Create nuget package for a solution with multiple projects

There is a planned feature targeting this exact scenario.

This is how it will apparently look like:

> nuget.exe pack proj.csproj -IncludeReferencedProjects

It has apparently been implemented mere days ago, but there are bugs still being ironed out.

The feature, as it currently stands, allows:

• packaging several projects' artifacts into a single nuget package (by walking project references recursively),

OR

• creating nuget package references to those projects's associated packages, if the referenced projects have accompanying .nuspec files.

The feature request dates back all the way to 1.5, but it kept slipping. Recently though, it gathered enough mass (requests) to be scheduled for release in Nuget 2.3.

The release plan pegs version 2.3 for "End of April, 2013" so stay tuned.
(Presently, the latest Nuget version is 2.2.1).

I think Charles means he wants NuGet to automatically resolve project references into package dependencies if said referenced projects also are used to construct NuGet packages, right?

Example:

1. Logging is set up to generate a NuGet package
2. Logging.Nlog is set up to generate a NuGet package
3. Logging.Nlog has a project reference to Logging.
4. The generated Logging.Nlog package should get a dependency on the generated Logging package.

This is something I had been looking for myself as well, but sadly I found that it is currently not supported. There is a work item on it, scheduled for NuGet 1.7, but there isn't even a design on how to handle this yet.

There is currently no way to do exactly what you ask, but the following will help you streamline your updates.

It sounds like you need to add nuspec files to your solution. Something like the following three files. Note the dependencies in the second two. These refer to the same dll version as common through [$version$]. This means that when you run the following command, it updates all three because the square brackets on the dependencies require a specific version of the dependent packages.

PM> update-package common

In Hudson, you will need to execute these nuspec files using nuget pack command (see Nuget command reference) and include the resulting packages in your artifacts, AND deploy them to your local nuget server. I will leave that over to you.

The other thing you would need to do is ensure that all of your assemblies get the same version for the same build. Again, Hudson can take care of this or you could use a common AssemblyInfo file.
