Code inspection and quick-fixes in Visual Basic .NET
Almost all JetBrains Rider's code analysis features available in C# (except for Value tracking) are also supported in VB.NET. You can find the detailed information on these features in the corresponding topics of the Code analysis section.
In this topic, you can find some examples of using code analysis features in VB.NET.
JetBrains Rider's static code analysis can detect more than 150 different errors and problems in VB.NET code.
To look through the list of available inspections for VB.NET, open the VB.NET node.page of JetBrains Rider settings Ctrl+Alt+S, and then expand the
JetBrains Rider not only analyzes errors in the current file, but also inspects the whole solution taking the dependencies between files into account. It shows the results of analysis in the All Soluiton Files tab of the Problems window Alt+6. For more information, see Solution-wide analysis.
Inspect This is a shortcut to several powerful analysis features that allow you to see how values and method calls flow through your code. The list of available features depends on the current context. For more information, see Call tracking, Value tracking.
Examples of Quick-fixes
Remove redundant 'imports'
If none of the symbols from a particular namespace are used, the corresponding
Imports directive is considered as redundant.
JetBrains Rider provides the quick-fix to remove all such directives from a file.
If you use a symbol from a namespace that is not imported, JetBrains Rider suggests to import the corresponding namespace and provides the necessary quick-fix.
Add 'Async' modifier
Asynchronous operations have some advantages over synchronous programming, so ReSharper keeps pace with the times and thoroughly supports the language features for asynchronous programming. The
GetQuotesAsync function contains the
await operator, but the function isn't defined as asynchronous. JetBrains Rider detects such a mismatch and prompts you to improve the code using the Add 'Async' modifier quick-fix. After applying the quick-fix, the missing modifier is added to the function declaration.
If the type of a method's argument doesn't match the type of the corresponding method parameter, JetBrains Rider suggests changing the type of the argument and provides the necessary quick-fix.
Initialize auto-property from constructor parameter
If you have a constructor parameter and you want to initialize an existing auto-property with the parameter's value, use this quick-fix.
Create method from usage
If there is a call of a method that does not exist yet, JetBrains Rider provides the necessary quick-fix to create such a method.
