Tag Helpers disabled in VS 2015

Question

I am having trouble getting Tag Helpers enabled in my project.

Here is a summary of the project setup:

• VS 2015 RC Community Edition.
• Project.json reference: Microsoft.AspNet.Mvc": "6.0.0-beta4
• _GlobalImport.chtml has @addTagHelper"*,Microsoft.AspNet.Mvc.TagHelpers"

No build errors or warnings.

Must missing something, but I don't know what.

UPDATE:

Seems I am part of the way there. I added @addTagHelper "*, Microsoft.AspNet.Mvc.TagHelpers" to the _ViewStart.chtml. Razor is now processing things like <a asp-controller="Home" asp-action="Summary" title="Manage">TEST</a> as a link with a proper href attribute. However intellisense on not working.

Answer 1

1) In your project.json dependencies, make sure you have these 3:

"Microsoft.AspNetCore.Mvc": "1.0.1",
"Microsoft.AspNetCore.Mvc.TagHelpers": "1.0.1",
"Microsoft.AspNetCore.Razor.Tools": {
  "version": "1.0.0-preview2-final",
  "type": "build"
},

2) In your project.json tools, make sure you have:

"Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final"

3) In Your Views\_ViewImports.cshtml, make sure you have:

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

Then rebuild the project and you should be good to go. (If not try restarting VS.)

Answer 2

After much back and forth I got the intellisense working.

As mentioned in the question update, I needed to add @addTagHelper "Microsoft.AspNet.Mvc.TagHelpers"

Finally, I looked at the NuGet page for tag helpers. I noticed some listed dependencies were not in my project. I added those, restarted VS, and got some intellisense.

Answer 3

Try to add dependency "Microsoft.AspNet.Tooling.Razor": "1.0.0-beta5" to your project.json.

That fixed a similar issue for me.

Answer 4

In my case I needed to deactivate the IntelliSense of ReSharper (9.2) which overrides the TagHelpers.
