Can you post me screenshot from your network adapters in windows?

I got another report via Reddit, but i can't reproduce.

[egnirra]

Sure.

[deaquino]

I attach mine, I have the same issue.

[BornToBeRoot]

I installed some of these tools to add network interfaces to my virtual machine, but without success... i still can't reproduce.
The execption is thrown when selecting a network interface on start, but i don't know in which line / property.

I changed the version here, that the error is intercepted and one or two MessageBoxes are displayed.
Just open the NETworkManager.exe and you should see a MessageBox.

NETworkManager_v1.6.0.0_DEBUG.zip

Maybe someone with the problem has installed Visual Studio 2017 and could also debug it ?!

[deaquino]

I'll try it in few hours.
Thanks

[egnirra]

The debug version starts for me.. strange.
The normal version does not work still.

[BornToBeRoot]

Indeed strange...

Does it show a MessageBox?

[egnirra]

No i didn't get anything :/ I can test more after I get home from work, I'll test on my laptop also.

[egnirra]

It seems to work fine on my laptop, I'll test more when i get home.

[deaquino]

It´s in Spanish...

[deaquino]

value.IPv4Gateway is not null but it´s an empty collection, so value.IPv4Gateway.FirstOrDefault() throws an exception.

[egnirra]

It must be possible to set a default value if it's empty then? :)

[deaquino]

Fixed here: #86

[BornToBeRoot]

Yep. Line 164...

@deaquino thanks!

[BornToBeRoot]

#86 merged.

I will release a new version in a few days, with some bugfixes.
