ASHX file Parser error - could not create type

I got a sample application to install on IIS from a vendor that I am testing for making barcodes.

The aspx pages work fine, but when the aspx page calls the ashx page, I get the error below:

Server Error in '/BarcodeSample' Application.

Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not create type 'TECIT.OnlineBarcodes.BarcodeHandler'.

Source Error:

Line 1: <%@ WebHandler Language="C#" CodeBehind="BarcodeHandler.ashx.cs" Class="TECIT.OnlineBarcodes.BarcodeHandler" %>

Source File: /BarcodeSample/BarcodeHandler.ashx Line: 1

-------------------------------------------------------------------------------- Version Information: Microsoft .NET Framework Version:2.0.50727.3634; ASP.NET Version:2.0.50727.3634

Why is this happening? How can I get this ashx file to work?

In Visual Studio, click on your generic handler in Solution Explorer, then press F4 for "Properties". Make sure your build action is "compile", not just "content".

I renamed my handler through the solution explorer.

VS2017 suggested changeing the name only in .cs file, and left the class attribute in the ashx file incorrect.

A simple workaround that I found works:

  • Put the .ashx.cs code after the first line of the .ashx file
  • Remove the CodeBehind attribute on the first line of the .ashx file
  • Remove the Code behind file

Check the full name of the class starting from the namespace (if used). I had the same issue and it was fixed after changing the class name like this:

<%@ WebHandler Language="C#" Class="Namespace.ClassName" %>

instead of this:

<%@ WebHandler Language="C#" Class="ClassName" %>

I had an issue with the naming of the namespace, so I had to edit the example.ashx file (not the example.ashx.cs) and change the namespace name there.

Add below tag

<%@ Assembly  Name="YourNameSpace.YourHandlerClass, Version=1.0.0.0, Culture=neutral, PublicKeyToken=90e3045b123af1c3" %>

above your WebHandler tag

<%@ WebHandler Language="C#" CodeBehind="BarcodeHandler.ashx.cs" Class="TECIT.OnlineBarcodes.BarcodeHandler" %>
