SafeHandles | Unity Handles that can be | Plugin library

The situation is, I wrapped C# dll to use it in a C++ project and when I execute C++ project I can't see any sign about memory leak but the memory increases little by little. I think it's because the GC in C# library doesn't work in C++ project and I don't know how to solve it. Please help me.

My code is below:

1. C#

I am trying to change the console's color palette. To get this done I first need to Get my ConsoleScreenBufferInfoEx and then Set it. The problem is that I can't even get a valid ConsoleScreenBufferInfoEx from the STD_OUTPUT_HANDLE. The code below throws this error message:
System.ArgumentException: 'Value does not fall within the expected range.'
The handle is valid and yet I get this error. I have quadruple-checked every data type and related pinvoke entry - everything is looking good to me. There is no sample code for GetConsoleScreenBufferInfoEx and I haven't been able to find a working solution yet.

My sources:

• pinvoke: ConsoleFunctions (kernel32)
• msdocs: CONSOLE_SCREEN_BUFFER_INFOEX structure
• msdocs: COLORREF

Example App (.NET Core 3.1):
For this code to work, the project's build properties must allow unsafe code.
[Properties -> Build -> Allow unsafe code]

I'm trying to write directly to disk

I'm able to read, but I can't write.

Is there some specific function to write to file?

How to enable writing?

pinvoke´s signature:

I have a software library which targets console applications. I would like to run a slim set of integration tests that use the windows Console in a headless runner that would ideally be run on our build server and in the resharper test runner.

To make this work, I need the actual System.Console calls to be executed in the test (so they can't be conditionally commented out.)

When the tests call something that the requires the stdout handle, e.g. Console.SetCursorPosition, an exception is generated: System.IO.IOException: 'The handle is invalid'

I assumed I could just do a pinvoke and call FreeConsole and AllocConsole and this would allow me to call the relevant methods. Unfortunately this doesn't appear to be the case.

At the moment I can successfully Free, Alloc, and redirect console output back to STDOUT but this doesn't change the exception behaviour. Any ideas?

I'm redirecting STDOUT back to CONOUT using the following:-

I'm trying to use the following to continuously read data from a serial port:

I've got some working C# code to work with some Windows API calls (based on my Get-CertificatePath.ps1 PowerShell script), but the F# version fails. I'm sure I'm missing something, most likely an attribute, but I haven't been able to figure it out.

Is there a way to get the F# version working?

Run using csi.exe from the microsoft-build-tools Chocolatey package.

I'm want to get c# object inclusive size by using clrmd API. In order to get this information, first I need to attach to the process. To achieve this, I'm using DataTarget.CreateSnapshotAndAttach method.

For some reason, the application crash after getting System.Runtime.InteropServices.SEHException exception with 0x80004005 Error Code

StackTrace:

Im aware of the dispose pattern and would like to properly dispose my Socket resource. In the documentation they recommend to use SafeHandles, but I'm not sure how exactly this works with System.Net.Socket. I discovered that the Socket class itself includes a SafeSocketHandle, but I have no idea how to use it. Do I need to dispose the handle and the socket or is it sufficient to dispose only the handle? And I assume in the class I'm only using the handle for socket operations, right?

While I am still learning System.IO, in File Stream class 's constructors, I found that there are overloaded constructors with the type named SafeFileHandle, I tried to search on the internet and the MSDN Documention, but I can't understand anything, and I found even stranger words, like IntPtr, can any one explain it to me?
