To use it:\n\n1. Install the [.NET SDK](https://dotnet.microsoft.com/download).\n\n2. Install the template package:\n\n dotnet new install Google.Cloud.Functions.Templates\n\n| **Note:** versions of the .NET SDK earlier than .NET 7 use `dotnet new -i` instead of `dotnet new install`.\n\nTemplates are provided for the three kinds of functions in C# (the default), F#,\nand Visual Basic. When creating a new project from a template, specify\n`-lang f#` to create an F# project, or `-lang vb` to create a Visual Basic\nproject. For more information, see:\n\n- [.NET Languages](/functions/1stgendocs/concepts/dotnet-langs) (for F# and Visual Basic)\n\nSelect a .NET Functions Framework version\n-----------------------------------------\n\nDifferent versions of the .NET Functions Framework support different runtimes.\nVersion 1 supports .NET Core 3.1 and later, with templates defaulting to\n.NET Core 3.1. Version 2 supports .NET 6 and later, with templates defaulting\nto .NET 6.\n\nTo upgrade an existing project using .NET Functions Framework version 1,\nedit the project file (or use Visual Studio) to update all dependencies that\nbegin with `Google.Cloud.Functions` to the latest version, and set the\ntarget framework to .NET 6.\n\nSelect your runtime\n-------------------\n\nCloud Run functions supports several versions of .NET, listed on the\n[Runtime support](/functions/1stgendocs/runtime-support#.net-core) page. When you deploy\nyour function, you must specify\na .NET runtime corresponding to the target framework in your project file\n(`MyFunction.csproj` or similar). To specify your .NET runtime: \n\n### gcloud\n\nIf you're using the Google Cloud CLI, specify the runtime\nby using the `--runtime` parameter. The `--entry-point` flag specifies the\nfully qualified class name (FQN). For example: \n\n```bash\ngcloud functions deploy NAME --no-gen2 --entry-point FQN --no-gen2 --runtime dotnet6 --trigger-http\n```\n\nFor more deployment parameters, see\n[Deploy a Cloud Run function](/functions/1stgendocs/deploy#basics).\n\n### Console\n\nIf you're using the Google Cloud console, see the [Google Cloud console\nquickstart](/functions/1stgendocs/console-quickstart-1st-gen) for\ndetailed instructions.\n\nFunction preparation\n--------------------\n\nYou can prepare a function directly from the Google Cloud console or write it on\nyour local machine and upload it. To prepare your local machine for .NET\ndevelopment, see [Setting up a .NET development\nenvironment](/dotnet/docs/setup).\n\nThe library that invokes your function is the\n[.NET Functions Framework](/functions/1stgendocs/functions-framework).\n| **Note:** The only type of [event-driven functions](/functions/1stgendocs/writing#types_of_cloud_functions) .NET supports are [CloudEvent functions](/functions/1stgendocs/writing#cloudevent_functions).\n\nSource code structure\n---------------------\n\nIn order for Cloud Run functions to find your function's definition, each\nruntime has certain structuring requirements for your source code. See [Write\nCloud Run functions](/functions/1stgendocs/writing#functions-writing-file-structuring-csharp)\nfor more information.\n\nSpecifying dependencies\n-----------------------\n\nYou can specify dependencies for your function by adding them to a project file.\nFor more information, see [Specifying dependencies in\n.NET](/functions/1stgendocs/writing/specifying-dependencies-dotnet).\n\nWhat's next\n-----------\n\n- [Learn about the other .NET languages](/functions/1stgendocs/concepts/dotnet-langs) you can use to write Cloud Run functions: F# and Visual Basic."]]
