Nuget packages are defined in the
.csproj file
So just building the project should download anything necessaryE.g., Dev express supplies NuGets for their UI components only via their private NuGet server.
So, it may happen that the required NuGet packages are not available for you, unless you have a purchased license for said commercial product, or have a trial
Older .NET Framework projects might still use the .nuspec file for specifying NuGet dependencies.
But that doesn't change your steps for restoring and building the solution projects
using helperfunctions. Is this a NuGet method or something else?
Please send the csproj XML content.
In visual studio, double click the project you have issues with to view its definition.
If the project is in the old .NET format (which also means it is in .NET Framework), a configuration window will appear. In this case, it is necessary to first unload the project to view its XML definiton

Just write XML instead of CS, as seen in the example gif
In the solution tree, under the project, do you see any warnings regarding its dependencies? If you expand the project, you'll probably see files within it, along with special items at the top, such as dependencies
Asking all of this, because it is impossible to say from this single line. Apart from a NuGet package reference, it can come from a project reference that is potentially missing from the solution.
Please provide as much $details as possible to receive proper assistance
When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, what you expect the result to be, what .NET version you are using and what platform/environment (if any) are relevant to your question.
