ReportExecutionService Fails on 2016 - asp.net

Question

We copied an asp.net website from a 2008R2 Windows and SQL Server server to a Windows 2016 server with SQL Server 2016 and when we try to open the website from a browser it fails with the following error and stack trace.
Message: E:\shared\apps\RepairTrak\About.aspx.vb(19): error BC30002: Type 'ReportExecutionService' is not defined.
Stack Trace:

Below is the entire code-behind page named About.aspx that is throwing the error.
Imports Microsoft.Reporting.WebForms.Internal.Soap.ReportingServices2005.Execution
Partial Class About
Inherits Page
Private Sub About_Load(sender As Object, e As EventArgs) Handles Me.Load
Dim virtualFolderPath As String = "~/Photos/_Rotated/"
'Get information about the files in the specified folder
Dim strPhysicalPath As String = Server.MapPath(virtualFolderPath)
strPhysicalPath &= "IMG_061749.JPG"
'Get information about the image
'Dim currentImage As System.Drawing.Image = System.Drawing.Image.FromFile(strPhysicalPath)
ImageRounded.ImageUrl = strPhysicalPath
ImageThumb.ImageUrl = strPhysicalPath
' ReportExecution object prepare
Dim rs As New ReportExecutionService()
End Sub
End Class

Answer 1

Turns out I had to install the ReportViewer runtime exe on the new server.
