You don't need to "restart a project" to target .NET Framework. You just need to use the appropriate TargetFramework element in the csproj file.

Here's an example for a Windows Forms application targeting .NET Framework 4.7.2:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net472</TargetFramework>
    <UseWindowsForms>true</UseWindowsForms>
  </PropertyGroup>
</Project>

If you create a .NET Core 3.1 or .NET 5 project, you can just edit the .csproj file to specify .NET Framework as the target framework - no need to start from scratch.

Well, as your main application is .NET Core, it's running on a core CLR. It cannot be changed to a non-core CLR project. You would need to restart a project if there is no way of achieving the goal you need.

If you also need the .NET Core application for whatever reason, I would recommend using an API call to communicate between the two applications or another method of communication which isn't with the project itself.
