assembly cant access System.Xml

[Karl Hungus]

A cs file I compiled into an assembly dll is in my bin directory. In the cs
file I have a using statement for System.Xml
I compiled it using this command: csc /out:XmlContent.dll /t:library
XmlContent.cs

When I run my aspx page, which has a codebehind that instantiates the object
from in my assembly, I get the following error, anyone know why?

Hi Karl,
If you are building an assembly which references Microsoft's
System.Xml.dll you can specify the /reference:System.Xml.dll switch when
invoking CSC.exe to resolve the issue.The compiler will find the
System.Xml.dll in the directory which contains the CLR which the compiler
itself is using to produce the assembly.
Additionl info: But at runtime System.dll will be loaded from the GAC .So
we have 2 copies of Microsoft'a assembly files.
Hope this helps.

Hey Marshal,

Thanks for your reply. I tried that and it wasn't successful. I now believe
the problem is related to different framework versions. Locally I have v1.1
and on my server its v1.0

Im currently searching for ways to deal with this. Please let me know if you
have any solution.

Thanks,
Karl

Hi Karl,
If you are running v 1.0 and 1.1 side by side read the link below :
http://www.asp.net/faq/SideBySide.aspx

Once version 1.1 of the .NET Framework is installed,by default
all of the web applications will use
v 1.1 eventhough 1.0 exists.
It is useful for you to know about response files to make
your compilation easier.A response file is a text file
that contains a set of compiler command-line switches.Here is a link on
MSDN for that..

http://msdn.microsoft.com/library/d...n-us/cscomp/html/vcerrspecifyresponsefile.asp

You might consider using Visual Studio .NET which will do
all the compilation for you.
It will increase your productivity dramatically in so many ways.

Hope this helps,
