Question

I created a new .net 8.0 winforms project in vs2022, it includes the latest webview2 nuget package.
This is the full project code:

myawesomeprogram.cs

namespace myawesomenamespace
{
  internal static class myawesomeprogram
  {
    [STAThread]
    static void Main()
    {
      ApplicationConfiguration.Initialize();
      Application.Run(new myawesomeform());
    }
  }
}

myawesomeform.designer.cs

namespace myawesomenamespace
{
  partial class myawesomeform
  {
    private System.ComponentModel.IContainer components = null;

    protected override void Dispose(bool disposing)
    {
      if (disposing && (components != null))
      {
        components.Dispose();
      }
      base.Dispose(disposing);
    }

    private void InitializeComponent()
    {
      myawesomewebview = new Microsoft.Web.WebView2.WinForms.WebView2();          
      ((System.ComponentModel.ISupportInitialize)myawesomewebview).BeginInit();
      SuspendLayout();

      myawesomewebview.AllowExternalDrop = true;
      myawesomewebview.CreationProperties = null;
      myawesomewebview.DefaultBackgroundColor = Color.White;
      myawesomewebview.Dock = DockStyle.Fill;
      myawesomewebview.Location = new Point(0, 0);
      myawesomewebview.Name = "myawesomewebview";
      myawesomewebview.Size = new Size(800, 450);
      myawesomewebview.TabIndex = 4;
      myawesomewebview.ZoomFactor = 1D;

      AutoScaleDimensions = new SizeF(7F, 15F);
      AutoScaleMode = AutoScaleMode.Font;
      ClientSize = new Size(800, 450);
      Controls.Add(myawesomewebview);
      Name = "myawesomeform";
      Text = "myawesomeform";
      WindowState = FormWindowState.Maximized;
      Load += myawesomeform_Load;
      ((System.ComponentModel.ISupportInitialize)myawesomewebview).EndInit();
      ResumeLayout(false);
    }

    private Microsoft.Web.WebView2.WinForms.WebView2 myawesomewebview;
  }
}

myawesomeform.cs

using Microsoft.Web.WebView2.Core;

namespace myawesomenamespace
{
  public partial class myawesomeform : Form
  {
    private Random? myawesomerandom;

    public myawesomeform()
    {
      InitializeComponent();
    }

    private async void myawesomeform_Load(object sender, EventArgs e)
    {
      CoreWebView2Environment? myawesomeenvironment = await CoreWebView2Environment.CreateAsync();
      await myawesomewebview.EnsureCoreWebView2Async(myawesomeenvironment);

      myawesomerandom = new Random();
      await Task.Delay(myawesomerandom.Next(1000, 2000));
      myawesomewebview.Source = new Uri("http://lixxx.co.uk");
      await Task.Delay(myawesomerandom.Next(1000, 2000));
      myawesomewebview.Source = new Uri("http://lmfgtfy.co.uk");
    }
  }
}

It runs on my development machine perfectly well.

I configured a publish profile with a release configuration, a .net 8.0 windows target framework, a win x64 target runtime, a self contained deployment mode using the single file and ready to run compilation options.

The published .exe file, in its published directory, runs correctly.

When I cut and paste the entire published directory onto a 64 bit AMD server, running windows server 2022 and run the .exe, the application loads and immediately displays an unhandled error exception dialogue with the exception text:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************

The application had a requirement to write to a text file, but I have since deleted it from the latest builds.

The server has the .net 8.0 hosting bundle and the .net 8.0 x64 desktop runtime installed.

Why does my .net 8.0 winforms app throw a ‘System.IO.FileNotFoundException: The system cannot find the file specified’ exception on the target server?
