title: How to build Visual Studio solution with .NET Framework and .NET Standard projects?
body: <p>I have a solution containing .NET Framework project - WPF application, frontend - and multiple .NET Standard projects - backend. I need to build the .NET Framework project, but to do it, I must build the .NET Standard projects, because the .NET Framework project references the .NET Standard projects.</p>
  
  <p>Visual Studio Build and MSBuild throw errors like "'System' namespace doesn't exist" in the .NET Standard projects.</p>
  
  <p>Net Core build fails to find some assemblies in certain Nuget packages, namely Prism and DevExpress.</p>
  
  <p>How should I build .NET Framework WPF app that is referencing .NET Standard in Azure DevOps?</p>
