Building and managing C# function dependencies
Cloud Functions supports two ways to manage dependencies for a C# function: automatic installation using nuget and manual delivery of dependencies with the source code.
NuGet
NuGet is a package management system for .net.
To install dependencies using nuget, add a link to the required package to the *.csproj project file. No other actions are required. You can do this using the .NET Core CLI.
Manual delivery of dependencies
To configure dependencies manually, place the compiled project with all dependencies in the project archive root.
You can do this using the .NET Core CLI publish command
This does not require you to add the source code or project files to the archive.
The process of installing dependencies has resource and execution time limits. For more information, see Quotas and limits in Cloud Functions. You can view the dependency installation log using the link that appears in the list of operations.
