NuGet Error NU5005

Ensure 'F:\project\project.nuspec' includes source and symbol files. For help on building symbols package, visit https://docs.nuget.org/.

Issue

The NuGet pack operation was invoked with the -Symbols option, but the nuspec file does not contain any source or symbols files.

Solution

When building a symbols package, ensure that the folder containing the nuspec file contains assembly files for which the symbols need to be packaged.
