Asynchronous windows services

Calling async methods from a Windows Service Ask Question. Asked 8 years, 1 month ago. Active 7 years ago. Viewed 23k times. A couple thoughts come to mind: Am I well covered as far as unobserved exceptions by placing that handler in Main? Would there be any benefit to using Task. Run, something like Task. Wait ;? ConfigureAwait false here?

I'm doubting it since there's no await here. I haven't seen any examples of using this, and since I'm starting an infinite loop I don't know that syncing back up to some context is even relevant here.

I actually just saw your comment on CodePlex from forever ago, which for some reason I was not notified of It's not clear to me whether it should be called from OnStart or from Main.

N1njaB0b: Yeah, I never did get around to writing that up You should call it from OnStart and then join to it in OnStop. This uses the duplex message exchange pattern with one-way messages. In this case, the service contract specifies a one-way message exchange that either side can implement as asynchronous calls or implementations, or not, as appropriate. Generally, when the contract is an exchange of one-way messages, the implementations can largely be asynchronous because once a message is sent the application does not wait for a reply and can continue doing other work.

The design guidelines for the event-based asynchronous model state that if more than one value is returned, one value is returned as the Result property and the others are returned as properties on the EventArgs object. One result of this is that if a client imports metadata using the event-based asynchronous command options and the operation returns more than one value, the default EventArgs object returns one value as the Result property and the remainder are properties of the EventArgs object.

This generates a signature that returns the response message as the Result property on the EventArgs object. All internal return values are then properties of the response message object.

The RESTHandler that handles our request when we execute a client call to a web service method we've tagged as a ScriptMethod is synchronous.

I've gotten different responses from MSFT regarding why this is the case, but it seems that the consensus was that since the next version of ASP. Then why wasn't WCF supported to begin with? My understanding from the document I referenced in the first post of this thread was that asynchronous web methods are basically a server-side construct that provides a framework within which you can return a thread to the pool until some long-running process completes.

In fact, if you look at the WSDL created for the web service described in that document or point your browser at webservice. That's absolutely correct. Since ASP. I have the exact same issue. We are making a call to a web service that in some cases has to start a process that can take a few seconds to complete.

With the high volume we are handling keeping that ASP. Net thread locked is not an option so we moved to an Async Web Method model. The problem is that everything works perfectly find when you use XML as the return type, as soon as you move to the JSON serialization you get a method not found when you look for MethodName. I know this post is an year old. Has this been resolved? I am trying to call an asynchronous web service from javascript.

I have a asp. Throw New soapException "An Error occurred while processing output information. Please keep on reading. WMI, also known as Windows Management Instrumentation, is a set of extensions to the Windows Driver Model that works together to support the infrastructure for managing data and operations on Windows-based operating systems.

It allows software developers to write scripts and programs to manage and query devices, user accounts, windows services, and other internal aspects of the OS. It is important for the Windows systems. As mentioned before, the genuine unsecapp. However, a virus could be named as unsecapp. In this case, unsecapp. How to identify if the unsecapp. Well, you can check its file location.
