Defining NuGet restore sources in the csproj

If you use an internal NuGet server or want to be explicit about which sources to use for package restore, you need to configure them in NuGet. You can use the dotnet nuget command to manage sources:

dotnet nuget add source https://api.nuget.org/v3/index.json --name nuget.org
dotnet nuget add source https://azureartifacts.microsoft.com/myTeam --name myTeam --username user --password pass

However, this requires every developer to configure the sources on their machine, and you also need to set them up on the CI machine.

Instead, you can set the configuration for your project directly in the csproj file using the <RestoreSources> or <RestoreAdditionalProjectSources> element.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RestoreAdditionalProjectSources>
      https://api.nuget.org/v3/index.json;
      https://www.myget.org/F/sixlabors/api/v3/index.json;
      $(MSBuildThisFileDirectory)/../References/
    </RestoreAdditionalProjectSources>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="SixLabors.ImageSharp" Version="1.0.0-unstable1129" />
    <PackageReference Include="MyLocalPackage" Version="1.0.0" />
  </ItemGroup>

</Project>

If you need a more advanced NuGet configuration or use dotnet tool, you still need to use a nuget.config file in your repository.
