You need to do 3 things:
- The summary should be moved from class property to class.
not here
public NameValue FromWarehouse { get; set; }
but to
/// <summary>
/// The warehouse this transfer is coming from
/// </summary>
/// <remarks>GLW, WDI, PSO, SMA, SHW</remarks>
public class NameValue{
....
- You need to add document generation, with Include Xml Comments
services.AddSwaggerGen(c =>
{
var xmlFilename = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
c.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, xmlFilename));
});
- Add this to your .csproj file
<PropertyGroup>
<GenerateDocumentationFile>true</GenerateDocumentationFile>
</PropertyGroup>
This is the example I used
/// <summary>
/// The warehouse this transfer is coming from
/// </summary>
/// <remarks>GLW, WDI, PSO, SMA, SHW</remarks>
public class NameValue
{
/// <summary>
/// The Name
/// </summary>
public string Name { get; set; }
/// <summary>
/// The Value
/// </summary>
public string Value { get; set; }
}
Here is the result:

The remarks, I was not able to include the, but as far as I understand, remarks are used to provide payload example, and it is used on top of the resource method.
All this I use with dotnet 6 and Swashbuckle.AspNetCore Version 6.2.3.
I hope it helps.
