Two steps that i needed for this in .NET 6.
Add this to program.cs file;
// Register swagger generator, you can define multiple documents here
services.AddSwaggerGen(s =>
{
s.SwaggerDoc("v1", new OpenApiInfo
{
Title = "FOO API",
Version = "v1"
});
var xmlFile = $"{typeof(Presentation.AssemblyReference).Assembly.GetName().Name}.xml";
var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
s.IncludeXmlComments(xmlPath);
});
Edit project .csproj file and add / change these nodes:
<PropertyGroup>
<!--
Make sure documentation XML is also included when publishing (not only when testing)
see https://github.com/Azure/service-fabric-issues/issues/190
-->
<GenerateDocumentationFile>true</GenerateDocumentationFile>
</PropertyGroup>
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Debug|AnyCPU'">
<DocumentationFile>bin\$(Configuration)\$(AssemblyName).xml</DocumentationFile>
</PropertyGroup>
This also works with .NET Core 3.1. more info can be found here.
