In the project-properties is a setting "Treat warnings as errors" which you apparently switched on.

project-properties

To undo: Project->Properties->Build->Treat warnings as errors->None
(None is the default-setting for new projects.)

Read this for reference.

Note:
It's certainly still a good idea to set this setting to All, to ensure the code is error- and "garbage"-free.

To treat all compiler warnings as compilation errors:

  1. With a project selected in Solution Explorer, on the Project menu, click Properties.
  2. Click the Compile tab.
  3. Select the Treat all warnings as errors check box. (or select the build setting and change the “treat warnings as errors” settings to TRUE)

To disable all compiler warnings

  1. With a project selected in Solution Explorer, on the Project menu click Properties.
  2. Click the Compile tab.
  3. Select the Disable all warnings check box. (or select the build setting and change the “treat warnings as errors” settings to FALSE.)
