I am creating console application that does some file conversions. These conversions are easily done creating a model from the input file and then executing razor models for the output.
To have this working in the IDE I used Visual Studio 2015 preview and created a vnext console application that uses MVC. (You get razor support out of the box then). To get this all working you need to host the MVC app though, and the cheapest way to do that is hosting is through a WebListener. So I host the MVC app and then call it through "http://localhost:5003/etc/etc"
to get the rendered views that construct the output.
But the console app is not supposed to listen to/use a port. It is just a command line tool for file conversions. If multiple instances would run at the same time they would fight to host the pages on the same port. (This could of coarse be prevented by choosing a port dynamically, but this is not what I am looking for)
So my question is how would you get this working without using a port, but using as much of the vnext frameworks as possible.
In short: how can I use cshtml files that I pass models in a console app that does not use a port using the vnext razor engine.
Here is some code I currently use:
