Use  lt packages xmlns  urn packages  gt in the place of  lt packages gt

Oh ok - now I get it  You can ignore this one - the XML for this is just not correct - the packages-element is indeed not declared  there is no reference to a schema or whatever   I think this is a known minor bug that won t do a thing because only NuGet will use this   See this similar question also

Change the node to   and create a file  packages xsd  in the same folder  and include it in the project  with the following contents    lt  xml version  1 0  encoding  utf-8    gt   lt xs schema xmlns xs  http   www w3 org 2001 XMLSchema  elementFormDefault  qualified        targetNamespace  urn packages  xmlns  urn packages  gt     lt xs element name  packages  gt       lt xs complexType gt         lt xs sequence gt           lt xs element name  package  maxOccurs  unbounded  gt             lt xs complexType gt               lt xs attribute name  id  type  xs string  use  required    gt               lt xs attribute name  version  type  xs string  use  required    gt               lt xs attribute name  targetFramework  type  xs string  use  optional    gt               lt xs attribute name  allowedVersions  type  xs string  use  optional    gt             lt  xs complexType gt           lt  xs element gt         lt  xs sequence gt       lt  xs complexType gt     lt  xs element gt   lt  xs schema gt

You can also find a copy of the nuspec xsd here as it seems to no longer be available   https   gist github com sharwell 6131243

Taken from this answer    Close your packages config file   Build Warning is gone    This is the first time I see ignoring a problem actually makes it go away        Edit in 2020  if you are viewing this warning  consider upgrading to PackageReference if you can

[xml] The 'packages' element is not declared
