body: <p>I have a ASP.NET Core 2.1 and added a nuget package of  Microsoft.WindowsAzure.Storage , But after pushing the code to repo, the build pipeline occurs package error while running the build agent and is it necessary to add any other agents in build pipeline other than  BUILD, RESTORE, TEST and PUBLISH.</p>
  <h2>[error]Error: The process 'C:\hostedtoolcache\windows\dotnet\dotnet.exe' failed with exit code 1</h2>
  <p>Info: Azure Pipelines hosted agents have been updated to contain .Net Core 3.x SDK/Runtime along with 2.2 &amp; 2.1. Unless you have locked down a SDK version for your project(s), 3.x SDK might be picked up which might have breaking behavior as compared to previous versions.</p>
