Hi all,

I need your support to make ajax application on mono.
Here is my configuration :

Telerik RadControls .NET 2.0 Q1 2009
Mono 2.4 on vmware 2.4.2.3 Suse Linux with Firefox

I try to run one of Telerik demos (AjaxifyTimer) on mono but Ajax callbacks are not performed and I've got the error in the Firefox console (or in IE console) :

    
            Error: [Exception... "'Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.  
        
            Details: Error parsing near '<!DOCTYPE html PUBLI'.' when calling method: [nsIDOMEventListener::handleEvent]"  nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)"  location: "<unknown>"  data: no]

I don't understand what is the mistake as I try to run your demo on my Mono, without changing anything in the code.
So is it a problem with mono configuration ?
Or in the Web.config ?
How do you do to make run your demos on your mono server ?
What are the requirements and configuration ?
Thanks for your help.

Hi Sunil,

This post is from almost a decade ago. There was, indeed, some effort into supporting the Mono implementation that existed at the time. In later years there was no demand for that and the Mono project itself was abandoned, and so we dropped the initiative and the Mono support. It seems that the Mono project may have been renewed, yet we do not support it anymore. Perhaps some (or even all) things will work, but we have not tested that and we cannot guarantee compatibility.

If you are looking into hosting a web app under Linux, I can suggest you take a look at .NET Core and its Linux support. We also offer controls for MVC Core (wrappers over the Kendo jQuery widgets), so you may find that useful as well.
