Windows Firewall Notifier 2.5 Beta

About this release
This is the first beta release of WFN 2.5, with huge changes:

migrated to .NET 5.0 (the alpha went through .NET Core 3.1 first, but 5.0 was here so... why not)
new layout and design.
fixes and improvements.
an important one (do not miss it!): Notifier will now run in the background and will stay open, if you enable notification. This fixes all CPU related issues, and multiple Notifier.exe process spawning as well. Please tell us if the "old mode" was best for you, I might reintroduce it later.
libraries updates (note: the used libraries and dependencies will be added soon in the about page - the main change being Oxyplot for the bandwidth graph instead of a custom one).
Versions
You can either pick the AnyCPU build (if you already have .NET 5.0 installed), or the x64 / x86 builds depending on your CPU if you want a standalone version (which also offers better performance).
Please note that the IP database is always embedded, if you'd like a lighter version without it, feel free to tell.

Disclaimer
As usual, this is a beta release, not all cases have been tested and you might encounter unexpected behavior. Please report them in the Issues page (or open a new discussion through the new GitHub feature if you have some ideas, improvements, and so on!).

Services selection window now working. If multiple services are detected, you can now select to which services to apply the rule!
Small improvements to service detection code. It should now be even more reliable in detecting services.
Improved selected port filter on rules. Don't select local port checkbox or protocol checkbox by default when they don't make sense.
Enable long path support. WFN will now handle long paths properly.
Fixed a couple of cases where the notifier would not pop up. Fixed a couple of crashes, race conditions, and other bugs related to the notifier popping up.
Slightly reduced memory usage of WFN.exe.

New in this release:
Fixed the owner column. This got broken in V2.0 Alpha 5.
Fixed crash on Windows 2008 due to missing registry key.
Fixes to service detection code. It now works with any OS language.
Fixed the log file sharing mode. This should vastly reduce error when trying to write to the logfile.

New in this release:
New settings management and logging logic. Settings are now specific to users as they were supposed to be (accent color customization, animations, etc.).
Note: logs can be temporarily found in Wokhan.WindowsFirewallNotifier.Common.log. This will change in the next version. Please be aware that logs can grow faster in this release, either in the WFN folder and in the %LocalAppData%\Wokhan Solutions\WFN user's folder as well.
The multiple notifier.exe spawning bug SHOULD be fixed or limited. I think I understood what was happening, so if I'm right it won't happen again. And if I'm wrong, well... it probably will... :-/

The following was already in the previous alpha:
Bug fixes and performance improvements. The Connections page should load faster, as well as the Map (which should now refresh every 1s by default without any lag).
Added an option to switch to Aerial view in the Map.
Bandwidth page modifications. Still to be improved, though.
Connection page should work better with non-admin accounts. It now uses WMI to retrieve processes information.
More polished version. Could have been a beta, but I still need your feedback before considering it as stable enough.
New Firewall settings page. To allow managing the Windows' firewall directly from WFN, and to ease the notifications settings (no more weird and hardly understandable settings as in the previous version).
New icon. Yeah, it's important. Don't tell me you don't like it, while it took me almost 35 minutes to create that one, I'm pretty proud of the result ;-)
New UAC handler. The previous method was a workaround (using an additional and now removed EXE for which UAC was required) and the detection was not working properly. It now uses a better method, meaning that you can use the usual "run as admin" command (or launch WFN.exe and then click on the "restart as admin" button).
New toggle buttons. More "Windows 10" like.
Brand new design. Hope you'll like it, as it's more "modern". If you don't, please be constructive and explain why.
A new map feature allowing to see where your connections are actually linked to. I'll add the ability to locate a given IP soon. The map also allows to compute full routes (i.e. to check what places a connection is going through before reaching its target), it's really fun to see it in action. Note: the map feature is still a bit SLOW and requires a huge database to be loaded in memory, meaning that the WFN console will use way more memory when using this. I'll try to improve this later.
A new Bandwidth usage page with a real-time graph. Values might be buggy in this release, and it's clearly unfinished.
A new Adapters page showing detailed informations about your network interfaces. That one needs some polish as well.
The console now runs without an admin account, but in limited mode. Some of you asked for this, so I implemented it, but launching it without an admin account is like swimming without using your legs. It works but has some serious drawbacks (protected processes cannot be accessed, some information cannot be retrieved, etc...).

Under the hood:
Switched from Forms to WPF, which means better maintainability, less code, cool visual effects (while I didn't add any, it's easy to do so), improved performance...
Upgraded to .NET Framework 4.5 (instead of 4.0). If you don't have it, the app will crash when starting, so check this requirement before telling me it doesn't work.
Many other changes, fixes, etc....
Compatibility

Since I'm using Windows 10, you may encounter some issues with other versions (I cannot test extensively on all and every systems). If so, please tell me. Regarding Windows 10, it seems everything is working, except when debugging through Visual Studio (so you shouldn't face any issue, except if you download the source code and try to run it from there). By the way and on a side note, I hope you all planned to upgrade to Windows 10, as it looks like the best version ever (even with the preview!).
Known issues

I forgot I put a hard-coded IP as a starting point in the map, so connections routes are all starting from France. Will fix this ASAP. FIXED in 5641.20191.
Some features still need to be improved (ex: event log page, firewall rules), I'll work on that before the beta is released.
The notification window is partly broken as I did not re-implement the service detection yet. I'll do it next week. If you are using the service detection feature, I advise that you don't upgrade yet. PARTLY FIXED in 5647.32777. I mean it's here, but I did not test all cases yet.
The connections routes on the map don't refresh themselves properly. You'll need to drag the map a bit for them to appear. I still need to figure out why this is happening.
This version is available in English only (translations will come later), and some English labels are missing anyway. Please don't pay attention to those ones.
Logs are disabled in this release. Since there are a lot of "hidden issues" (mainly due to non-accessible processes or connections), logs were growing too fast. I'll provide a way to temporarily re-enable them soon as it would be helpful to investigate. LOGS ARE BACK IN 5666.33881. You can find a corresponding option in the Options page.

Features
Changed the "single instance detection" code to something supposedly more reliable (and the code is cleaner and easier to understand that way, no more Mutex and cross-processes messages). It should help getting rid of the "omg there are thousands of notifier.exe processes trying to kill my computer" syndrome ;-)
Added an option to minimize the console to the system tray (check the notifications options)
The notification will now remember if you lastly displayed the detailed dialog or the simplified one. I think it's more user-friendly this way than using a dedicated option.
Some other minor tweaks.
Edit: I forgot to tell I added a way to copy the information from the notification as well. Just right-click on pretty anything to get a menu (only copying is possible as of now).

Known bugs
If you open the console with an admin account (not the one you're logged in with), the settings (animation & alike) won't be applied for your logged-in account. I'll fix this another day...

что это...

Fixed a bug for people using multiple screens (the animation was weird).
Modified the service handling: many services were wrongly detected, creating bad rules (explaining why some people always get the same notification while creating the corresponding rules). When the service cannot be determined, a new window offers to select which one(s) should be considered when creating the rule.
Fixed some bugs here and there.

This minor update includes:
- new layout and animations for the Notifier popup.
- modifications to allow using Windows's high contrast mode (and alike) for people suffering from eye disorders (Chuck, this is YOUR release ;-) ).
