C++/CLI is a set of C++ language extensions by Microsoft designed for easy interoperability between managed and native code. It includes generics, value and ref classes, handles, tracking references, interfaces, and other syntactic additions.
Besides the main set of code analysis, navigation and search, coding assistance, and other features you’re used to with C++, JetBrains Rider provides additional support for C++/CLI-specific cases.
Search and navigation
Since C++/CLI is a bridge between the languages, JetBrains Rider provides cross-language navigation features to improve interoperability:
Find Usages and Go To Declaration work between C++/CLI and C#.
When looking for derived symbols from C++/CLI code, JetBrains Rider will find symbols in C# code in addition to symbols in C++/CLI.
Go to Base Symbols and Go to Derived Symbols work on imported CLR entities.
Go to Derived Symbols also works for
set functions inside C++/CLI properties and
remove functions inside C++/CLI events.
JetBrains Rider includes a set of inspections for C++/CLI-specific language constructions:
You’ll get a warning if there is missing
virtualspecifier for an interface member, or it does not have
JetBrains Rider inspects the way you allocate memory and suggests a quick-fix to replace
newwhen the target type is not valid. It also works for replacing
JetBrains Rider warns you when you try to use the C++
finalspecifier on a managed class or interface, with a quick-fix to make it
There are also a few helpful quick-fixes for C++/CLI. For example, the
safe_cast operator in C++/CLI is especially useful when downcasting from a base class to a derived one:
safe_cast performs a dynamic check and throws
InvalidCastException if the conversion fails. You can use a quick-fix to convert a C-style cast to a
In addition to parameter name and type name hints, JetBrains Rider provides type conversion hints for C++/CLI boxing conversions, which result in an allocation on the managed heap. Such hints for standard conversions are disabled by default, but you can enable them on the page of JetBrains Rider settings Ctrl+Alt+S.
Additional formatting settings allow you to configure style for C++/CLI generic constraints: select the preferred indentation, add spaces where needed, and force line breaks ().
Some C++ postfix templates are specially designed to produce C++/CLI code when invoked in its context.
.gcnewto produce instantiation expression for a type.
