You probably did something that Defender found suspicious, or maybe you used a 3rd party library that had malware in it.
Try making your application more simple until Defender complains no more.
Also scan your system for viruses.

More information here: Trojan:Script/Wacatac.B!ml threat description - Microsoft Security Intelligence[^]

It might also be a false positive, read info here: Windows Defender false threat on Windows 10 | Windows 10 Forums[^]

You can use OWASP Dependency Check to check your NuGet packages and 3rd party libraries, see: devops-security-tools[^]
