Q: Compile a single C# file using DNX/DNU Is it possible to compile a single C# file using the new .NET cross-platform toolchain (DNX/DNU) without first making a project.json file?
For example, with Mono you can do:
mcs Program.cs

The mcs command creates Program.exe if it finds a Main method otherwise it creates Program.dll.
I'm trying to build on Mac and Ubuntu using the open source Microsoft tools instead of Mono. I make a ton of tiny little programs for demonstration purposes and I don't want to have to create a project.json file every time.

A: I dont think that is possible. You would need project.json to build. 
If you try build Program.cs without project.json through dnu you would get "Unable to locate project.json"
PATH TO PROJECT>dnu build

Microsoft .NET Development Utility Clr-x86-1.0.0-rc1-16231

Unable to locate project.json.
