When a Visual Studio solution (.sln) contains several projects, it helps to have Jenkins build each project on its own. This PowerShell build script builds a single .NET project (.csproj) within a solution: it restores, cleans, builds and publishes the project, then creates a .nuspec and packs it into a NuGet package with nuget.exe.

Like my Jenkins NuGet package build script, it reads the Jenkins WORKSPACE and JOB_NAME environment variables plus VERSION and SLN_NAME job parameters, so the Jenkins job name should match the project name. Replace the NuGet path, server URL and API key placeholders with your own.
