Built-in messaging with .NET application on Windows

Question

I followed the documentation of natural messages to the best of my ability, but I can not get my native .NET application to even start working on Windows. When searching for more information, I noticed that some things are undocumented and unclear.

First, the documentation does not mention the requirement to add "nativeMessaging" permission. After that I got a little more; Chrome actually mentions a “New Background App Added” in a popup popup.

However, the following code is immediately disabled, regardless of what I tried.

var port = chrome.runtime.connectNative( ... );
port.onDisconnect.addListener(
    function()
    {
        console.log( "Disconnected" );
    } );

Based on my attempts to debug this thing, I have a few questions:

• On Windows, when does Chrome try to load manifests from NativeMessagingHosts into the registry? In other words, should you restart Chrome when the value changes, or just restart the extension in? "chrome: // extensions /"
• Absolute path in the registry, how to format it? . I saw people pointing only to "\\\\" slashes when path separators work. Do I need to use quotation marks?
• Is there a way to get more information about what is going wrong? For testing purposes, I renamed the registry key to see if I could get another error (assuming it could not load it would notify me of this). Instead, "onDisconnect" is still called.
