Because of this, there are some major syntactic changes, especially related to the elimination of ambiguous identifiers and the addition of .NET-specific features. </p><p>Many conflicting syntaxes, such as the multiple versions of operator <code class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><span class="k">new</span><span class="p">()</span></code> in MC++, have been split: in C++/CLI, .NET reference types are created with the new keyword <code class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><span class="n">gcnew</span></code> (i.e. <a href="/wiki/Garbage_collection_(computer_science)" title="Garbage collection (computer science)">garbage collected</a> new()).

In C++/CLI, however, the only type of pointer is the normal C++ pointer, while the .NET reference types are accessed through a "handle", with the new syntax <code class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><span class="n">ClassName</span><span class="o">^</span></code> (instead of <code class="mw-highlight mw-highlight-lang-cpp mw-content-ltr" dir="ltr"><span class="n">ClassName</span><span class="o">*</span></code>).

Every * becomes a ^, every & becomes an %, but the rest of the syntax is unchanged, except for an important addition: for .NET classes, operator overloading is possible not only for classes themselves, but also for references to those classes. This feature is necessary to give a ref class the semantics for operator overloading expected from .NET ref classes. (In reverse, this also means that for .NET framework ref classes, reference operator overloading often is implicitly implemented in C++/CLI.) </p><p>For example, comparing two distinct String references (String^) via the operator == will give true whenever the two strings are equal. The operator overloading is static, however.
