Completion Behavior

Narrow down list on typing

Defines whether ReSharper should drop the items that do not match to the entered symbols and to the letters of a CamelHumps expression when displaying completion lists.

Automatically complete single item with

This group of options lets you enable or disable automatic commit for specific code completions (Basic completion, Smart completion, Import Symbol Completion) in cases where there is a single possible choice in the completion list. That is, as soon as the completion list narrows down to one item, the item is inserted automatically.

Automatically insert parenthesis after completion

Defines how parentheses are inserted when completing a method.

Note that you can type the opening parenthesis ( instead of Tab or Enter when a method is selected in the completion list. In this case the pair of parentheses will be inserted regardless of this option.

Match middle of identifiers

If this checkbox is selected, ReSharper matches letters at any position in the compound word according to the CamelHumps notation.

Sort items

This selector allows specifying how completion suggestions are sorted in the list. The By relevance option, selected by default, means that ReSharper applies heuristics to determine which suggestions are more relevant based on the context and your previous input. If necessary, you can choose Alphabetically to apply a more straightforward sorting order.

Smart Behavior in basic completion

This selector allows you to add expected types and/or inheritors to basic completion lists. If these features are enabled, more suggestions (static members, lambda expressions, and so on) appear. Also, the symbols that fit to the context are automatically preselected.

If a value other than 'None' is chosen, some performance degradation is possible.

Show import items in basic completion

When this checkbox is selected, completion items suggested by the Import Symbol Completion will automatically appear in completion lists of automatic completion and basic completion.

Show confirmation dialog before adding reference

This checkbox defines whether to show a confirmation dialog for the double import completion before it adds a new reference to the current project.

Replace keywords with Live Templates

This option, which is enabled by default, defines whether to suggest corresponding live templates when you type keywords like for, while, and so on. If this option is disabled, live templates are still available in the completion list but the preferred suggestion in this case is basic keyword completion.

Add special items to correct common errors (like Length vs. Count)

Use this checkbox to define whether to show suggestions for mistyped Length/Count in the completion list.

Insert space after keywords when spacing after is required

By default, ReSharper inserts necessary spaces when you pick keywords from the completion list, for example, when you choose public. If you type too fast, you can have a situation where you complete the suggestion and type space afterwards, so you can end up having two spaces in a row.

To avoid this problem, you can clear this checkbox and type all spaces manually.
