Your code is running on a web server. When you are automating office, it's happening *on the server*. When you hit a line of code like 'WordApp.Visible = true;', that's never going to make it visible to the user in their web browser.

The reason it works in visual studio is because you're running it on your computer, where you are the server & the client - this is not something that will work in a deployed solution

You need to rethink how you are going to achieve this.

For starters, office automation on a web server really isn't recommended.

Is Office correcrly installed on the web server? Does the account running the web process have permissions to all the relevant locations. Any messages in event viewer?

Why not try wrapping your statement in a try-catch block, and then log the Exception to a file.

C#

try
{
    Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application();
 
    var path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "New" + ".docx");
 
    object fileName = path;
    object readOnly = false;
    object startIndex = 0;
    object isVisible = true;
    object missing = System.Reflection.Missing.Value;
 
    // WHY make an application visible on the server?????!
    WordApp.Visible = true;
 
    Microsoft.Office.Interop.Word.Document aDoc = WordApp.Documents.Add();
}
catch (Exception ex)
{
    // However you log errors
    MyLogger.Log(ex.Message);
}

But really, you shouldn't be doing this. You do understand this is happening on the server, right? It's not going to show anything on the client.
