ANSWER
Answered 2019-Nov-14 at 06:06That's an expected behavior. Cause you are trying to use MSBuild command to build the website project (metaproj). Then it creates a PrecompiledWeb folder and places the code in there.
After creating a publish profile in Visual Studio the following are created:
1) A publish profile (.pubxml file) under App_Data/PublishProfiles
2) A website.publishproj in the root of the website
The purpose of the website.publishproj is to facilitate command line publishing. Then you can try to use command like the following:
QUESTION
This method is freezing my GUI and I don't understand why.
Specifically it's getting stuck in while ((feedback = reader.ReadLine()) != null)
I've tried breaking out of the loop by checking reader.EndOfStream() with the same result. The printer is behaving as expected and printing the label, and the expected feedback is also being returned. It just sits in the loop, blinking a cursor in the console.
I can get rid of the loop, as I don't really need the feedback for this program, but I would still like to understand what's happening.
It's being called like this:

Answered 2017-Mar-21 at 16:28Excerpt from MSDN:
A line is defined as a sequence of characters followed by a line feed ("\n"), a carriage return ("\r"), or a carriage return immediately followed by a line feed ("\r\n"). The string that is returned does not contain the terminating carriage return or line feed. The returned value is null if the end of the input stream is reached.
You probably haven't reached a \n
, \r
or \r\n
nor the end of the input. The caveat here is that normally "end of the input" means that the other point (the printer in your scenario) closes the channel and most probably it is not doing that.
I recommend using timeouts on the reception as those devices normally send all the data at once. There are other options if this one is not valid, just ask, but it should work most of the times.
