I have a web app solution created on vs code, in which I have 4 project.
One project, named “core.csproj” is targeted framework as: netstandard2.1
All the rest (API.csproj, infrastructure.csproj, emailservice.csproj) are targeted at 3.1 as:
netcoreapp3.1**
Now, I encountered incompatible problem when I tried to add the “core.csproj” as reference project to other projects. Therefore, I wanted to change it. Can anyone please guide how?
The dotnet command I used to add reference project:
dotnet add Core/Core.csproj reference API/API.csproj
The Error I got:
API.csproj cannot be added due to incompatible targeted frameworks between the two projects. Review the project you are trying to add and verify that is compatible with the following targets: – unsupported.

Method 1
Edit the core.csproj file and change the TargetFramework property to 3.1. and save the file.
Rebuild the solution, if any errors result correct them.
Rebuild again.
Please take a backup of the project before you do change for any unexpected problem risk.
