3. What are static code analysis tools?
These tools helps to maintain software code automatically.
They help to detect errors and problems before compiling the code.
These tools instantly tracks the writable code and highlights mistakes

4. Why static code analysis is needed?
Analysis helps find most common made mistakes in code:
Unused added libraries
Unplaced but needed null checkers
Unreachable code detection
Unassigned variables
It also helps to write code faster with code generation feature.

5. When we should use these tools?
Same coding style
Protection from commonly made mistakes
Track quality of code
Write code faster

6. About ReSharper
ReSharper is Visual Studio extension for C#, VB.NET, ASP.NET, C++, JavaScript technologies.
It is based on static code analysis.
It is well known and most used extension for IDE that provides quick-fixes, highlights to improve code in one way or another.

7. Code Quality Analysis Software code problems are classified in:
Errors
Warnings
Suggestions
Hints
Coding style templates can be customizable.
Problems that are detected and fixed:
Code that will not be compiled or will have negative impact
Unreachable code
Loops are remodeled in LINQ, keyword var is used in type definition.
Reducing nesting
Etc…

8. Refactoring Facts about resharper:
All found errors in code can be automatically fixed
Usually errors are fixed 1 by 1 not all at once.
Sometimes it is possible to contract ~10 lines of code to just 1 line of LINQ statement.
In some cases there was found that a project of LoC, had about of problems that where found in under 5minutes using ReSharper.

9. Warnings, suggestions and hints
ReSharper informs you about redundant casts, incorrect format strings, declared but never used local variables, etc. 
Suggestions provide insights into code structure, drawing your attention to things that aren't necessarily bad or wrong, but probably useful to know.
A hint simply brings your attention to a particular code detail and recommends a way of improvement.

Possible to add more tags
Useful for detecting places that needs to be modified.
Tags are marked in blue color so it would have more visibility for developer.

12. Coding Assistance Syntax Highlighting Context Actions
Complete Statement Ctrl + Shift + Enter

13. Coding Assistance Parameter Info Ctrl + Shift + Space
Importing Namespaces Alt + Enter

14. Coding Assistance
Automaticaly shows begining of brackets, when mouse is over the end of brackets in code.
Current code line marking
Automaticaly close brackets
Extend / shrink code fast Ctrl+Alt+Right / Left
All coding assistance features are customizable and can be turned off if needed.

15. Code Completion Drop down suggestion: Ctrl + Space
Expands standart Visual Studio Intelli Sense drop down list
Suggests variable names
Suggests data type names and casts
Drop down suggestions usually fits many developer needs, so they most often are required just to press Ctrl + Space, Enter, Ctrl + Space…

Convert Abstract Class to Interface and vice-versia
Introduce Parameter
Make Method Static/Shared and vice-versia
Move String to Resource
Push / Pull members up and down
Rename in whole program, file
Convert property to Auto-Property
Inline fields, methods
