title: Microsoft.Extensioins.Primitive Assembly error
body: <p>I have created a Windows Form Application in .Net 4.8. This project is working ok as stand alone application. I have converted this project to class library to reference into other project. When I create an object and call a method to perform functionaliy, it throws the following error:
  &quot;Could not load file or assembly 'Microsoft.Extensions.Primitives, Version=3.1.0.0, Culture=neutral, PublicKeyToken=abd9793829ddae60' or one of its dependencies. The system cannot find the file specified.&quot;
  I have performed many steps to get rid of it but unfortunately couldn't</p>
  <ol>
  <li>Remove and add reference again.</li>
  <li>Go for the nuget package but cannot do it because of .net framework version.</li>
  <li>Add dependent assembly in .csproj file.
  In main project anyway I can see the added reference but with different version
