# PowerShell does not currently have a good way to do the POST in the required format for
# making use of the Bikeshed public web API. Therefore, we use a C# class to do what we need.

# The goal is to emulate the following:
# curl https://api.csswg.org/bikeshed/ -F file=@Cpix.bs -F force=1

# Currently this is only needed for PowerShell Desktop because PowerShell Core has some default list we need to use.
