I want to check the content of my docker container. I want to run a **powershell** or command prompt inside container so I can list directories. 

This container image is hosting **ASP.NET Web API** application using ASP.net **4.6.1** framework.

[![enter image description here](https://i.stack.imgur.com/Tpygv.png)](https://i.stack.imgur.com/Tpygv.png)

I ran following commands:

1. `docker container ls - to list conatiners`
2. `docker exec -i -t a1da40af6b3c powershell`

But nothing happens (as shown in the image). Am i missing anything?
