I consider it generally good practice to include the XML documentation file generated by the C# build in NuGet packages alongside the DLLs to provide intellisense documentation
As long as you set GenerateDocumentationFile
in your csproj file like this:
netstandard2.0
true
then all the defaults will generate the documentation file at the correct location and it will be included in the NuGet package.
If Visual Studio added DocumentationFile
or other elements, you can delete them and replace it with the single GenerateDocumentationFile
property.
