Electron 42.0.0+ Not Supported

[AeonSake]

Newer Electron versions starting with 42.0.0 no longer work with Electron.NET. I tested the most recent version (42.3.3) which doesn't work, as well as the last major version (41.7.1) which still works. I also tried upgrading to the latest electron-builder version (26.14.0) without luck.

• NuGet Version: 0.5.0
• Electron Version: 42.3.3 (also tested with 42.0.0)
• Electron Builder Version: 26.8.1
• Framework: net10.0
• Target: linux-arm64
• IDE: Visual Studio 18.6.2

Given the log entries, it seems like some parts of the build pipeline that produces the .electron folder are broken.

Steps to reproduce:

• Create a new blazor web app (dotnet new blazor)
• Add the ElectronNET.Core and ElectronNET.Core.AspNet NuGet packages version 0.5.0
• Add UseElectron() to the builder, etc. (follow getting started from Wiki)
• Add the following to the csproj file:

<PropertyGroup Label="ElectronNetCommon">
  <ElectronVersion>42.0.0</ElectronVersion>
  <ElectronBuilderVersion>26.8.1</ElectronBuilderVersion>
</PropertyGroup>

The strange part is, that the folder does exist and was updated with the (presumably) correct content. However, the file under .electron\node_modules\electron\dist\electron does not (dist folder is missing). It looks like electron 42.0.0 and later no longer ship a post-install script to fetch the binaries as part of the npm package; users need to fetch them via @electron/get instead.

I think this makes sense as postinstall scripts will more and more fade out (due to security problems).

We will need to address this. Thanks for reporting. I will try to find some time on the weekend to look at this.

Landed in preview - will be published with 0.5.1.
