Hi,

Before we get started, my thanks to the UltiDev team for what is a very impressive offering - I'm using Cassini as I try to learn ASP.Net, and I think it's great... I'm certainly making my colleagues (I work in an Application development team) aware of it!

I'm working with SharpDevelop and Cassini, and writing a little app for internal consumption on my employer's LAN. One of my pages however keeps falling over because I have of a problem with how I have defined some properties on a user control...

Basically, I've taken advantage of a more concise way of declaring properties in C#, and declared a number of properties on my usercontrol as follows:

public string BeginParen{get; set;}
public string EndParen{get; set;}
public string OriginalText{get; set;}
public string TextDelimiter{get; set;}

When I view a page using this user control, the page crashes, and I get the exception detailed below in red...

Now, SharpDevelop is happy to compile the class (which tells me SharpDevelop is compiling as 3.5), but the error below would seem to suggest that Cassini is using the 2005 framework to compile the class when servicing the page request...

Simple questions then really - is this merely a config I've missed when setting up Cassini?

If not, and cassini always uses the 2005 compiler, can I still use 3.5 features like LINQ?

Martin.

Ps. In the mean time, I'm going to continue to use this great little server by simply writing my property declarations 2005 style...


Cheers!

Hello, Martin.

Thank you very much for using UltiDev Cassini and for such a great feedback.

Property declaration without actually implementing get/set accessors is valid in .NET 2.0 and they indicate that the class containing them is supposed to be abstract. This means that SharpDevelop may still be compiling your site as ASP.NET 2.0.

Since we don't use SharpDevelop in-house, we conducted a small experiment of creating a web site in VS 2005/.NET 2.0, and then converting it into ASP.NET 3.5. We found that the only change that occurred when we used Visual Studio 2008 to convert the site was a heavy modification to the web.config file.

To test whether the web site will be working in UltiDev Cassini after conversion to 3.5, we used C# 3.0 feature called lambda-expression along with TimeZoneInfo class introduced in Framework 3.5 and not present in 2.0. It worked like a charm, so we are pretty confident that if you use JIT compilation - as in case with Cassini and Web Site project type, you simply need proper settings in web.config. If SharpDevelop allows to specify target framework version and pre-compile the solution, like Web Application project type (which is different from Web Site type), then you need to adjust both web.config and SharpDevelop settings.

Below are three files that comprise our simple 3.5 web site that ran under Cassini successfully:

Default.aspx

Thanks for taking the time to investigate this...

I'm going to investigate the possibility that the assembly produced by SharpDevelop has been produced using the 2005 compiler. Primarily I work as a Windows Application developer, and I have encountered a similar issue using SharpDevelop with WinForms in the past. I dismissed it in this case because I didn't think the {get; set;} was legal in 2005 - so thanks for the correction on that...

I think I'm going to install FileMon, run the compilation again, and see which compiler is being used.

Once again, thanks for your help and support. You've far exceeded my expectations.

Martin.

I'll certainly do that...

Running process monitor didn't actually tell me a whole lot when SharpDevelop was compiling the web application - I did get some reports of it looking for 3.5 stuff and not finding it, but no reports of it actually using the 2.0 stuff...

I will keep looking, and will post details when I have them.
