Code Diagnostics

Note

This feature is currently available as a Community Technology Preview (CTP).

The code analysis feature helps you detect C# code errors as you type. If a code analyzer finds rule violations, they are reported in the code editor (as a squiggle under the invalid code) and in the Error List window.
