What if I am unable to run Blazor apps in Visual Studio Code?
There are multiple reasons the Blazor application wouldn’t run in Visual Studio Code. Scenario 1: The omnisharp Visual Studio Code is not installed properly in the machine to run the application. Refer to the getting started with Blazor using Visual Studio Code documentation. Scenario 2: Running a Blazor app with F5 in Visual Studio is not supported in omnisharp, which is tracked in this GitHub issue. For now, you can run the Blazor application using the following dotnet CLI command in the application root folder.
Is there any equivalent of HTML.RAW in Blazor?
To render raw HTML in Blazor, wrap the HTML content using the MarkupString type. This allows the HTML or SVG to be rendered as part of the DOM. Refer to the Blazor documentation for more information.
How do you conditionally hide the DOM elements?
DOM elements are hidden using the hidden attribute. You can conditionally use any .NET parameter to set this attribute to hide the DOM elements.
How do you render elements with conditional attributes?
DOM attributes are rendered based on .NET parameters. If the parameter value is true, the attribute is rendered minimized, otherwise it’s not. Refer to the code example to render the checked attribute conditionally.
How do you manually trigger data or UI changes?
By default, Blazor detects changes and reflects them in the UI automatically. However, there might be a situation where we have to manually trigger changes. StateHasChanged informs the component that its state has changed, but it does not render the component. The component will decide when to render itself. You can’t do that in a synchronous method, so you should async your code to give the component a chance to render.
