How to add activity source to tracer provider dynamically for a single service?

Question

In the blog here, https://learn.microsoft.com/en-us/dotnet/core/diagnostics/distributed-tracing-instrumentation-walkthroughs , Its mentioned in the best practices for ActivitySource to consider creating a new one for each library rather than using a single source for whole assembly. If we follow this then how do we add these sources while configuring the trace provider. It is not guaranteed that we will have a list of all the source names at the time of configuration. Is there a way of adding these sources at runtime?

Hi @Ravi Patel,

After testing the code in the blog, the source name seems depend on the namespace of your invoked method. So for dynamically get the source name, you can use the code below:

Type myType = typeof(Program);   //The method exists in Program class, get the class type
var source = myType.Namespace;

If there has any problem, please let me know freely.
