Sets the path to the common language runtime (CLR) loaded in the debugger.

Syntax

HRESULT SetCorPath(  
   LPCOLESTR pcstrCorPath  
);  

int SetCorPath(  
   string pcstrCorPath  
);  

Parameters

pcstrCorPath
[in] Path to the CLR loaded in the debugger.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Example

The following example shows how to implement this method for a ExpressionEvaluatorPackage object that exposes the IDebugExpressionEvaluator2 interface.
