I have uploaded my WebAPI site to a staging server and when the application attempts to send an email via MvcMailer I receive an SmtpException, but the email does get sent, exactly as required to the correct recipient!
Very odd behaviour. Surely the email shouldn't send when a send exception is produced?
It is a new windows server 2012 build too and this is the first site, so it could be something else I've forgotten to do.
Anyone got any ideas what could be causing this behaviour?
Here are the config settings:
<system.net>
<mailSettings>
<smtp from="no-reply#mysite.com">
<network host="127.0.0.1" port="25" />
</smtp>
</mailSettings>
</system.net>
Here is the error:

The inner exception is "The remote host closed the connection. The error code is 0x80070057."
They only happen in the product environment, it's not my code, so try catch can not help.
The UncaughtExceptionHandlers also can not catch it:
UncaughtExceptionHandlers.Add((req, res, operationName, ex) => {
if (ex is HttpException && ex.Message.StartsWith("The remote host closed the connection", StringComparison.InvariantCultureIgnoreCase)) {
res.EndRequest(true);
}
});

It happens too many times, so I want to ignore it.
How could do the trick with the internal async exception process?
You would need to filter out the error messages from ServiceStack.HttpResponseExtensionsInternal Type in your current logger implementation.

All projects in the solution are build under framework 4.8
All have Any Cpu as Platform Target.
Not as 32-bit prefer option active.
I have x64 arquitecture selected for tests.
There is no testFile settings in use.
I try rebuild, clean rebuild, resinstall VS, nothing work. I can't find out what this error is.
I had a similar issue workaround try this command in the in run window "devenv /ResetSettings", It worked for me.
Microsoft recognized the problem and roll out a fix in version VS 2019 16.5.2.
It is available now as VS 2019 16.5.2 Preview 2
I had this issue in Visual Studio Enterprise 2019 Version 16.5.4, but restarting VS fixed it.
Faced this issue in following version. Clean and Rebuild Solution worked for me.
Microsoft Visual Studio Community 2019
Version 16.6.3
Fixed by closing and opening VS.
Everything worked (VS2019) and suddenly started failing with a similar (did not compare word to word) callstack.
Rebuilding did not help, neither did manually killing hung processes from test console.
After re-opening VS - everything back to normal
I had the same problem when running Visual Studio 2019
You can type this statement in the run window
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\devenv.exe /NoSplash /ResetSettings General /Command Exit"
Note, first enter the address of the executable file of the desired version
It is going to be alright

How can I handle and ignore these exceptions by exception filter? Why this error occurs and how can I reproduce that? I wanna catch and ignore only The client disconnected but not all HttpException
I saw this similar question but how can I do that in exception filter?
You can ignore these exceptions.
The exception says what the problem is: "The client disconnected". It means that the client initiated a request but then disconnected before it bothered to read all of the response.
There are any numbers of reasons why that might be the case, but (unless you have a dodgy internet connection at your server end) it is almost certainly an issue at the client end. I regularly see these myself and mostly it seems to be related to a bot. So I filter them out and ignore them.
try
{
// Open Connection
// Do stuff
}
catch (HttpException ex)
{
// Log it?
// Ignore it?
// Do what you want with it?
}
finally
{
// Close connection
}
I have implemented an Azure Batch example using a template based on the following sample:
https://github.com/Azure/azure-batch-samples/tree/master/CSharp/TextSearch
My solution creates a Job Manager task, which in turn creates multiple child tasks for each of my divisions. I am receiving a "BadRequest" error when I call batchClient.JobOperations.AddTaskAsync in the code below:
Console.WriteLine("Submitting {0} mapper tasks.", extracts.Count());
//The collection of tasks to add to the Batch Service.
List<CloudTask> tasksToAdd = new List<CloudTask>();
// Create Batch jobs
foreach (var extract in extracts)
{
// ToDo: Uncomment this
// extractService.SetStatus(extract.Id, WarehouseMasterConstants.eExtractStatus.Queuing);
string taskId = Helpers.GetSummarizeDivisionTaskId(extract.Id);
Console.WriteLine("Task Id: " + taskId);
string commandLine = string.Format("{0} {1}", SummarizeDivisionConstants.SummarizeDivisionTaskExecutable, extract.Id.ToString());
Console.WriteLine("Command Line: " + commandLine);
CloudTask unboundMapperTask = new CloudTask(taskId, commandLine);
//The set of files (exes, dlls and configuration files) required to run the mapper task.
IReadOnlyList<string> mapperTaskRequiredFiles = SummarizeDivisionConstants.RequiredExecutableFiles;
List<ResourceFile> mapperTaskResourceFiles = BatchHelpers.GetResourceFiles(containerSas, mapperTaskRequiredFiles);
unboundMapperTask.ResourceFiles = mapperTaskResourceFiles;
tasksToAdd.Add(unboundMapperTask);
}
//Submit the unbound task collection to the Batch Service.
//Use the AddTask method which takes a collection of CloudTasks for the best performance.
await batchClient.JobOperations.AddTaskAsync(this.jobId, tasksToAdd);
I have confirmed by storage and batch credentials are correct and functioning.
Any suggestions in determining why I am getting a BadRequest would be appreciated.

Fixed the problem. My Task id included the executable name, which had "." in it. Replaced the "." with a "-" and it worked.
An error is occurring when a client I'm using calls to Web Api. The problem is the stack trace I'm getting back is a bit unreadable, there are no line numbers so I am not sure where to look. This is it being returned as a Json response.

}
Is there a way I can config web api to return the line number where the error occurred so I can debug the issue more appropriately?
The issue was covered here : Stack traces with async/await
I'm currently usng .Net 4.5 yet the errors still get outputted this way.
I am use an extension that stores stack trace information inside exceptions, for example, original code:
try{
await NestedAsyncOperation();
}catch(NullReferenceException e){
Debug.WriteLine(e)
}
with readable stack trace:
try{
await NestedAsyncOperation().Trace();
}catch(Exception e){
e.Catch((NullReferenceException ex) => {
Debug.WriteLine(e);
}).RethrowUnhandled();
}
and output will contains stack trace with line numbers.
