How to add an assembly reference using CodeDOM?

This code (adapted from the examples in the docs) doesn't make complete
sense to me. I have it working, but I'm wondering why I need to declare an
assembly reference in 2 places. TIA.
Dave

CodeCompileUnit compileUnit = new CodeCompileUnit();
CodeNamespace myNamespace = new CodeNamespace("MyNamespace");
compileUnit.Namespaces.Add( myNamespace );
compileUnit.ReferencedAssemblies.Add(@"MyDLL.dll");//I declare an assembly
reference here first


myNamespace.Imports.Add( new CodeNamespaceImport("System") );
myNamespace.Imports.Add( new CodeNamespaceImport("MyOtherNamespace") );

[...]

ICodeCompiler compiler = provider.CreateCompiler();
CompilerParameters cp = new CompilerParameters(
new string[] {"System.dll",

"MyDLL.dll" //Now I still have to declare the assembly reference here too.
Why?

},

filepath.Substring(0, filepath.LastIndexOf(".") + 1)+"dll", false);
 
I think this is similar to VS.NET IDE does internally

You must be knowing that
1) You can add references to assemblies that you wish to use by "Add
Reference"
2) You can use any of the classes of "References" inside your classes
using "using" statement

So, while compiling, you need to provide, which DLLs you want to add to
current assembly in compilation.

Since, there is a possibility that
Although you have added a ref. to an external assembly, but you dont
want to it to be included as a part of your assembly

Correct me, anyone, if I am conceptually wrong

The "using" statements are taken care of by CodeNamespaceImport. However,
I'm speaking specifically about the need to declare assembly references
twice. I make one call with ReferencedAssemblies.Add. Then I am still
required (or I get errors) to define the assembly reference again as a
CompilerParameters parameter. That is the part that doesn't make sense to
me. It seems that ReferencedAssemblies.Add is not fully taking care of of
the task of defining a referenced assembly.

Hi. I'm wondering why you are working with CodeCompileUnit at all? Do you
have source code you are trying to compile or what?

If you have source code to work with then you would create the Compiler
object, add your CompilerParameters object, add your ReferencedAssemblies
and call CompileAssemblyFromSource() to compiler. In this situation there
is only one time you need to add references.
