Install and set up the MGCB Editor. If you have dotnet installed:

MGCB Editor is no longer a .NET global tool, and doesn't need to be installed or registered.

However, if you are migrating from 3.8.0, you will need to setup a configuration file. Next to your .csproj, create a folder nammed .config and a file within it nammed dotnet-tools.json with this content:

{
  "version": 1,
  "isRoot": true,
  "tools": {
    "dotnet-mgcb": {
      "version": "3.8.1.263",
      "commands": ["mgcb"]
    },
    "dotnet-mgcb-editor": {
      "version": "3.8.1.263",
      "commands": ["mgcb-editor"]
    },
    "dotnet-mgcb-editor-linux": {
      "version": "3.8.1.263",
      "commands": ["mgcb-editor-linux"]
    },
    "dotnet-mgcb-editor-windows": {
      "version": "3.8.1.263",
      "commands": ["mgcb-editor-windows"]
    },
    "dotnet-mgcb-editor-mac": {
      "version": "3.8.1.263",
      "commands": ["mgcb-editor-mac"]
    }
  }
}

Please note that you can't use the 3.8.1.* wildcard in the dotnet-tools.json file (tool versions have to be fully qualified). We strongly recommand that the versions match the MonoGame version referenced in your .csproj (if you're using the * wildcard, make sure that they don't end up mismatching if the nugets are updated without you noticing).

You will also need to add this to your .csproj:

<Target Name="RestoreDotnetTools" BeforeTargets="Restore">
  <Message Text="Restoring dotnet tools" Importance="High" />
  <Exec Command="dotnet tool restore" />
</Target>

If you need old global version of MGCB editor

dotnet tool install --global dotnet-mgcb-editor
mgcb-editor --register

Note: If you are using the older versions of the editor, then you need to update its path in the project's setting accordingly.
