There is problem with hosting application on IIS by VS2017 (15.9.3). I have MVC app write in .NET Core 2.0 with enabled logging on web.config
stdoutLogEnabled="true" stdoutLogFile="c:\Logs\log.txt"
After any request is made I get 502.3 error.
HTTP Error 502.3 - Bad Gateway The specified CGI application
encountered an error and the server terminated the process.
On my log file there is short info:
Process is terminating due to StackOverflowException.
On EventViewer I get more descriptive error:
Faulting application name: w3wp.exe, version: 7.5.7601.17514, time

Report Id: f7ca32d0-f31c-11e8-83db-1c4d70da3d0a
Exception is probably generated by something in my code, maybe configuration of sth is wrong, but how can I find reason of it?
What could be the best strategy to find solution?

Using StoreContext.CanSilentlyDownloadStorePackageUpdates when the network is disconnected will cause the app to crash, and I try to use Try-Catch to fail to catch this exception.
In addition, when I use StoreContext.TrySilentDownloadStorePackageUpdatesAsync to download the update package, disconnecting the network at this time will also cause the APP to crash too.
Code snippet:
[System.Runtime.ExceptionServices.HandleProcessCorruptedStateExceptions]
public bool CanSilentlyUpdate()
{
try
{
//There will be an error:
// System.AccessViolationException :“Attempted to read or write protected memory.
// This is often an indication that other memory is corrupt.”
return StoreContext.GetDefault().CanSilentlyDownloadStorePackageUpdates;
}
catch (Exception ex)
{
Debug.WriteLine(ex);
return false;
}
}
The following is the error log in Event Viewer:

This kind of exception seems to be unable to be caught using managed code, what should I do?
After discussing with other engineers, it looks like there is no other way to handle it.
This method should be running in the background so that you could not catch it in the UI thread. It essentially bypasses any chance dev has at handling the exception.
Our suggestion is that you need to check the network before calling this method and give a tip when calling this method to tell the user to keep network connection. And you could try to subscribe to the NetworkInformation.NetworkStatusChanged Event in your app.
I run my program in visual studio and it works great, but when i publish it and installed it dont start. I checked the problem on the event viewer and it's the information that comes with the error:

Please look into your code, you are using file which is not available while publishing. you can copy the file into the root directory and try it again
I am working on a VS 2015 MVC C# web application for a client. The application has been stable for a couple of years, but the client has asked me to integrate some C++ DLLs that perform engineering calculations relevant to our web application.
Unfortunately there is no source code and documentation does not exist (don't ask me why...). So I am somewhat blind to how to use these DLLs.
When I load the main DLL and attempt to use it I get the following error:
Failed to load library SQLite3Ex.dll

I'm not sure how to troubleshoot this problem and was hoping someone could point me in the right direction. I think this is a general error - could be a missing .cfg file or even a missing DLL? But I'm not sure how to determine the problem.
Trying to publish my UWP app. I'm able to build Release versions fine (I was actually able to push to the Store), but my app crashes as soon as it's launched. But the debug works fine?
I'm getting this error when debugging a Release build:
Unhandled exception at 0x55BA32F9 (Windows.UI.Xaml.dll) in AppName.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x00A12450, 0x00000002).
And these errors in Event Viewer if I launch it outside of VS:
1st:

Is there something I'm doing wrong? I don't get any errors or warnings on Debug.
Add some code to the app.xaml.cs files unhandled exception event to send the error text to a web service or something like google analytics so you can see what is happening
Ended up being an issue with Entity Framework when it is compiled in .NET Native. I had to switch to SQLite for what I was using it for. Seems to work fine now.

0xc00000fd indicates a stack overflow.
Are you calling Win32 apis using p/invoke?
Can you add some logging to the application and see how far it gets before faulting
Does it fail when running as an application (not as a service?)
