The executable of my core ASP.NET application was detected as a Trojan

I wanted to copy from a local publish location of my ASP.NET Core project to a production IIS server, and Windows Defender detected a Trojan in my main executable file. When I scan this folder on my local machine, Defender finds no threat.
Enter the image description here

I have created a deployment package in Visual Studio. There are no threats on my computer. I can only relate to the fact that the ASP.NET Core app creates an EXE file that opens HTTP ports.
Do I have a real problem or Windows Defender has no right regarding my application?
