I have a .NET6.0 Project which I am trying to publish to Azure Feed using Azure Pipelines.
In the packing step I am having the following Error:

##[error]The nuget command failed with exit code(1) and error(Error NU5128: Some target frameworks declared in the dependencies group of the nuspec and the lib/ref folder do not have exact matches in the other location. Consult the list of actions below:
- Add a dependency group for net6.0 to the nuspec)
##[error]An error occurred while trying to pack the files.

I am not using a custom .nuspec file, it should be properly generated by Azure Pipelines Job.

Here is my .csproj file

 <Project Sdk="Microsoft.NET.Sdk">   
      <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
        <PackageId>PackageId</PackageId>
        <Version>1.0.0</Version>
        <Author>Author</Author>
        <Company>Company</Company>
        <Description>Library defining common objects</Description>
      </PropertyGroup>   
    </Project>

This is my pipeline.yaml file

# Starter pipeline
