The assembly title is a friendly name, which can include spaces.

In Windows Vista, the information specified for this attribute appears on the Details tab of the Windows File Properties dialog box for the assembly. The property name is File description. In Windows XP, this information appears on the Version tab of the Windows File Properties dialog box.

The following example shows how to add attributes, including the AssemblyTitleAttribute attribute, to a dynamic assembly. The example saves the assembly to disk, and the attribute value can be viewed by using the Windows File Properties dialog box.

using namespace System;
using namespace System::Reflection;
using namespace System::Reflection::Emit;


/*
// Create the callee transient dynamic assembly.
static Type^ CreateAssembly( AppDomain^ myDomain )
{
   AssemblyName^ myAssemblyName = gcnew AssemblyName;
   myAssemblyName->Name = "MyEmittedAssembly";

   // Set Company Attribute to the assembly.
   Type^ companyAttribute = AssemblyCompanyAttribute::typeid;
   array<Type^>^types1 = {String::typeid};
   ConstructorInfo^ myConstructorInfo1 = companyAttribute->GetConstructor( types1 );
   array<Object^>^obj1 = {"Microsoft Corporation"};
   CustomAttributeBuilder^ attributeBuilder1 = gcnew CustomAttributeBuilder( myConstructorInfo1,obj1 );
   myAssembly->SetCustomAttribute( attributeBuilder1 );

   // Set Copyright Attribute to the assembly.
   Type^ copyrightAttribute = AssemblyCopyrightAttribute::typeid;
   array<Type^>^types2 = {String::typeid};
   ConstructorInfo^ myConstructorInfo2 = copyrightAttribute->GetConstructor( types2 );
   array<Object^>^obj2 = {"@Copyright Microsoft Corp. 1990-2001"};
   CustomAttributeBuilder^ attributeBuilder2 = gcnew CustomAttributeBuilder( myConstructorInfo2,obj2 );
   myAssembly->SetCustomAttribute( attributeBuilder2 );
   ModuleBuilder^ myModule = myAssembly->DefineDynamicModule( "EmittedModule", "EmittedModule.mod" );

   // Define a public class named S"HelloWorld" in the assembly.
   TypeBuilder^ helloWorldClass = myModule->DefineType( "HelloWorld", TypeAttributes::Public );

   // Define the Display method.
