Below is a small/quick list for Code reviews. (We have mainly used it for Dynamics CRM plugins/custom workflows development, but same can be applied for other .net projects)

Technical – In context of methods being modified/created for current changes

• Validate for below
  • Database retrieve/query operation that can be avoided, if data is already available or can be collectively retrieved. (Very important because for performance)
  • Multiple/unwanted loops for same collection in a method
  • More checks can be added here…
• Naming convention

Identifier	Case	Example
Enum values	Pascal	FatalError
Read-only Static field	Pascal	RedValue
Method	Pascal	ToString
Parameter	Camel	typeName
Property	Pascal	BackColor

• No warnings must be there (as per the standard rule set being used)
• No commented code is present
• Comments
• Methods must have comments, preferably referencing and matching the algorithms and logic provided in the design
• Check spelling mistakes in method names/comments
• Defect number, CR number should not be referenced in code
• Press Ctrl+K+D (code formatting) to check if code document is formatted properly

Functional

Verify the code as per the requirements (document)

• For each functionality required there should be code with appropriate comments
• Check if the logic implemented matches with requirements mentioned
• Compare new changes with existing, validate if only required code is changed

Happy Coding!!
