Code Analysis in XAML

The key features of ReSharper's code analysis are also supported in XAML. You can find the detailed information on these features in the corresponding topics of the Code Analysis section. In the main topic of the section, you can also find the feature matrix and check what exactly is supported in XAML.

In this topic, you can find some examples of using code analysis features in XAML:

Code inspection

ReSharper detects various problems in XAML files, such as unresolved symbols, incorrect document structure, unused import directives, etc. Whenever a problem is encountered, ReSharper highlights it and displays some description in a tooltip. For more information about ways to find out why the code is highlighted, see Finding Out What is Wrong with Your Code.

In the example below, ReSharper warns that the namespace alias is not used inside the current file and highlights it in grey:

ReSharper_by_Language__XAML__Code_Highlighting_01

In the example below, ReSharper highlights a problem with resolving a method inside an event subscription:
ReSharper_by_Language__XAML__Code_Highlighting_02

Solution-wide analysis

ReSharper does not only analyze errors in the current XAML file, but also inspects all files in the whole solution and shows the results of the analysis in the Errors in Solution window. It takes dependencies between files into account and updates the results when you change code.

For more information, see Solution-Wide Analysis.

Examples of quick-fixes

Make field private
To change visibility of a field declared in XAML, use the appropriate quick-fix.

ReSharper_by_Language__XAML__Context_Actions__make_private_01

After applying the quick-fix, the value of FieldModifier is changed to private.
ReSharper_by_Language__XAML__Context_Actions__make_private_02

Remove redundant namespace alias
To remove a redundant namespace alias, use the appropriate quick-fix.

ReSharper_by_Language__XAML__Quick-Fixes__remove_redundant_01

After applying the quick-fix, the namespace alias directive is removed.
ReSharper_by_Language__XAML__Quick-Fixes__remove_redundant_02

Remove type qualifier
When the type, to which the style should be applied, is specified in the TargetType attribute, there is no need to add a qualifier for each property of the Button class. ReSharper detects such cases and offers the quick-fix.
