This environment is identified\nby the language version, and is known as the runtime ID.\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 [Set up a .NET development environment](/dotnet/docs/setup).\n\nSupported .NET runtimes and base images\n---------------------------------------\n\nTemplate package\n----------------\n\nThe template package helps you to create new functions. 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.\n\nSelect your runtime\n-------------------\n\nWhen you deploy your function, you must specify a .NET runtime\ncorresponding to the target framework in your project file\n(`MyFunction.csproj` or similar). You can select one of the\n[supported](#supported-runtimes) .NET runtimes for your function during deployment.\n\nYou can select a runtime version using the Google Cloud console, or the\ngcloud CLI. Click the tab for instructions on using the tool of\nyour choice: \n\n### gcloud\n\nSpecify the [.NET base image](/run/docs/configuring/services/runtime-base-images#how_to_obtain_base_images) for your function using the `--base-image` flag,\nwhile deploying your function. For example: \n\n gcloud run deploy \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e \\\n --source . \\\n --function \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e \\\n --base-image dotnet8\n\nReplace:\n\n- \u003cvar translate=\"no\"\u003eFUNCTION\u003c/var\u003e with the name of the function you are\n deploying. You can omit this parameter entirely,\n but you will be prompted for the name if you omit it.\n\n- \u003cvar translate=\"no\"\u003eFUNCTION_ENTRYPOINT\u003c/var\u003e with the entry point to your function in\n your source code. This is the code Cloud Run executes when your\n function runs. The value of this flag must be a function name or\n fully-qualified class name that exists in your source code.\n\nFor detailed instructions on deploying a function using the gcloud CLI, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#gcloud).\n\n### Console\n\nYou can select a runtime version when you create or update a Cloud Run function in the Google Cloud console. For detailed\ninstructions on deploying a function, see [Deploy functions in Cloud Run](/run/docs/deploy-functions#deploy-functions).\n\nTo select a runtime in the Google Cloud console when you create a function, follow these steps:\n\n1. In the Google Cloud console, go to the Cloud Run page:\n\n [Go to Cloud Run](https://console.cloud.google.com/run)\n2. Click **Write a function**.\n\n3. In the **Runtime** list, select a .NET runtime version.\n\n4. Click **Create**, and wait for Cloud Run to create the service\n using a placeholder revision.\n\n5. The console will redirect you to the **Source**\n tab where you can see the source code of your function. Click **Save and redeploy**.\n\nFor detailed instructions on updating the runtime version after your function is\ndeployed, see\n[Re-deploy new source code](/run/docs/deploy-functions#update-code-functions).\n\nSource code structure\n---------------------\n\nFor Cloud Run functions to find your function's definition, your\nsource code must follow a specific structure. See\n[Write Cloud Run functions](/run/docs/write-functions#.net) for\nmore information.\n\nSpecifying dependencies\n-----------------------\n\n.NET Cloud Run functions uses\n[Microsoft Build Engine (MSBuild) project files](https://docs.microsoft.com/en-us/aspnet/web-forms/overview/deployment/web-deployment-in-the-enterprise/understanding-the-project-file)\nwhich are central to the build and deployment process. You can specify\ndependencies for your function in a project file. For C# the file extension is\n`.csproj`, for F# it is `.fsproj`, and for Visual Basic it is `.vbproj`.\n\nFor more discussion of dependencies and other types of customization,\nsee [Customization through Functions Startup classes](https://github.com/GoogleCloudPlatform/functions-framework-dotnet/blob/master/docs/customization.md#customization-through-functions-startup-classes)."]]
