Hi,

Im writting a C# program to automate our builds utilizing the MSBUILD functionality. Alot of our code is written in C++. Does anyone know how to add the VCBUILD task to the engine.BuildProjectFile function? I've added my code snippet to the bottom of this message. I setup a log file to capture build error messages, and I get the following :

The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:\Windows\Microsoft.NET\Framework\v4.0.30319" directory.

Here's a code snippet of my code so far:

Code:
      BuildPropertyGroup group = new BuildPropertyGroup();
                group.SetProperty("Configuration", "Release");

                Microsoft.Build.BuildEngine.Engine engine = new Engine();

                // Instantiate a new FileLogger to generate build log
                FileLogger logger = new FileLogger();

                // Set the logfile parameter to indicate the log destination
                logger.Parameters = @"logfile=C:\temp\build.log";

                // Register the logger with the engine
                engine.RegisterLogger(logger);

                // Initialize code
                Boolean success = engine.BuildProjectFile(@"D:\Manitou\Releases\1.6.0\Fixes_1.6.0\Tapi\Boldphone\Boldphone.sln", new String[] { "Build" }, group);

                //Unregister all loggers to close the log file
                engine.UnregisterAllLoggers();

                if (success)
                {
                    Console.WriteLine("Build succeeded.");
                }
                else
                {
                    Console.WriteLine(@"Build failed. View C:\temp\build.log for details");
                }
Thanks for anyhelp on this!
