Shader Development with HLSL
This video shows the main features ReSharper has for HLSL:
Initial support for HLSL includes the following:
Navigation to HLSL files.
Syntax highlighting and highlighting for syntax errors.
Tooltips for code elements with type information and documentation.
Semantic code analysis checks.
A few useful inspections with quick-fixes.
Smart suggestions in completion lists.
Refactorings, which are experimental, but Rename, Inline Variable, Introduce Variable, and Change Signature already work for many cases.
