what version of mono do you run?
how have you installed mono?
install the mono-complete package if you haven't done it already:

sudo apt-get install mono-complete

then restart HS4

it that still doesn't work, try to delete System.Net.Http.dll from bin/PhilipsHue, then restart the plugin.

[JoelWener]

Mono was installed with the O/S. (Pie). Version 5.18.0.240+dfsg-3

[JoelWener]

After removing the file. Received error message could not set parent class q42.HueApi.BridgeLocator as system.Net.http could not be loaded

[spud]

Mono was installed with the O/S. (Pie). Version 5.18.0.240+dfsg-3

did you try this:

 
 sudo apt-get install mono-complete

then restart HS4

it that still doesn't work, try to delete System.Net.Http.dll from bin/PhilipsHue, then restart the plugin.

[JoelWener]

Hi,. Yes mono-complete is installed, I had previously executed the command.

[JoelWener]

I would just like to mention that I am currently running .13 of the plug-in, and HS4 Beta 4.0.4.0 as it has changed from the original post.

As per above, I have tried everything you have asked to no avail.

Regards
Joel

Is there anything else ?

[spud]

I think you are running into this bug: https://github.com/dotnet/runtime/issues/21777

The solution is to update to mono 6, I have mono 6.8 and I don't see this error

If you can't update mono or don't know how to do it, the possible workaround is to use System.Net.Http.dll from mono and not the one installed in bin/PhilipsHue, that's why I tried when I made you delete this file in bin/PhilipsHue, but I don't know why it's not working for you so please do the following:

run the following command to find if the mono dll is installed on your system:

ls /usr/lib/mono/gac/System.Net.http

then instead of starting the plugin from the web interface, please start it from the command line using the following command:

 sudo MONO_LOG_LEVEL=debug mono HSPI_PhilipsHue.exe | grep System.Net.Http

then post what you get in the console when you try to add a bridge

I have same issue and my mono version is following

root@krunal-MintOS:/home/krunal# mono --version
Mono JIT compiler version 4.6.2 (Debian 4.6.2.7+dfsg-1ubuntu1)

when I run sudo apt-get install mono-complete it says I already have latest version so how can I upgrade to mono 6 ?

I'm going to fix the plugin so that it can run without upgrading mono. Stay tuned

I fixed the problem in PhilipsHue beta 4.0.14.
However for the fix to work, you might need to delete bin/PhilipsHue directory before installing the new version.

Hi Spud,
I installed a new version after deleting existing bin/PhilipsHue but still getting the same error
