title: How to upgrade WASM app to NET5 framework?
body: <p>I've decided to upgrade one of my projects to the latest .NET version (.NET 5).</p>
  <p>It consists of one asp.net core app (web api) targeting netcoreapp3.1 and a blazor WASM project targeting netstandard2.1.
  after updating targetframework to net5.0 in both projects, api project is working fine but not the WASM project.</p>
  <p>what are the steps that I should follow for upgrading?</p>
  <p>p.s. I have latest visual studio (Version 16.8.1) and dotnet (version 5.0.100)</p>
  <p>The error message in Blazor app:</p>
  <blockquote>
  <p>HTTP Error 500.33 - ANCM Request Handler Load Failure<br>
