A System.Web.Compilation.ClientBuildManagerCallback object can be passed to the System.Web.Compilation.ClientBuildManager object through the ClientBuildManager.PrecompileApplication(ClientBuildManagerCallback) method. When an error is encountered during an application build, the error is passed as an argument to either the ClientBuildManagerCallback.ReportCompilerError(System.CodeDom.Compiler.CompilerError) or the ClientBuildManagerCallback.ReportParseError(System.Web.ParserError) method, depending on the type of error. When you create a class that derives from the System.Web.Compilation.ClientBuildManagerCallback class, you can implement these methods and retrieve the error.
