Hello, I downloaded this just to see how Electron worked: https://github.com/ElectronNET/electron.net-musicplayer-sample
I could compile and run the program without any issues, so I wanted to create my own project.

I am using Visual Studio 2019, I choosed "ASP.NET Core Web Application" and then installed the Electron.API NuGet (Version 7.30.2) and then ran electronize init.

But the Issue I am having is that when running electronize start it creates a Window for me but it is just blank, none of my HTML shows up.

This is how my project looks like:

The console outputs the following:

And the developer console on the Electron app outputs the following:

security-warnings.ts:179 Electron Security Warning (Insecure Content-Security-Policy) This renderer process has either no Content Security
    Policy set or a policy with "unsafe-eval" enabled. This exposes users of
    this app to unnecessary security risks.

For more information and help, consult
https://electronjs.org/docs/tutorial/security.
This warning will not show up
once the app is packaged.
(anonymous) @ security-warnings.ts:179
localhost/:1 Failed to load resource: the server responded with a status of 404 (Not Found)

My Startup.cs
https://pastebin.com/NmKzhnHc

And my Program.cs
https://pastebin.com/XHXVdGF7

My .csproj file looks identical to the musicplayer sample linked above.
To my understanding it seems like the Electron app has trouble finding the .cshtml, but I might be wrong on that subject.
Any ideas why the application just show up a white background?
