Client method name change when using OpenAPI 3 instead of 2

I wanted to use OpenAPI 3 to generate the axios typescript client I use for my project, mainly to use the same enum by reference, rather than having multiple instances being generated (this works fine).

For this, I’ve changed following references. Before:

<PackageReference Include="Swashbuckle.AspNetCore" Version="4.0.1" />
<PackageReference Include="Swashbuckle.AspNetCore.Filters" Version="4.5.5" />

After:

<PackageReference Include="Swashbuckle.AspNetCore" Version="5.0.0-rc4" />
<PackageReference Include="Swashbuckle.AspNetCore.Filters" Version="5.0.0-rc8" />

I use cake for the generation, but the generation is the same when using NswagStudio. With: #addin nuget:?package=Cake.CodeGen.NSwag&version=1.2.0&loaddependencies=true Before:

Task ("Frontend-Generate-API-Client")
    .Does (() => {
        var settings = new TypeScriptClientGeneratorSettings {
        ClassName = "{controller}Client",
        Template = TypeScriptTemplate.Axios,
        OperationNameGenerator = new MultipleClientsFromFirstTagAndOperationIdGenerator (),
        ExceptionClass = "ApiException",
        GenerateDtoTypes = true
        };

        NSwag.FromJsonSpecification (new Uri (localApiUri))
            .GenerateTypeScriptClient (apiClientFilePath, settings);

        Information ($"The client API has been updated in '{apiClientFilePath}'");
    });

After:

Task ("Frontend-Generate-API-Client")
    .Does (() => {
        var settings = new TypeScriptClientGeneratorSettings {
            ClassName = "{controller}Client",
            Template = TypeScriptTemplate.Axios,
            OperationNameGenerator = new MultipleClientsFromFirstTagAndOperationIdGenerator(),
            ExceptionClass = "ApiException",
            GenerateDtoTypes = true,
            CodeGeneratorSettings = {
                SchemaType = NJsonSchema.SchemaType.OpenApi3
            }
        };

        NSwag.FromJsonSpecification (new Uri (localApiUri))
            .GenerateTypeScriptClient (apiClientFilePath, settings);

        Information ($"The client API has been updated in '{apiClientFilePath}'");
    });

Now the method names in the client aren’t being generate as before. Here’s an example: Before: getUserByUserId(id: string): Promise<UserResponseDto> {...} After: users4(id: string): Promise<UserResponseDto> {...}

Here’s the commit including all relevant changes. It can easily be tested and reproduced with it, if needed.

What do I have to change in order to have nice method names again?

I have the same problem. After updating to dotnet core 3 and updating Swashbuckle.AspNetCore the client generated files are different. @taconaut did you find a solution for this?

Are you sure you are still using nswag in the v3 case? Can you also provide the generated specs?
