Attach to MVC 6 process in IIS - asp.net-core

I am hosting an asp.net 5/mvc 6 application in local IIS using dnx x64 1.0.0.rc1. I would like to attach to the iis process and debug my application, but no symbols are ever loaded for the classes that I set breakpoints in.
Is this possible with this version of dnx and IIS?
If so, how do I attach to the iis process with symbols loaded?
---UPDATE
So I've tried attaching to dnx.exe, but still no luck. Strangely, I was able to get this to work one time, but cannot replicate it again. So if anyone can outline the steps required to debug MVC 6 on IIS, please post here.

What process are you trying to attach to? I believe you should be attaching to dnx.exe

Run exe file alongside .NET Core Web Application

I have an executable file which I would like to run alongside a .NET Core web application. It needs to start when the web application loads and will continuously run until the web application ends. I also need to be able to check if the executable file is still running through the UI, and have an option to start, stop or restart.
I have done a bit of googling already on this and all that keeps returning is examples where the exe file is expected to end at some point, not anything that continuously runs.
Any pointers in the right direction would be great.
Andy's comment is correct. It's recommended to using Background tasks with hosted services in ASP.NET Core.
And you also can use signalr to record the status of your service. You can start, stop by using StartAsync and StopAsync. And it's impossible to restart. The background service was launched with asp.net core.
For more details, you can check the blog:

ASP.NET Core 6 site work with kestrel not with IIS or IIS Express (503)

I'm working on an ASP.NET Core 6 site and I usually use kestrel to run and debug the application. Today I've deployed the app to IIS but after one or two requests IIS stop responding and only return
HTTP Error 503.0 - Server has been shutdown
Same behaviour with IIS Express. Everything works fine with kestrel.
I don't know how to debug the problem, I've attached the debug but with no luck. I've also looked at stdout log but nothing appears.
Does anybody have any suggestions on how to debug the issue ?
Please follow my step to collect the dump files. And if want analyze the dump files you can create a new post and ask for help. This answer just tell you how to debug issue.
First Way
Remote debug with visual studio 2022
Deploy your app to IIS.
Run your VS2022 with administrator and attach the process.
Reproduce the issue to check the issue.
Second Way:
Collect dump files
If the first method can't reproduce or debug the issue.
You can follow below steps to collect the dump.
Download and install Debug Diagnostic Tool v2 Update 3.1
Deploy your webapp in IIS
Set rules to collect dumps by using DebugDiag or Collect dumps manually

Running winforms client, does not start iisexpress with the referenced wcf service - under Windows 10. Ideas?

I have a vs solution with 2 projects - WinForms client, and WCF Service.
Since visual studio 2013 to 2019 (I was under Windows 7), every time when I ran in debug the WinForm client, VS automatically was starting the IISExpress in background(I want that!), and my calls from the client were successful, stopping on breakpoints inside the WCF service easy.
Last week, I got new box with Windows 10. Now when I start the client, there is no iisexpress.
The source code is the same and not changed - my co-workers are under Windows 7 and this works for them - same code - we use git as version control.
The only time I see iisexpress is if I do "Update Service Reference" or I make the WCF startup project and run it.
Can you help me identify why this functionality stopped working? Ideas for a fix?
Windows 10, Visual Studio 2019 Enterprise, .NET 4.6
EDIT: I do not have problem running the webservice in IISExpress, when i specifically run it - it works, also on solution level if I set 2 startup projects, all will work. The main issue is that with Single Startup project - thw WinForms client, Visual Studio will not bring up the IISExpress instance. It is only development time issue, and this works for my co-workers.
The solution is in the VS generated (regenerated if missing) user file in the WCF project
.csproj.user
there is property
<AlwaysStartWebServerOnDebug>True</AlwaysStartWebServerOnDebug>
It must be True, but now it is defaulted to False.
The *.user files do not go to version control, and if they are missing VS regenerates them, hence my coworkers had it, and my freshly cloned repo did not.
I'm pretty sure I never touched this file or did any configs like that on the WCF project, my suspicion is that MS decided to start defaulting to False in some version or patch.
WARNING! After changing the option, close/open the entire solution or restart VS.
Disclaimer: I found this solution in the build in VS report problem button leading to a portal with reported problems and solutions. I do not see how to copy link or anything from that Feedback tool, but this is the guy that deserves the credit: 佐々木隆幸
It seems that you want to debug the WinForms application separately regardless of the WCF application. we could set up the project dependencies in the property page of the VS solution.
Then open the SVC file, press F5 to launch the WCF application so that we can add service reference in WinForms application.
Please ensure the below configuration in the property page of the WCF application project.
Besides, if there is something wrong with the IISExpress, we could opt to repair the IISExpress in the below dialog.
On my side, it works like a charm.
Feel free to let me know if the problem still exists.

Deploy MVC 6 app in IIS

I'm using Visual Studio Express 2015RC and I created a simple MVC 6 application, but when I try to publish it I don't see the option to deploy it to IIS, I see the options Microsoft Azure Web App, Import and File System, I tried the File System but It looks like it is more for creating stand alone applications to be launched from a console, now, when debugging I can select IIS Express or the web command, there is no IIS option, so the question is, how can I deploy the MVC6 web application I created to IIS?
File System publish is actually exactly what you want; All DNX applications are stand-alone, whether for ASP.NET 5 or a console app.
When you publish to the File System, you get a few folders; the wwwroot (assuming you kept the default in your project.json) folder is where IIS should point. The web.config in that folder is generated for you automatically assuming you keep everything else where it is.
For what it's worth, the official documentation will probably be here, once it's written. Also, on Stack Overflow, ASP.NET 5 project hosting on IIS probably has some useful information, though it looks like it's a bit out of date at the moment.

wcf : Service + Client in same solution, how to debug? I don't want to run 2 versions of VS 2010 at the same time

I have created an application which has a client (WPF) and the Server (WCF), the service is IIS hosted, currently I am having to have 2 versions of vs 2010. One loads the wcf service in IIS and the other in my windows application.
The problem with this is it takes so much resources.
It appears if the wcf service is "NOT" hosted in IIS then I can start two projects at the same time according to this http://msdn.microsoft.com/en-us/library/bb157685.aspx
But what are my other options?
I need to find the best way of being able to compile / run the 2 projects and able STEP INTO each when when in debug, without using too many resources or having more than one vs 2010 open at the same time.
You should be able to debug both from the same instance of Visual Studio if they are in the same solution. When you run your application from Visual Studio, open the Debug menu and choose Attach To Process, you need to attach the debugger to the ASP.NET worker process (aspnet_wp.exe), it should automatically attach to your client.
Open service and client code in VS. Open Debug menu. Attach to process. Hold the Ctrl key and select as many processes as you want to debug using Mouse click.
In your case, you can select the ASP NET worker process depending on the version of IIS and the client process.
The easiest way to debug your WCF service is to:
Right click on project containing svc file.
Select Set as Startup project.
Put a breakpoint on the methods you want to debug.
Breakpoint should be Red.
Make sure your app config file is pointing to the debug WCF service version that's currently running, ex:
http://localhost:12345/MyService.svc
Run your app.
When the app calls that WCF method, it should stop on breakpoint.
