Why does a simple .Net Core 3.0 WPF app not start on a deployment computer

Question

Created very simple WPF .Net Core app with VS2019Prof V16.3.1.

• Created new project - WPF App (.Net Core)
• Nothing else was done, just only built the project (Debug and Release) - successfully run it on 'dev' computer Win10 V1809 (Build 17763.740)
• Copied debug and release folder to 'client' computer Win10 V1809 (Build 17763.740)
• Installed .Net Core 3.0 Desktop Runtime on 'client' computer
• rebooted client computer
• tried to run debug and release version

Just no reaction when starting the app. ... tried to observe anything with SysInternals ProcessExplorer, it starts and immediately stop. No crash message, ... nothing...

What else could I do to narrow down the reason why it doesn't start?

Answer 1

Found and tested two solutions:

• Install .NET Core SDK instead of .NET Core Desktop Runtime
  See https://dotnet.microsoft.com/download/dotnet-core/3.0

• Deploy as self-contained app
