Public Property DebuggerLanguageExpressionEvaluator As String
public string DebuggerLanguageExpressionEvaluator { get; set; }
public:
property String^ DebuggerLanguageExpressionEvaluator {

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]
