uniqueness. Like,

<input id="[email protected]" style="display:none;">

Here, the ID attribute contains C# and HTML markup. Unfortunately, this gives an error BL9986: Component attributes do not support complex content (mixed C# and markup) while compiling in 0.3.0 version. This is a very common use case in any application to manipulate or apply markup based on the server-side data like applying different CSS classes based on a C# variable. In the first place, I was wondering why Blazor is not allowing this and unfortunately, there is not much help available online to fix it. (more…)
