How to add .dcproj into solution via dotnet sdk

[skoruba]

I have a solution named: MyProject.sln and project related to docker called - docker-compose.dcproj.

I want to create dotnet new template which will contain support for docker-compose through project docker-compose.dcproj.

I tried this command:

dotnet sln MyProject.sln add docker-compose.dcproj

I got this error message:

Project 'C:\MyProject\docker-compose.dcproj' has an unknown project type and cannot be added to the solution file. Contact your SDK provider for support.

I am using .net core sdk version 3.1.100.

How to add docker-compose.dcproj into solution via command above?
