Why we use fxcop

Clicking on the Excluded button on top of the message pane will show you all the excluded messages. Double clicking on the message shows you again the "Message Details" dialog and the Notes tab allows you to view the notes you entered when marking the message as excluded. You can move a message back to the active list by right clicking on it and selecting "Mark as Active" from the popup menu. You can also do this by double clicking on the message and selecting the Unexclude button on the "Message Details" dialog.

You have two ways to remove a message from the Active list after you have resolved the issue. You can right click on the message and select "Mark as Absent" from the popup menu or you just run another analysis and FxCop detects that the issue has been resolved and moves it to the Absent list for you. Don't forget to recompile your code as FxCop doesn't look at the source code but rather the compiled assembly.

I consider it good practice to add some notes to the message after it has been moved to the Absent list. This provides a historical view and allows to go back and understand why you have made certain changes. Clicking on the Absent button on top of the message pane shows you all the resolved issues. Saving your FxCop project only saves active and excluded messages but not the Absent ones.

So if you want to keep a historical view go to menu "Project Options" and on the "Project Options" dialog, on the Standard tab, select the Absent checkbox in the "Save Messages" group. This changes the option only for the current project. Going to "Tools Settings" menu shows the Settings dialog. On the "Project defaults" tab, select the Absent checkbox under the "Save Messages" group. This setting takes then effect for all future FxCop projects you create.

I recommend keeping the historical view because I always find it useful to be able to go back and understand what has been changed on a project over time, especially if you suddenly run into un-explainable exceptions, crashes or other difficulties with your product.

This pane has two tabs. The properties tab shows information about the selected assembly, namespace, type, type member, group of rules, rule or message. We have covered that already in detail. The Output tab shows informational, warning and error messages generated by the rules. These messages only appear if the TraceGeneral trace-switch in the FxCop. Click on the menu "File Save Report As" and provide a name and location for the report.

The report allows you to drill down to all messages on the assembly level, type level and type member level. NET build my project, it also performs an FxCop analysis, which can be quite handy, as it:. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

One rule set enables all rules for the category, and one rule set honors the default severity and enablement settings for each rule in the category. The Microsoft. To make a rule set the active rule set for analysis in. Under Run this rule set, select Browse, and then select the desired rule set that you copied to the project directory or create a new set of rules.

To enable. You can add an. You can share an. Add a line to your. Reload the project. Point to note, we cannot configure legacy FxCop rules static code analysis FxCop by using an. Custom Analyzer Based On. Not all required coding standards by specific organization can be achieved with default rulesets.

We need to build custom rulesets to cater to our specific requirements. So, we take advantage of Roslyn. We use compiler APIs to write our own custom analyzers. The most important data structure which is exposed by the compiler APIs is syntax tree. Work space APIs provide access to the source code projects and documents in a solution and to their associated syntax trees, compilations and semantic models. It has an immutable snapshot of the projects and documents of a solution in visual studio.

It creates three projects under a single solution, one is major project to implement our custom analyzer code, second one is the project to implement tests and another one is setup project. These values will be displayed on the IDE when this custom rule is applied on code snippet.

And we need to include this Rule in immutable Array as shown below in the below screenshot. Then, register an action to be executed at completion of analysis of SyntaxNode with a proper kind Kind is an example of method declaration, property declaration and class declaration etc. We need to install the VSIX extension package of our custom code analyzer to the Visual Studio and then it will be available as code analysis rulesets for our project.

If the same rule is listed two or more times in a rule set with different severities, the compiler generates an error. If the same rule is listed two or more times in a rule set with the same severity, you may see the following warning in the Error List:. If the rule set includes a child rule set by using an Include tag, and the child and parent rule sets both list the same rule but with different severities, then the severity in the parent rule set takes precedence.

For example:. Build and fix or ignore warnings Once the ruleset files are configured using RulesSet option, the next step is to do a rebuild of the solution and fix or ignore any warnings that pop up. To disable the rule, follow the steps below. Under the code analyzer, find the rule you want to disable and right-click on it and set the Rule Set Severity to None. Now, finally we are going to use the sample project created to test the Code Quality using FxCop analyzer. In addition, FxCop analyzer violations also show up in the code editor as squiggles under the offending code.

In addition, StyleCop analyzer violations also show up in the code editor as squiggles under the offending code. In addition, Custom analyzer violations also show up in the code editor as squiggles under the offending code. It is a meta package of four other analyzer packages: Microsoft. For instance, implementing IDisposable properly and passing URIs instead of strings are both checked in this package. Analyzers: Full framework. Analyzers: This package provides some basic spell checking disabled by default.
