here is the content of docker-compose.override.yml file:

version: '3.4'

services:
aspnetcoresample:
environment:
- ASPNETCORE_ENVIRONMENT=Development
ports:
- "80"
networks:
default:
external:
name: nat

i added a environment variable COMPOSE_CONVERT_WINDOWS_PATHS=1 and reset system but no success.
thank you for your workaround

This looks like it could be the same as #128, see my response there: https://github.com/Microsoft/DockerTools/issues/128#issuecomment-410750259

I changed COMPOSE_CONVERT_WINDOWS_PATHS from 1 to 0 and container creation was successful.
