Description of Problem:
If you are compiling C# source code using new
CSharpCodeProvider().CreateCompiler().CompileAssemblyFromSource(...) and
you set the parameter GenerateInMemory to true and OutputAssembly parameter
is empty the compiler will fail.


Steps to reproduce the problem:
1. Compile attached sample
2. Run

Actual Results:
using System; namespace MyNamespace {
        class Message
        {
                public void MSGOutput()
                {
                        Console.WriteLine("Hello world");
                }
        }
}
With file as output assembly
Hello world
Without file as output assembly

Unhandled Exception: System.ArgumentException: Name is empty 
in <0x004d7> System.IO.FileStream:.ctor (System.String name, FileMode mode,
FileAccess access, FileShare share, Int32 bufferSize, Boolean isAsync,
Boolean anonymous)

FileAccess access, FileShare share)

(System.CodeDom.Compiler.CompilerParameters options, System.String source) 
in <0x0035f> CompilerTestEx.CompilerTest:Main (System.String[] args) 

Expected Results:
using System;
namespace MyNamespace
{
        class Message
        {
                public void MSGOutput()
                {
                        Console.WriteLine("Hello world");
                }
        }
}
With file as output assembly
Hello world
Without file as output assembly
Hello world


How often does this happen? 
Always

Additional Information:
There should be created a temporary assembly file internally for this case.

The specific issue you reported (for the CSharpCodeCompiler) is now 
fixed in SVN.

I'll leave the bug report open until I've verified whether we need a 
similar fix for the VBCodeCompiler.  I'm pretty sure we do.

VBCodeCompiler is now fixed too.
