Synchronizing access to a pool of resources

• ASP.NET Core

  ASP.NET Core is a cross-platform .NET framework for building modern cloud-based web applications on Windows, Mac, or Linux.

  

I have a Web API method (asp.net core 5) which will typically take a second or two to execute, most of that time is spent awaiting various IO-bound tasks. The method takes an ID as a parameter, which is used to lookup a record in a database table, make calls to other services and update the record - it is imperative that two concurrent requests do not operate on the same record otherwise race condition and corrupt data.

  Let's learn devops by shipping a final product in .NET 5

One example here https://github.com/EliotJones/LetsShip/blob/main/src/PriceFalcon.JobRunner/Worker.cs#L111 where I have several agent applications each of which may start up to 5 jobs, a job can take a couple of minutes to execute and while running the same request twice isn't the end of the world I'd prefer to avoid it. I use FOR UPDATE when selecting to take an update lock on the row in postgres (similar functionality hopefully exists for your DB).
