How to set applicationname in c# open telemetry app for tanzuobservabilityexporter

[syamalaids]

Hello,
The "ReadMe" for tanzuobservabilityexporter states the following:
*Application identity tags, which are required by Tanzu Observability, are added if they are missing.
application is set to "defaultApp".
service is set to "defaultService".

I am using the following method which is setting the service name:

   TracerProvider tracerProvider = Sdk.CreateTracerProviderBuilder()
                                    .AddSource(ServiceName)
                                    .SetResourceBuilder(
                                            ResourceBuilder.CreateDefault()
                                                .AddService(serviceName: ServiceName, serviceVersion: ServiceVersion))
                                    .AddHttpClientInstrumentation(SetInstrumentationOptions)
                                    .AddOtlpExporter(SetExporterOptions)
                                    .Build();

Have no clue how to set the "Application Name"? Wavefront defines "ApplicationTags" but that will work with their SDK.
How to achieve the same with OpenTelemetry?

Hi @syamalaids, take a look at our C# example code for setting the application name via OTel Resource attributes: https://github.com/wavefrontHQ/opentelemetry-examples/blob/master/DOTNET-example/Web-App/Program.cs#L8-L10. On line 17, we add those attributes to the ResourceBuilder.
