Code Analysis for Managed Code Warnings

The Managed Code Analysis tool provides warnings that indicate rule violations in managed code libraries. The warnings are organized into rule areas such as design, localization, performance, and security. Each warning signifies a violation of a Managed Code Analysis rule. This section provides in-depth discussions and examples for each Managed Code Analysis warning.

The following table shows the type of information that is provided for each warning.

Item	Description
Type	The TypeName for the rule.
CheckId	The unique identifier for the rule. CheckId and Category are used for in-source suppression of a warning.
Category	The category of the warning.
Breaking Change	Whether the fix for a violation of the rule is a breaking change. Breaking change means that an assembly that has a dependency on the target that caused the violation will not recompile with the new fixed version or might fail at run time because of the change. When multiple fixes are available and at least one fix is a breaking change and one fix is not, both 'Breaking' and 'Non Breaking' are specified.
Cause	The specific managed code that causes the rule to generate a warning.
Description	Discusses the issues that are behind the warning.
How to Fix Violations	Explains how to change the source code to satisfy the rule and prevent it from generating a warning.
When to Suppress Warnings	Describes when it is safe to suppress a warning from the rule.
Example Code	Examples that violate the rule and corrected examples that satisfy the rule.
Related Warnings	Related warnings.
