You can establish a custom font and color scheme, for more information, see Configuring Syntax Highlighting.
Default syntax highlighting:
ReSharper detects errors and highlights them with red curly line or displays unresolved symbols in red. Hover the pointer over the error to see its description as a tooltip. For more information about the ways to find out why the code is highlighted, see Finding Out What is Wrong with Your Code.
Since ReSharper has its own code inspections, you can specify whether to display them as errors, warnings, suggestions, hints, or not to display at all. For more information about configuring inspections, see Configuring Code Inspection Settings.
ReSharper does not only analyze errors in the current file, but also
inspects the whole solution taking the dependencies between files into account and shows
the results of analysis in the Errors in Solution window.
For more information, see Solution-Wide Analysis.
Inspect This is a shortcut to several analysis features. Those are rather powerful and allow you to see how values and method calls flow through you code. The list of available features depends on the current context.
For more information, see Call Tracking, Value Tracking and Viewing Type Hierarchy.
Code Completion features help you write code faster by providing a set of items to complete based on surrounding context. For more information, see Code Completion.
Three Code Completion features are available in Visual Basic:
ReSharper suggests namespaces, types, methods, fields, properties, etc.
Enum members are also included into basic completion list.
ReSharper filters items in code completion list according to the type expected in current context. Look at the example below, only those items that have string type are displayed in the drop-down list.
Import Symbol Completion
ReSharper provides completion items for types and extension methods that are not visible through import directives in current context.
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.
ReSharper provides the quick-fix to remove all such directives from a file.
If you use a symbol from a namespace that is not imported, ReSharper 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 times and new language features for asynchronous programming are thoroughly supported.
The GetQuotesAsync function contains the await operator, but the function isn't defined as asynchronous. ReSharper detects such mismatch and prompts 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 the method argument doesn't match the type of the corresponding method parameter, ReSharper suggests to change the type of 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 parameter's value, use this quick-fix.
Create method from usage
If there is a call of a method that does not exist yet, ReSharper provides the necessary quick-fix to create such method.
Examples of context actions
Add new format item
If you need to add some dynamic data to a string literal, use this context action.
It wraps the string literal with the String.Format method call, adds a placeholder at the current caret position and lets you specify the corresponding parameter.
Change member visibility
If you need to adjust member visibility, ReSharper provides a context action that allows to do this quickly.
Convert Function to Sub
In case you want to convert a Visual Basic .NET Function to a Sub, there's the corresponding context action as well.
Convert to property with backing field
You can easily transform an automatic property to a property with backing field. Place the caret at the name of an automatic property and press Alt+Enter. ReSharper suggests you the appropriate context action.
Create overload without parameter
For each parameter of a function there's a context action that will create a function without that parameter which calls the original function.
After you add a new member to a base class, the next logical step is to implement this member in all classes derived from the base class. You can write code manually, but a better decision is to apply the appropriate context action.
ReSharper automatically detects all derived classes and prompts you to decide where a base class member should be implemented and generates code.
Moving Code Elements is available in Visual Basic as well. For example, you can move a member declaration up or down within a type.
You can move a statement out of or into a block of code. For example, to move If statement out of For Each loop, press Ctrl+Shift+Alt+LeftCtrl+Shift+Alt+Left.
You can reorder parameters of a method call or a method declaration. For example, to move FileId argument to the right, press Ctrl+Shift+Alt+RightCtrl+Shift+Alt+Right.
