Help Building a SOAP API

Hello All, I need some help finding a good example or resource to learn to build a SOAP API. I feel like I'm in a unique situation with this. I currently have a console app that runs as a windows service that generates data when it receives a message every three seconds from a message queue.

 

after it receives the message it stores the data in local values until the next time it receives data. I need a client software to be able to connect to my and pass it a value and if the value matches a parameter of the generated data then that data needs to be returned to the client.

Would anyone be able to point me in the right direction to learn how to do this or have any idea's of a good way to proceeds?

 

I tend to learn best by example so if you know of any GitHub examples of something similar or examples somewhere on the web that would be amazing!

 

Thanks for the help all!
