Cannot use "useHttpAttributeNameAsOperationId" after migration to NSwag 14

[alex1ozr]

Hello!
I'm currently updating my project to .NET 8 with the latest version of NSwag (14.0.0). I am encountering an issue with configuring documentGenerator/aspNetCoreToOpenApi section in nswag.json.
I cannot set "useHttpAttributeNameAsOperationId": true.

I have ASP.NET API (.NET 8) with controller methods like this:

[ProducesResponseType(typeof(PersonResponse), StatusCodes.Status201Created)]
[ProducesResponseType(typeof(ValidationProblemDetails), StatusCodes.Status400BadRequest)]
[ProducesResponseType(typeof(ProblemDetails), StatusCodes.Status409Conflict)]
[HttpPost("{id:guid}", Name = "CreatePerson")]
public async Task<IActionResult> Create([FromRoute] Guid id, [FromBody] PersonRequest request)
{ 
//...
 }

I also have ClientGenerator project with the following .csproj:

<Project Sdk="Microsoft.NET.Sdk">
    
    <PropertyGroup>
        <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
    </PropertyGroup>
    
    <Target Name="NSwag" AfterTargets="AfterBuild" Condition=" '$(Configuration)' == 'Debug' ">
        <Exec Command="$(NSwagExe_Net80) run nswag.json /variables:Configuration=$(Configuration)" 
              EnvironmentVariables="SkipMigration=True"
              ConsoleToMSBuild="true" />
    </Target>
    
    <ItemGroup>
        <PackageReference Include="NSwag.MSBuild" >
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
        </PackageReference>
    </ItemGroup>
    
    <ItemGroup>
      <ProjectReference Include="..\Api\Api.csproj" />
    </ItemGroup>

    <ItemGroup>
        <None Include="nswag.json" />
    </ItemGroup>
    
</Project>

Here is an example of my nswag.json:

{
  "runtime": "Net80",
  "defaultVariables": null,
  "documentGenerator": {
    "aspNetCoreToOpenApi": {
      "project": "../Api/Api.csproj",
      "documentName": "v1",
      "msBuildProjectExtensionsPath": null,
      "configuration": null,
      "runtime": null,
      "targetFramework": null,
      "noBuild": true,
      "msBuildOutputPath": null,
      "useHttpAttributeNameAsOperationId": true,
      "verbose": true,
      "workingDirectory": null,
      "aspNetCoreEnvironment": null,
      "output": "../Client/swagger.json",
      "newLineBehavior": "Auto"
    }
  },
  "codeGenerators": {
    //...
    }
  }
}

My goal is to get a generated client with the method CreatePerson instead of NSwag's default Person_Create.
Everything was fine till .NET 8...

Now, every time I build a ClientGenerator project it automatically rewrites nswag.json and deletes many (written by me) settings from there.

Okay, I tried different nswag.json samples from this repo by adding useHttpAttributeNameAsOperationId:

• A big one wasn't overridden by NSWag
• A small one was overridden by NSwag

In both cases, there was no success and I still got method names like {controllerName}_{controllerMethodName} instead of the expected ones.

Is this behaviour expected or is it a bug?
What's happened with useHttpAttributeNameAsOperationId setting in 14.0.0?

Thank you in advance for your help.

This occurs as I guess there is no property in command anymore.
https://github.com/RicoSuter/NSwag/blob/master/src/NSwag.Commands/Commands/Generation/AspNetCore/AspNetCoreToOpenApiCommand.cs

SImilar to eq. ApiGroupNames - you can define it in your code

 services.AddOpenApiDocument(document =>
 {
     document.UseHttpAttributeNameAsOperationId = true;
 });
