Hardware & OS: Raspberry pi (Model B) & Soft-float Debian “wheezy”
Ok first thing I did was do a ‘mono-complete’ the install went smoothly. I ran some test and it worked great. the mono version was 2.10.8.x. I ran a simple ASP.net (NOT MVC) in XSP (& mono-fastcgi-server4) and it worked too. Then I tried a more complex version with a database (system.data.sqlite) that one did not go smooth but i figured my way out of that one.
So now I tried one version with sqlite + entity framework and shockingly (to me) it did not work. I tried so many different things. I couldn’t figure it out. So I started looking on the web what could be possibly be wrong I realised that entity framework was added to mono in the latest (BETA, 3.0.1) version. this was version 3.0.1 So I downloaded this version and installed. it took forever and ever to install.

But it installed. I did some test(in csharp interactive compiler) and it seemed to be OK. While it was building/compiling/installing I did see plenty of warnings. I don’t know if this is normal. Else i would expect an error and it has to immediately stop.
Ok Here is my problem now:
I tried to run a simple website and see this in the browser:

Version information: Mono Runtime Version: 2.10.8.1 (Debian 2.10.8.1-5); ASP.NET Version: 4.0.30319.1
if you noticed at the bottom the error you can clearly see ‘Version information: Mono Runtime Version: 2.10.8.1 (Debian 2.10.8.1-5); ASP.NET Version: 4.0.30319.1’ I was expecting to see another runtime version.
So where do I proceed from here? Is this a bug? Did the install go wrong? another xsp version? Should I install again? can I fix this? It could be anything so let me ask before i waste a lot of time and effort into it.
I wrote this post and found out the problem immediately after. It was indeed something wrong with XSP4 (or mono-fastcgi-server4). I installed mono 3.0.1 under the assumption that it would install the latest xsp. But that was not the case. So I downloaded the latest version from github. And my basic website was working again. But my website with entity framework is still not working didn’t get the time to work that out yet. I was going to do that before I would report my findings here.
