Native messaging from chrome extension to native host written in C#

Question

I\'m trying to receive a message from my chrome extension via native messaging. The popup.html console indicates that the message is being sent, but my host is

Answer 1

In order to get my extension working, I followed the following steps:

1. I deleted my registry key and then re-added it in my HKLM registry.

2. Although unnecessary,host.exe really only needed to receive one message from the extension, so I changed my previous "open port" messaging to a "no port" message, i.e.

   chrome.runtime.sendNativeMessage(...);

3. Importantly, when I changed the text I was sending from {"text":data[0]} to a simple string {"text":"Hello from Chrome!"}, everything began working smoothly. data[0] was a string of about 250KB, which should definitely be an acceptable message size according to the developer's site. However, I have created a different question for this problem, as I was able to solve the general message sending and receiving problem I was experiencing.
