           Summary: Spurious / incorrect
                    AvoidMethodWithUnusedGenericTypeRule firing on
                    [CompilerGenerated] methods

           Version: 2.10.x

Demonstrates spurious AvoidMethodWithUnusedGenericTypeRule

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US)
AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.634.0 Safari/534.16

During the compilation of a class with generic methods, the compiler generates
several private generic methods that don't use the generic type parameter,
flagging them with [CompilerGenerated] in the assembly.

Gendarme flags these as defects, even though the code is not strictly
user-created.




Reproducible: Always

Steps to Reproduce:
1.Run Gendarme 2.10.x with ruleset EPS on attached assembly
2.
3.
Actual Results:  
2. AvoidMethodWithUnusedGenericTypeRule

Problem: One or more generic type parameters are not used in the formal
parameter list.
* Severity: Medium, Confidence: High
* Target:   System.Boolean
EPS.Diagnostics.LogHelper::<FindAndExecuteLoggingMethod>b__0(System.Reflection.MethodInfo)
* Source:   C:\Source\Common\source\EPS.Utility\Diagnostics\LogHelper.cs(≈32)
* Details:  Generic parameter 'T' is not used by the method parameters.

Solution: This prevents the compiler from inferring types when the method is
used which results in hard to use API definitions.

Expected Results:  
No defects listed.

[CompilerGenerated] methods should be ignored in this case.

Run using attached Xml rules file and ruleset EPS.
