Guidance for creating packages with more than one PackageType?

[brandom-msft]

In our current setup, we publish our project as a "dotnet tool". Recently we've had a customer ask that we publish it as a "Dependency" as well, so they can take a standard dependency on it in their project setup.

The NuGet docs specify that one or more types are supported so I updated our package, but now installation via dotnet tool fails.

Error output:

/tmp/3x3ko4cy.ns2/restore.csproj : error NU1102: Unable to find package Microsoft.CognitiveServices.Speech with version (= <version.num>)
/tmp/3x3ko4cy.ns2/restore.csproj : error NU1102:   - Found 32 version(s) in nuget.org [ Nearest version: 1.22.0 ]
/tmp/3x3ko4cy.ns2/restore.csproj : error NU1102:   - Found 0 version(s) in /mnt/vss/_work/1/s
The tool package could not be restored.

Tool 'microsoft.cognitiveservices.speech.cli' failed to install. This failure may have been caused by:
     * You are attempting to install a preview release and did not use the --version option to specify the version.
     * A package by this name was found, but it was not a .NET tool.
     * The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
     * You mistyped the name of the tool

This issue from a few years back mentions that multiple package types are intentionally disallowed for packages of type DotnetTool.

Is this still the case? If so, can you share any guidance/documentation for how to best provide multiple package types for a given project?
