I have to add/update some data in a database when specific events are emitted by a solidity smart contract. When using web3.js there is a simple method called watch(), but I didn't find anything like that in the Nethereum C# library.

There is an example in web3.js:

var instructorEvent = Coursetro.Instructor();
instructorEvent.watch(function(error, result){

Another way to do it using web3.js:

    .on('data', async function(event){
        // Do something here
    .on('error', console.error);

It hasn't to be a solution with Nethereum but has to work on C#. In case I don't discover an answer to C#, I will try it using a Node.JS API.

You can use streaming websocket client. It is present in the docs - https://docs.nethereum.com/en/latest/introduction/ws/
