Syntax

'Declaration
Public Property DebuggerLanguageExpressionEvaluator As String

'Usage
Dim instance As ProvideLanguageServiceAttribute 
Dim value As String 

value = instance.DebuggerLanguageExpressionEvaluator

instance.DebuggerLanguageExpressionEvaluator = value

public string DebuggerLanguageExpressionEvaluator { get; set; }

public:
property String^ DebuggerLanguageExpressionEvaluator {
    String^ get ();
    void set (String^ value);
}

public function get DebuggerLanguageExpressionEvaluator () : String 
public function set DebuggerLanguageExpressionEvaluator (value : String)

Property Value

Type: System.String
Returns a string containing the GUID of an expression evaluator; otherwise, returns a null value.

Remarks

A language service can interact with a debugger when a program is being debugged. Visual Studio can be told about which expression evaluator to use with a particular language service to avoid having to load a full debug engine.

This property is available to any language service implementation.

The default is a null value, indicating no associated expression evaluator is available.

The registry entry looks like this:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[X.Y]\Languages\Language Services\
  [Language Name]\
    Debugger Languages\
      [Expression Evaluator GUID] = reg_sz: [language name]

Examples

                            MyConstants.languageName,            // Required
                            MyConstants.languageNameResourceID,  // Required
        // Optional language service properties
