until link time. The resulting object files contain C Intermediate Language (CIL) code rather than machine-dependent assembly code. Then, when the linker (link.exe) is invoked, it sees that the object files contain CIL code and invokes the back end of the compiler, which in turn perfor...

ReSharper C++ assumes that each header file starts with an include guard or a#pragma oncedirective, and gets included at most once in any source file. Each successive include of the same header does not count towards its number of contributed lines, which means that sometimes you may encounter...
with a new compatibility mode option. Once turned on (project wide, or per file via the{$CROSSPLATFORM ON}or#pragma crossplatform ondirectives), it makes the compiler less strict about using platform-specific language syntaxes, and also emits helpful hints and warnings that give you heads up...
New pragma directive detect_mistmatch The pragma directivedetect_mismatchlets you put a tag in your files that is compared to other tags that have the same name. If there are multiple values for the same name, the linker issues an error. ...
