Justin/Su,

I am getting same System.XML error (Error CS0234: The type or namespace name ‘Xml’ does not exist in the namespace ‘System’ (are you missing an assembly reference?)
, it recognizes System.IO, but cannot recognize System.XML.

I am working on 0.6.7 opensim. Any ideas? Please Help!!!

Regards,
Dimple

@su - Not to my knowledge. But I’d be happy to take a look at your code if you e-mail me your OpenSim.ini and the exact text of what you’re trying to run.

@justincc- yes i was using the full names. Sine my own code was not working, I just copy-pasted your example code. Is there anything else we have to add to your code?

@su - I just tried the script I have in the blogpost on the most uptodate OpenSim (97c18caa766e2dd72b152b78827ef554f2054f8c, 22nd Sept 2009) and it works fine (and this under XEngine). Are you using the full names of types (e.g. System.Xml.XmlTextReader rather than just XmlTextReader)? Unfortunately, C#’s normal using statements will not work with OpenSim’s C# ’scripts’.

@su - Hmm, thanks for the data, I’ll go back and give this a test when I can. It sounds a little strange to me.

i reported a bug to mantis (http://opensimulator.org/mantis/view.php?id=4137) and according to the response I got from Melanie, the allowed references are hardcoded into the compiler. But since it is working for you, does it mean that you can change the compiler settings to include the references needed?

I was able to resolve the second error. problem there was with the Script Engine. In my case, when the script engine was “XEngine”, it did not work. Then I changed it to “ScriptEngine.DotNetEngine” and now the compiler detects C#. but the error with the compiler not being able to detect System.Xml is still there

Hi justincc,
I installed Opensim in my machine in standalone mode and set
AllowedCompilers = lsl,cs

I am also getting the same error that Robert got: “Primitive: Error compiling script:
The compiler for language “cs” is not in list of allowed compilers. Script will not be executed!”

I am using OpenSimulator Server 0.6.6.
Were you being able to figure out the reason for this?

Rgds,
Su

I’m also getting the same error as Cliff and Takis. Strange that it recognizes System.IO, but cannot recognize System.XML. So anyone found the reason for this?
@justincc- is there any place where we can add additional assemblies to OpenSim .NET environment?

Rgds,
Su

Hi justincc
I was testing with MonoDev 2.0 by the way. I am continuing to write scripts in C#, but have met another imponderable. Do you happen to know how to switch states - the statement ’state newstate’ doesn’t have any very obvious equivalent in C# - presumably there is a function call of some sort? or do we have to do the complete C# event handler setup process?
