Question

Hi,

After upgrading Visual Studio Community 2019 to version 16.10.0, I get this error at runtime
"*

The type 'RazorViewAttribute' exists in both 'Microsoft.AspNetCore.Mvc.Razor, Version=2.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' and 'Microsoft.AspNetCore.Mvc.Razor, Version=2.0.4.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'"

• But, running Visual Studio Enterprise 2019 Version 16.8.4 the app works just fine.

Below screenshot are the pacakges.

Answer 1

Managed to solved it by uninstalling/removing both "Microsoft.AspNetCore.Razor (2.0.3)" and "Microsoft.AspNetCore.MVC (2.0.4)" packages.
