Install-Package Swashbuckle.AutoRestExtensions

Starting version 5.6.0, version of this package will follow SwachBuckle version

Install Autorest

	npm install -g autorest

GlobalConfiguration.Configuration
	.EnableSwagger(
		c =>
		{
			c.SingleApiVersion("v1", "Web Api");
			c.ApplyAutoRestFilters(
				new SwaggerDocsConfigExtensionsConfiguration()
				{
					ApplyEnumTypeSchemaFilter = true,
					ApplyNullableTypeSchemaFilter = true,
					ApplyNonNullableAsRequiredSchemaFilter = true
				},
				null);
			c.DescribeAllEnumsAsStrings(true);
		})
	.EnableSwaggerUi();

This Filter will apply the x-nullable attributes in the generated JSON, x-nullable is handled poorly in V 0.17.3 of Autorest so this is why I recommend using nightly. If you don't want to use nightly build you may end up having your complex property like SomeDto.List<Guid> generated as SomeDto.List<Guid?>. See Azure/autorest#1578 for more information about Enumerable being generated with nullable properties.

This looks at the schema for the x-nullable property and if the property is marked as x-nullable = false, it add the property in the required array which will be validation against null when generated back to C#.

1. Compile the code with Visual Studio 2017

1. Run the following command in VS console

Nuget Pack .\Swashbuckle.AutoRestExtensions\Swashbuckle.AutoRestExtensions.csproj -IncludeReferencedProjects
