I just updated to Visual Studio release v17.4.0 and this bug is affecting all projects as I was running net6.0…

Editing the project file helped me

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <LangVersion>Preview</LangVersion>
    <EnablePreviewFeatures>True</EnablePreviewFeatures>
    <GenerateRequiresPreviewFeaturesAttribute>True</GenerateRequiresPreviewFeaturesAttribute>
    ..
  </PropertyGroup>

I just updated to Visual Studio release v17.4.0 and this bug is affecting all projects as I was running net6.0.

As noted in this thread, <EnablePreviewFeatures> seems only to work with latest version. Since NET 7.0 is released now, updating my framework reference resolved issues. May not be a solution for everyone though.
