Is it possible to consume bicep files in C# projects?

[hxd1478]

Looking to do some buildout automation where we can parse/consume bicep files so that we can get the values off of a bicep object. Then, do some additional operations on them before deploying them. Is this possible? Somehow to consume the bicep objects in either dotnet or C# projects or in F#?

You could look at how the Bicep PowerShell module does it by rebuilding parts of the bicep project and including it. Might even be able to use the BicepNet module as it already does some magic with outputting objects I believe.

We do have a NuGet package that is used by the CLI and language server to parse Bicep files: https://www.nuget.org/packages/Azure.Bicep.Core. It's not very well documented, but there are many examples of tests in this repo invoking code in that assembly.

for Azure.Bicep.Core 0.26.54:

	var host = Host.CreateDefaultBuilder().ConfigureServices(services => 
	{
		services.AddSingleton<IFileSystem, FileSystem>();
		services.AddSingleton<INamespaceProvider, DefaultNamespaceProvider>();
		services.AddSingleton<IResourceTypeProviderFactory, ResourceTypeProviderFactory>();
		services.AddSingleton<IContainerRegistryClientFactory, ContainerRegistryClientFactory>();
		services.AddSingleton<ITemplateSpecRepositoryFactory, TemplateSpecRepositoryFactory>();
		services.AddSingleton<IModuleDispatcher, ModuleDispatcher>();
		services.AddSingleton<IArtifactRegistryProvider, DefaultArtifactRegistryProvider>();
		services.AddSingleton<ITokenCredentialFactory, TokenCredentialFactory>();
		services.AddSingleton<IFileResolver, FileResolver>();
		services.AddSingleton<IEnvironment, Environment>();
		services.AddSingleton<IConfigurationManager, ConfigurationManager>();
		services.AddSingleton<IBicepAnalyzer, LinterAnalyzer>();
		services.AddSingleton<IFeatureProviderFactory, FeatureProviderFactory>();
		services.AddSingleton<ILinterRulesProvider, LinterRulesProvider>();
		services.AddSingleton<BicepCompiler>();
	}).Build();
		
	var bicepCompiler = host.Services.GetRequiredService<BicepCompiler>();
	var compilation = bicepCompiler.CreateCompilationWithoutRestore(new Uri("path-to-bicep-file", UriKind.Absolute));
	Console.WriteLine(compilation.Emitter.Template().Template);

do you know how to pass dynamic bicep parameters to the bicep in c#?

[GABRIELNGBTUC]

Template compilation does not require parameters as all it does is convert bicep syntax into an ARM file.

That's more something that would be done by creating an ARM deployment with the Azure SDK
