`UseElectron` Incorrectly Changes Host Configuration When `wwwroot` Directory Exists

[AeonSake]

The UseElectron method applied to a WebApplicationBuilder changes the host configuration (content root of WebHost) which is not allowed. This issue comes up whenever the wwwroot directory exists when the application is started; which is an issue when working with pre-/post-build actions that copy stuff into the wwwroot directory (e.g., copying assets or build artifacts from another stage).

Electron.NET/src/ElectronNET.AspNet/API/WebHostBuilderExtensions.cs

Lines 72 to 83 in c8268fa

	// check for the content folder if its exists in base director otherwise no need to include
	// It was used before because we are publishing the project which copies everything to bin folder and contentroot wwwroot was folder there.
	// now we have implemented the live reload if app is run using /watch then we need to use the default project path.
	if (Directory.Exists($"{AppDomain.CurrentDomain.BaseDirectory}\\wwwroot"))
	{
	builder = builder.UseContentRoot(AppDomain.CurrentDomain.BaseDirectory)
	.UseUrls("http://localhost:" + webPort);
	}
	else
	{
	builder = builder.UseUrls("http://localhost:" + webPort);
	}

The exception is thrown here:
https://github.com/dotnet/aspnetcore/blob/e0d31d9fb90de374424f555ab58e5bfec86d46e6/src/DefaultBuilder/src/ConfigureWebHostBuilder.cs#L64-L69

Call Stack:

ConfigureWebHostBuilder.UseSetting(string, string?)
HostingAbstractionsWebHostBuilderExtensions.UseContentRoot(this IWebHostBuilder, string)
WebHostBuilderExtensions.UseElectron(this IWebHostBuilder, string[], Func<Task>)
WebApplicationBuilderExtensions.UseElectron(this WebApplicationBuilder, string[], Func<Task>)

Steps to reproduce:

• Create a new Electron.NET project
• Build once (to create the Debug/Release paths)
• Create a folder called wwwroot in the build output directory (e.g., <app>/bin/Debug/net10.0/win-x64)
• Start the application in debug mode

I'm not sure whether this is also an issue for the final build/package but it is definitely a problem for debugging.

I am facing this exact issue. Everything worked with prototyping (ASP.Net Blazor Server ) but as soon as I added a sqlite db in wwwroot\data, I cant start the project anymore.
