The .NET add-on performs the following steps before it begins with the execution of a Try Script run: 
               	 
            
 
            	 
            
               -  
                  		  The add-on compiles the .NET Assembly. 
                     		   
                  		   If the compilation fails the add-on does not execute the Try Script.

                  		  The Code Generation Engine generates the BDF/BDH files. 
                     		   
                  		    
                  			 
                  The engine checks if it has to overwrite old BDF/BDH files. Old files are overwritten only if there has been one of the following
                     changes made to the structure of the .NET test driver:

                  		  The add-on prompts you to execute the 
                     			 VirtualUser. If there is more than one 
                     			 VirtualUser class in the .NET test driver, you must choose which virtual user is to be executed.

                        				TrueLog Explorer option setting has been enabled,
