+Summary: CodeCompiler.CompileAssemblyFromSource fails with GenerateInMemory == true
+
+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.
