I would like to upgrade .NET framework 4.7.2 to .NET 5. I have good number of libraries for my project. For scenario I have 50 libraries. 35 are legacy libraries and less maintenance involved. 15 libraries are active. So, my plan is to port to .NET 5 for only active libraries. Can I only port the 15 libraries and retain remaining 35 libraries are in .NET framework.

Can you please guide me Is this approach is feasible?

    Hi @James J ,

    Thank you for reporting it in Microsoft Q&A.

    For your requirement, please try the following code in .csproj file to port to .NET 5.0:

    <?xml version="1.0" encoding="utf-8"?>  
    <Project Sdk="Microsoft.NET.Sdk">  
     <PropertyGroup>  
     <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>  
     <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform>  
     <ProjectGuid>{5623B94B-4831-4479-9F46-CE995E022094}</ProjectGuid>  
     <OutputType>Exe</OutputType>  
     <RootNamespace>ConsoleApp9</RootNamespace>  
     <AssemblyName>ConsoleApp9</AssemblyName>  
     <TargetFramework>net5.0</TargetFramework>  
     <FileAlignment>512</FileAlignment>  
     <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>  
     <Deterministic>true</Deterministic>  
     <GenerateAssemblyInfo>false</GenerateAssemblyInfo>  
     </PropertyGroup>  
    </Project>  
    

    For more details, you can also refer to the document: Example of migrating to .NET Core 3.1.

    Sincerely,
    Anna
