+# .NET Framework on Windows image
+
+This Dockerfile builds a Windows image (the big one, not Windows Server Core) with .NET Framework 4.8.
+
+The Dockerfile is based on https://github.com/microsoft/dotnet-framework-docker/blob/master/4.8/runtime/windowsservercore-ltsc2019/Dockerfile
+with a few changes
+
+```diff
+3c3
+< FROM mcr.microsoft.com/windows/servercore:ltsc2019
+---
+> FROM mcr.microsoft.com/windows:1809
+4a5
+> USER ContainerAdministrator
+```
+
+The main difference is that the big Windows image has the default user ContainerUser instead of ContainerAdministrator and therefore does not have enough permission to install software.
