In NSwag.MSBuild version 14.0.3, the ignoredParameterNames parameter stopped working when creating contracts for records.

for record

public sealed record AppCompatibility(int AppId, int? CompatibleAppid);

I received an expected contract for ts, without equalityContract parameter

export class AppCompatibility implements IAppCompatibility {
    appId!: number;
    compatibleAppid?: number | undefined;

    constructor(data?: IAppCompatibility) {
        if (data) {
            for (var property in data) {
                if (data.hasOwnProperty(property))
                    (<any>this)[property] = (<any>data)[property];
            }
        }
    }

    init(_data?: any) {
        if (_data) {
            this.appId = _data["appId"];
            this.compatibleAppid = _data["compatibleAppid"];
        }
    }

    static fromJS(data: any): AppCompatibility {
        data = typeof data === 'object' ? data : {};
        let result = new AppCompatibility();
        result.init(data);
        return result;
    }

    toJSON(data?: any) {
        data = typeof data === 'object' ? data : {};
        data["appId"] = this.appId;
        data["compatibleAppid"] = this.compatibleAppid;
        return data;
    }

    clone(): AppCompatibility {
        const json = this.toJSON();
        let result = new AppCompatibility();
        result.init(json);
        return result;
    }
}

export interface IAppCompatibility {
    appId: number;
    compatibleAppid?: number | undefined;
}

In the new version 14.0.3, despite the specified excludedParameterNames, I still get equalityContract in the generated contract, why?

export class AppCompatibility implements IAppCompatibility {
    equalityContract!: string;
    appId!: number;
    compatibleAppid?: number | undefined;

    constructor(data?: IAppCompatibility) {
        if (data) {
            for (var property in data) {
                if (data.hasOwnProperty(property))
                    (<any>this)[property] = (<any>data)[property];
            }
        }
    }

    init(_data?: any) {
        if (_data) {
            this.equalityContract = _data["equalityContract"];
            this.appId = _data["appId"];
            this.compatibleAppid = _data["compatibleAppid"];
        }
    }

    static fromJS(data: any): AppCompatibility {
        data = typeof data === 'object' ? data : {};
        let result = new AppCompatibility();
        result.init(data);
        return result;
    }

    toJSON(data?: any) {
        data = typeof data === 'object' ? data : {};
        data["equalityContract"] = this.equalityContract;
        data["appId"] = this.appId;
        data["compatibleAppid"] = this.compatibleAppid;
        return data;
    }

    clone(): AppCompatibility {
        const json = this.toJSON();
        let result = new AppCompatibility();
        result.init(json);
        return result;
    }
}

export interface IAppCompatibility {
    equalityContract: string;
    appId: number;
    compatibleAppid?: number | undefined;
}

Just had this issue. For me it worked with parameter names as those are specified in open API json file. So to exclude something like:

"paths": {
  "/some/path": {
    "post": {
      // ...
      "parameters": [
        { "name": "X-EXCLUDE-ME", "in": "header", ... }
      ]
    }
  }
}

had to specify "X-EXCLUDE-ME" in config instead of generated parameter name (x_EXCLUDE_ME).

P.S. with configuration in .csproj it would look like so:

<ItemGroup>
  <OpenApiReference Include="api.json" CodeGenerator="NSwagCSharp" ClassName="ApiClient">
    <OutputPath>API.g.cs</OutputPath>
    <Options>/JsonLibrary:SystemTextJson /OperationGenerationMode:SingleClientFromPathSegments /ExcludedParameterNames:X-EXCLUDE-ME,X-SOMETHING-ELSE</Options>
  </OpenApiReference>
</ItemGroup>
