The Microsoft Mixed Minimum Rules focus on the most critical problems in C++ projects that support the Common Language Runtime, including potential security holes and application crashes.

Include this rule set in any custom rule set you create for your C++ projects that support the Common Language Runtime.

C28203 Ambiguous reference to class member.
C28205 _Success_ or _On_failure_ used in an illegal context

C28210 Annotations for the __on_failure context must not be in explicit pre context
C28211 Static context name expected for SAL_context
C28212 Pointer expression expected for annotation
C28213 The _Use_decl_annotations_ annotation must be used to reference, without modification, a prior declaration.
C28214 Attribute parameter names must be p1...p9
C28215 The typefix cannot be applied to a parameter that already has a typefix
C28216 The checkReturn annotation only applies to postconditions for the specific function parameter.
C28217 For function, the number of parameters to annotation does not match that found at file
C28218 For function parameter, the annotation's parameter does not match that found at file
C28219 Member of enumeration expected for annotation the parameter in the annotation
C28220 Integer expression expected for annotation the parameter in the annotation
C28221 String expression expected for the parameter in the annotation
C28222 __yes, __no, or __maybe expected for annotation
C28223 Did not find expected Token/identifier for annotation, parameter
C28224 Annotation requires parameters
C28225 Did not find the correct number of required parameters in annotation
C28226 Annotation cannot also be a PrimOp (in current declaration)

C28231 Annotation is only valid on array
C28232 pre, post, or deref not applied to any annotation
C28233 pre, post, or deref applied to a block
C28234 __at expression does not apply to current function
C28235 The function cannot stand alone as an annotation
C28236 The annotation cannot be used in an expression
C28237 The annotation on parameter is no longer supported
C28238 The annotation on parameter has more than one of value, stringValue, and longValue. Use paramn=xxx
C28239 The annotation on parameter has both value, stringValue, or longValue; and paramn=xxx. Use only paramn=xxx
C28240 The annotation on parameter has param2 but no param1
C28241 The annotation for function on parameter is not recognized
C28243 The annotation for function on parameter requires more dereferences than the actual type annotated allows
C28245 The annotation for function annotates 'this' on a non-member-function
C28246 The parameter annotation for function does not match the type of the parameter
C28250 Inconsistent annotation for function: the prior instance has an error.
C28251 Inconsistent annotation for function: this instance has an error.
C28252 Inconsistent annotation for function: parameter has another annotations on this instance.
C28253 Inconsistent annotation for function: parameter has another annotations on this instance.
C28254 dynamic_cast<>() is not supported in annotations
C28262 A syntax error in the annotation was found in function, for annotation
C28263 A syntax error in a conditional annotation was found for Intrinsic annotation
C28267 A syntax error in the annotations was found annotation in the function.
C28272 The annotation for function, parameter when examining is inconsistent with the function declaration
C28273 For function, the clues are inconsistent with the function declaration

C28287 For function, syntax Error in _At_() annotation (unrecognized parameter name)
C28288 For function, syntax Error in _At_() annotation (invalid parameter name)
C28289 For function: ReadableTo or WritableTo did not have a limit-spec as a parameter
C28290 the annotation for function contains more Externals than the actual number of parameters
C28291 post null/notnull at deref level 0 is meaningless for function.
C28300 Expression operands of incompatible types for operator
C28301 No annotations for first declaration of function.
C28302 An extra _Deref_ operator was found on annotation.
C28303 An ambiguous _Deref_ operator was found on annotation.
C28304 An improperly placed _Notref_ operator was found applied to token.
C28305 An error while parsing a token was discovered.
C28350 The annotation describes a situation that is not conditionally applicable.
C28351 The annotation describes where a dynamic value (a variable) cannot be used in the condition.
