DXCore Components – IssueProvider

December 2nd, 2010

The IssueProvider component represents a particular code issue check provider, which verifies the source code. This component is a part of the Code Issues Analysis Engine from the CodeRush. The newly created provider will be automatically registered once DXCore/CodeRush is loaded. You should be able to see it appear on the Editor | Code Analysis | Catalog options page in the Options Dialog.

You can drop the IssueProvider control onto your plug-in design surface from the “DXCore: Extensions & Providers” category of Visual Studio Toolbox:

Here’s the Properties window, containing available properties, their categories and default values:

and the Events list:

DXCore IssueProvider events

The IssueProvider component is located in the “DevExpress.CodeRush. Core” assembly. It is derived from the “CodeIssueProvider” base type from the same assembly. The base type is actually an old name of the component, later it was renamed into simple IssueProvider. The original base type is the ProviderBase type, which is a base type for all provider components (CodeProvider, NavigationProvider, CodeMetricProvider, StringProvider, etc):

ProviderName Name of this provider.
Register If true, this extension will be available to the DXCore – otherwise, it’ll be hidden.


Event name


CheckCodeIssues Handle this event to process a file and search for code issues. Use the Scope property of the passed-in event args (Scope usually points to an ISourceFile) to search that scope for issues.
LanguageSupported Handle this optional event if you want to restrict your code issue to one or more programming languages. If you do not handle this event, your code issue provider will be available in all programming languages.

Here’s a list of methods for using of this control:



GetCodeIssues Returns code issues enumerable for the given scope.
IsLanguageSupported Returns true if this code issue is available in the given language.
