Tag Helpers not properly rendered in ViewComponent

Question

Tag helpers render properly on ALL my razor pages but not in my ViewComponents

For instance:

<label asp-for="MiddleName" class="control-label"></label>

should render as:

<label class="control-label" for="Contact_MiddleName">Middle Name</label>

but instead simply is included in the page as is.

I have searched the web high and low for hours but can't find any solution. Any pointers on what to try?

Answer 1

I guess asking the question here gave me an idea.

In my _ViewImports.cshtml file I have

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

which enables tag helpers on all my razor pages. On a whim I added it to the top of my ViewComponent.cshtml and now it works.

I still don't know why I have to add it to each view component file. If someone can give me the answer for that I'll mark your answer as the correct one.

Answer 2

You have to add in _ViewImports.cshtm tag helper with the name of your project.

@addTagHelper *, ProjectName
