[Mono-list] missing assembly reference?

[Jaroslaw Kowalski]

Try passing -r parameter(s) to mcs:

mcs -r:System.Web.dll -r:System.Web.Services.dll  hello.cs

This tells the compiler to look for additional classes in the specified
assemblies.
Be aware that assemblies != namespaces. For example you have assembly named
"mscorlib" that contains namespaces like "System", "System.IO",
"System.Net".

Also, CSC.EXE on windows references some assemblies by default, they are:

Accessibility.dll
Microsoft.Vsa.dll
System.Configuration.Install.dll
System.Data.dll
System.Design.dll
System.DirectoryServices.dll
System.dll
System.Drawing.Design.dll
System.Drawing.dll
System.EnterpriseServices.dll
System.Management.dll
System.Messaging.dll
System.Runtime.Remoting.dll
System.Runtime.Serialization.Formatters.Soap.dll
System.Security.dll
System.ServiceProcess.dll
System.Web.dll
System.Web.Mobile.dll
System.Web.RegularExpressions.dll
System.Web.Services.dll
System.Windows.Forms.Dll
System.XML.dll

so when using CSC you don't need to specify references for them and they are
automatically available for "using". When using MCS you have to reference
assemblies by hand.
