public class SchoolBL

show inheritance from IDisposable, i.e.

public class SchoolBL : IDisposable

It reads "In the main project, open the SchoolBL.cs file..." when was this created?

It is defined in the main project, and there's a reference from the test project to the main project.

SchoolBL.cs is created at the start of the Creating a Business-Logic Class section in this tutorial.

I do see that in the emdx class, but the complier does not want to see it, but seems to pointing to Instructor class which defines metadata.

The error reads "Error; 1; 'ContosoUniversity.Instructor' does not contain a definition for 'FirstMidName' ... File location..."

Please advise me where I have messed it up? Your kind response is appreciated.

Is it possible you missed a step where the property name was changed from FirstName to FirstMidName (while still mapped to table column named FirstName)?

After changing that, the test fails - as expected - due to the missing administrator validation in business logic.

When I throw the Duplicate Administrator Exception I get an error saying that the exception was unhandled by user code. It appears that the exception is not being passed by the event argument. I have declared the method for handling the exception but my code doesn't get to the OnInserted method. Any ideas?

Im using framework 4.0, i have a problem with the test class not getting the custom exception class. In fact the test crashes because the exception is unhandled in user code. I looked it over and over and then downloaded the project you made. Same result. Can it be there is there another behaviour for exceptions in 4.5?

Seems its a "feature" in VS2010. The workaround was using ctrl-f5 to debug or go into tools-options-debugging and click off "enable just my code"

I am using Visual Web Developer 2010 Express on Windows XP.

This tutorial is not currently scheduled to be updated, but if and when it is we'll clarify that that functionality is not available in Express editions of VS.
