I am developing a computation and resource heavy back-end .NET Core console application that runs continuously in the background. In Windows, this console application will run as a Windows Service using something like NSSM. In Linux, it will run as a daemon.
In order to configure this background application, I would like to provide a Razor-based HTML5 GUI. In principle, this is similar to how a house-hold router works -- runs in the background and provides an HTML admin GUI.
QUESTION 1: Is it possible to achieve this?
QUESTION 2: Can you provide general outline of the startup/config code to make this work?

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:

I have an application that is a Windows Service application. It currently reads an XML file for it's configuration and the code works off those settings.
I have created a separate project that is a Windows Forms application (typical windows app). This app is a GUI interface into the configuration settings (changed from XML to database, but that is relatively unimportant).
What I need to do is:
Integrate the 2 projects
Add a system tray icon to pop up the form
I'm unsure exactly how to proceed on this and wanted to get some advice before messing things up.
You can't integrate these two things (entirely). A service is designed to run without a GUI of any kind (there is a work around to allow desktop interaction but this is messy and clunky and will cause you more problems than it solves)
It sounds like you just need to use the code from the service in the forms application. This should be a simple copy and paste operation.
To show an icon in the system tray is pretty easy:

I've downloaded and installed the windows 8 consumer preview, and I'd like to figure out how to use the UI Automation API's to get data from metro style applications.
Background: I have a lot of automated tests which use the Microsoft UI Automation API's to interact with applications. The scripts are written in IronRuby against .NET 4
Initially, I'd simply like to check if the start menu is visible (and if so, close it)
According to Microsoft, the normal UI Automation API's should be able to access and control metro style applications, but the problem is, I can't figure out how my code can actually access the UI of metro applications? Our normal way of viewing UI automation data is using UISpy, however when I run UI spy under windows 8 and bring up a metro app, there is no mention of it... it seems like metro apps (including the start screen) are walled off from the desktop.
If I can't find the metro apps in UISpy, how can I find what their automation ID's are, and how could I find them from my automated test scripts?
A few resources on UI automation which works in Metro style apps:
Here is a sample demonstrating it.
Here is a blog post explaining it.
This is a forum thread on the subject.
There is nothing about the app that stops traditional UI automation from working correctly. You may have to get updated tools to view the Metro style apps. Some ship with the Consumer Preview. Look for inspect.exe.
UI Automation tools can automate Metro applications. Check RIATest for example.
Stating from version 6.0 a number of features in RIATest are specifically targeted at Metro style application automation, particularly:
Ability to stay on top of Metro UI to allow you to simultaneously see your Metro application and RIATest IDE and minimize switching from Desktop to Metro screens when automating a Metro application.
Recording of actions performed on native Windows GUI elements (including Metro GUI). The recorder analyses your script code and reuses your variable names to generate cleaner recorded scripts similar to how you would hand-code an automation script.
Seamless workaround for bugs like this in Windows UI Automation implementation in Metro UI.
Disclaimer: I work for Cogitek, the RIATest company.
WinRT (aka "Metro Style") applications run in an sandbox. You cannot pierce the walls between applications, including to Desktop applications. This includes network isolation (you cannot refer back to localhost for example except in a development environment). There are a couple of exceptions to this such as the Share and Search contacts which allow for very specific types of interactions between apps.
It is this sandbox that is preventing UISpy from seeing the executing WinRT application in the background. I'm not sure how UISpy could work around this issue without some kind of development environment exception to the sandbox (similar to the network isolation exception) that isn't available in the consumer preview.
I'm also unaware of any announcements regarding when/if the UI Automation API will be supported for WinRT applications at this time.
I have a dynamic library, I intent to inject in running application & newly launched applications.
I can inject it in running applications with the help of a process running with root user permissions.
Now I am trying that library should get loaded as soon as application is launched. I know one such library capable of doing this called, application enhancer. I am looking for similar behavior.
Does anyone has an Idea how can this be achieved?
Look at SIMBL agent code. It adds a observer to application launch notification and then injects. You can follow the same approach.
I have mobile web application that has offline capabilities (via HTML5).
I'm currently building automatic build & testing for it (ant, JsTestDriver etc.), until I hit a wall. How can I test if the web application has working offline mode? This is specially painful since if tested by hand; iPhone practically needs full reset between tests (it tends to cling on to some parts of the data).
I'm thinking something around these lines (on a idea level):
Setup Java web server with ant
Fire some sort of headless client, that supports HTML5 offline use
Load the application
Validate that everything is loaded
Disable server
Load the application
Validate that everything is loaded, still
Any suggestions how would I proceed doing something like this?
Not sure I understand your question, but what do you think of:
Not using an iPhone, but chrome on PC with the ripple emulator http://ripple.tinyhippos.com/
Setting a fake proxy or editing the .host file in order to be sure that your chrome session does not have access to your server.
