I have tried adding <Message>
elements to tasks in a Visual Studio project file, in order to debug the build process. However, the elements have no effect on the text that is written to the Visual Studio output window.
Is there a way to write messages to the Visual Studio output window, by adding markup to the project being built?
This may help:
Under Tools → Options → Projects and Solutions → Build and Run, there’s the MSBuild project build output verbosity combo box. This controls how much info you want to see in the Output window.
