Loading assembly specified in addTagHelper fails when project has razor precompile module

[kirthik]

Add a simple taghelper

public class FooTagHelper : TagHelper
{

}

Create a view and add @addTagHelper "*, WebApplication2" and <foo> tag.
Run the app and it works fine.
Now add RazorPreCompilation code

public class RazorPreCompilation : RazorPreCompileModule
    {
        public RazorPreCompilation(IServiceProvider provider) : base(provider)
        {
        }
    }

and build the app
I am seeing following error

Cannot resolve TagHelper containing assembly 'WebApplication2'. Error: Could not load file or assembly 'Microsoft.AspNet.Razor.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
