'vb.net NAudio.dll - Type 'AudioFileReader' is not defined

(Visual Studio 2019)

It seems I have run into a snag.
My sample code is this.

Imports NAudio.Wave
Partial Class _Default
    Inherits System.Web.UI.Page
        Dim filename As String
        filename = "G:\VS_Lessons\Media\Read\01. Got to Choose.mp3
        Dim reader As New AudioFileReader(filename)
        Dim duration As String = reader.TotalTime.ToString("mm\:ss")
        reader.Dispose()
        Label1.Text = duration
    End Sub
End Class

This only happens when I am running the site LIVE and NOT from VS.
Running it through VS, it works as it supposed to.
Running it from a live URL it gives the following error.

Type 'AudioFileReader' is not defined

On this line 

Dim reader As New AudioFileReader(filename)

Now, I tried to register the NAudio.dll using. (The NAudio.dll file is in the BIN folder of the website)

gacutil -i NAudio.dll

However, I get the following line 

Failure adding assembly to the cache: Attempt to install an assembly without a strong name

I followed the steps in this article here How to add Strong Name to an existing DLL and install to the GAC

But I get a FAILURE when trying to create the DLL file on STEP 5. (Maybe I am doing it wrong because I am not the owner of the file. Not really sure, this is the first time I have ever done anything like this and was trying everything I could find online)

Any assistance on this would be mighty grateful.

Solution 1:[1]

The website has to be converted into an Application.
IIS | Web Site |
Right-click on the web site name or sub-folder name
And choose [Convert to Application]
Run the script, and it works.

Now, I have to do this on the live site, but first, I will do the local site, as it runs the same script, and I will get all the bugs out of it, then I can do the LIVE IIS site.

It Could Be Due To Partial Class Instead Of Public Class. Or You Haven't Downloaded Genuine DLL Version Of NAudio.

If Its Problem 1 ( Due To Use Of Partial Class ) Then Change To Public Class

If Its Problem 2 ( Use Of Non-Genuine NAudio DLL ) Then Download NAudio From Here

If Problem Still Persists, Then It Would Be For Windows Form Application.
