Linux build instructions fail

[duncanawoods]

OS: Ubuntu 18.04 dotnet sdk: 3.1.100

The build instructions:

sudo apt-get update && sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev
cd testassets/HelloWorldApp
dotnet run

yield:

Unhandled exception. System.DllNotFoundException: Unable to load shared library 'WebWindow.Native' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libWebWindow.Native: cannot open shared object file: No such file or directory
   at WebWindows.WebWindow.WebWindow_ctor(String title, IntPtr parentWebWindow, OnWebMessageReceivedCallback webMessageReceivedCallback)
   at WebWindows.WebWindow..ctor(String title, Action`1 configure) in /home/duncan/Projects/github/WebWindow/src/WebWindow/WebWindow.cs:line 133
   at HelloWorldApp.Program.Main(String[] args) in /home/duncan/Projects/github/WebWindow/testassets/HelloWorldApp/Program.cs:line 12

The build doesn't fail:

dotnet clean
dotnet build

Build succeeded.
    0 Warning(s)
    0 Error(s)

But it doesn't build the native library as the readme claims. I was going to be surprised if it did because I don't expect dotnet core to build vcxproj files. Trying to build the native project directly generates an expected error:

cd src/WebWindow.Native
dotnet build

Confirm that the expression in the Import declaration "/Microsoft.Cpp.Default.props" is correct, and that the file exists on disk.

Build FAILED.

Thanks! I've updated the instructions.

Perfect, thanks!

The issue closed means resolved? I got the same error with raspberry 4 with nuget package: 0.1.0-20200807.1. Already run: sudo apt-get update && sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev but the error still persists.
