How to force VS2015 flush prebuild/postbuild output?

Question

Visual Studio waits for the prebuild/postbuild script to complete to show the output. Is there an option to force it to flush on new line for example?

Answer 1

I tested the behaviour with VS2010 and a small C# script started in a postbuildStep. My script writes several lines to the console, waiting 200ms after each line.

Yes. The output comes flushed in the output window, when the subprocess finishes.

Adding a manual Flush() after each WriteLine in the script does not help.

So this is a behaviour, I've seen, when starting a subprocess and consuming the console output via a simple ReadToEnd(). A correct implementation should use ReadLineAsync()

Seems to be standard behaviour in Visual Studio. I guess this is the way it was implemented in VS.
