ASP.NET MVC Preview 5 on Mono

Question

Does anyone have any information about getting the current versions of ASP.NET MVC (Preview 5) working on Mono 2.0? There was info on the old versions (Preview 2, maybe Preview 3), but I've seen no details about making Preview 5 actually work.

The Mono Project Roadmap indicates ASP.NET 3.5 for Mono 2.4 (next year). Any ideas on how to get this useful before then?

More details: The basic MVC Preview 5 template seems to work, so long as I avoid the root directory. If I request the root, I get:

Server Error in '/' Application
The virtual path '' maps to another application.

Description: HTTP 500. Error processing request.

Stack Trace:

System.Web.HttpException: The virtual path '' maps to another application.

Answer 1

Well a potential is that RewritePath to / has some sort of bug, so just avoid that. Changing the RewritePath(Request.ApplicationPath) to:

HttpContext.Current.RewritePath("/Home/Index");

Seems to fix the problem, and at least the demo works so far.

Answer 2

Are you using Mono from svn or stable? What kind of webserver are you using? What kind of Operating system? Do you have rewrite rules in your web server?

I can run preview 4 in Linux with this in the page_load method in default.aspx.cs

HttpContext.Current.RewritePath(Request.ApplicationPath);
 ((IHttpHandler)new MvcHttpHandler()).ProcessRequest(HttpContext.Current);

I need that in windows sometimes too. I didn't test version 5 in Linux yet, so it might not work.

Does anyone care that using ASP.NET MVC on platforms other than Microsoft's (including Mono) is expressly forbidden by the license? To quote:

The Additional Use Rights extend only to the software or permitted derivative works that you create that run on a Microsoft Windows operating system product

"Additonal Use Rights" is defined in a section above as including just about anything beyond reading the code.

IANAL, but it seems to me that such a statement would be put in there precisely to prevent you from running MVC on Mono (at least at this time), especially when you consider that other pre-release components, like F#, don't have this restriction.

Now, maybe you really don't care about the license restriction, but you should at least know about it...

Answer 4

Now that Asp.net MVC 1.0 has been released - can anyone tell me if David's point still applies? There seems to be no mention of a restriction to Windows in the user agreement - and indeed the license cited in the link seems to relate to Pre-release software...

Answer 5

Asp.Net MVC 1.0 will work with the 2.4 branch of mono but you will still need to fix the RewritePath in page load of default.aspx.cs
