 ## Create a project template
 
 Project templates produce ready-to-run projects that make it easy for users to start with a working set of code. .NET includes a few project templates such as a console application or a class library. In this example, you create a new console application project that replaces the standard "Hello World" console output with one that runs asynchronously.

 ## Use Debug build configuration
 
 *Debug* and *Release* are Visual Studio's built-in build configurations. You use the Debug build configuration for debugging and the Release configuration for the final release distribution.
 
 In the Debug configuration, a program compiles with full symbolic debug information and no optimization. Optimization complicates debugging, because the relationship between source code and generated instructions is more complex. The release configuration of a program has no symbolic debug information and is fully optimized.
 
- By default, Visual Studio uses the Debug build configuration, so you don't need to change it before debugging.
