I have a Console Application and a Library.
The Library contains the PropertyChangedNotificationInterceptor class and all the code to handle Property changes.
The Console Application has the properties that are supposed to trigger the Interceptor, but it doesn't trigger it.
I put the FodyWeavers.xml in both projects, so the Console Application is able to trigger it. As the Interceptor isn't part of the Console Application, it doesn't appear to use it.
Is it possible to make the IL work on the Console Application or is that a C#/Visual Studio limitation that I need to work around? If so, does anyone have a good workaround that has a low impact on the Console Application?

I want to make a GUI Windows application that can run console applications. When this happens, the console window should not be shown. Instead its content should be shown in a visual component (memo/richedit). This component should show exactly the same content which would appear in the console window, even the color of the text and its background should be displayed. So this visual component should work exactly as a console window. I know that the standard output can be captured but many console applications do not use it. Is it possible to capture the output of a console application this way? Are there Windows API calls that can handle this?
I use Delphi XE2 but C# code would also be helpful.
You have to run the console mode program with stdout redirection to a pipe that your Delphi program will create. Your Delphi program can read the pipe to get the console mode program output and do whatever it needs to. By the way, this works not only with Delphi but also with any language able to create pipe and run program with I/O redirection.
If you need Delphi code to do that, have a look at this reference.
There is a ready-to-run component on GitHub: DosCommand
The Demo shows two ways how to do what you describe.
I am not sure if it works for older versions like XE2, but at least you can give it a try.
Traditionally you would call CreateProcess with stdin/stdout set to pipes you created. This should work for most programs but not for anything that uses a ncurses style "GUI" and you also lose the color information. An example can be found on MSDN.
Windows 10 (1809?) added support for pseudoconsoles. This is used by the new Terminal application and is your best bet for full console compatibility.
The last alternative is to inject into the child process and hook WriteFile, ReadFile and all the console functions but this is ugly and error-prone.
I need to write a very small application which writes some system data to a file and then exits. I could do this in a console application but I have no need or desire for a console window to appear during this process.
I would normally use a Windows Forms application with no forms, execute the code in the Main method and then allow the application to exit, however, this time I couldn't help but wonder if this is the best way to do it and whether you could do it with a WPF application instead, what the differences are and whether or not once you've remove any forms/windows and unnecessary reference, it matters or not.
WPF and WinForms are two different libraries that show UIs.
If you never show a UI, you aren't using either of them.
You should start with a WinForms project (WPF projects set extra project metadata that you don't want), then delete the reference to System.Windows.Forms.dll.
Alternatively, start with a console project, then change the Output type to Windows Application.
Windows Forms with no window or console app with the type changes to windows application will give you the same result which is a simple app with Main() method and now windows.
WCF will only make sense if you actually want to display something as you're not going to use any of its features in your case.
I was wondering if it is possible to open a second project (in the same solution as the first one) by code in the first project.
For example i have one form application project and another console application project.
The form application starts and when the user clicks a button i want the console application to run and the form application to stop.
Or could someone tell me how to delete my application .exe file?
The projects don't need to be in the same solution to do that. Just use Process.Start to start the executable for another application, and then close the main form to end the current application.
If you don't want to run the code as an entirely different process then it may also make sense to have a 3rd project that is a "class library" that the other two projects could add a reference to. This would allow you to define common code used in either application, using classes that are generalized to be helpful in either project.
I'm not sure what you're trying to do; but Process class has Start and Kill methods that will let you launch / exit processes.

I've got a console application and I want to run it from another application. But when I invoke it from code--to call program I use ActiveXObject--it shows the console. How do I get it to not show the console? I mean, the program works but console is shown.
If you make the application a Windows Application instead of a Console Application it will not show or open (or use) a Console. Your code can stay the same - and the application will still function (without ever creating a Form or Window).
That being said, if you control the "other" application, you may want to consider making a class library instead of a separate Application. This would allow you to just include and run code within the library without starting a separate process.
You can create it as a Windows Forms application with a hidden window. That's just one possibility like Reed Copsey pointed out, i used it once because i needed to process some specific Window Messages.
I have a C# Console app than runs a pre-build step (to get NuGet Packages).
When I am debugging this, I want to pass in a parameter and show the console. When I am not debugging it I don't want to see it. I don't even want it to flash up there for a second.
I have found ways to hide it, after it has shown. But I can't find a way to never make it show unless I am willing to change it from a console app to a Windows app. (Which I would do if I could then find a way to show the Console when needed.)
Build as a Windows application and show the console when you need it. To show the console when needed use P/Invoke to call AllocConsole (pinvoke.net has the declaration you need).
(Console sub-system processes always get a console, their parent process's if there was one, otherwise a new one. This is the way Windows works at a deep level.)
Use FreeConsole WINAPI function:

Another solution is to simply switch to a WinForms application as project type. No console will be allocated then (and you do not need to show a form).
