You can spend less time on routine, repetitive manual work and instead focus on the task at hand. A robust set of features for automatic error-checking and code correction cuts development time and increases your efficiency. You will find that ReSharper quickly pays back its cost in increased developer productivity and improved code quality. With ReSharper, .NET developers can truly experience what we mean when we say "The drive to develop".

ReSharper 2019.3 helps you improve your productivity by offering the following features:
Code quality analysis
With its design-time code inspection for all supported languages, ReSharper tells you right away if your code contains errors or can be improved. If necessary, you can also run static code analysis in any scope up to the entire solution.
Fixes to detected code issues
Not only does ReSharper warn you when there is a problem in your code, but it also provides quick-fixes to eliminate errors and code smells automatically.
Project dependency analysis
Invaluable for large solutions, ReSharper builds project hierarchies and visualizes project dependency diagram, which you can save and compare with new solution states at various stages, all without compiling anything.
Decompiling third-party code
An integrated decompiler lets you navigate to code in referenced assemblies; if an assembly is not referenced, you can open and browse it with the Assembly Explorer window enjoying the same navigation features as those you have for the source code.
You don't have to write properties, overloads, implementations, and comparers by hand: use code generation actions to handle boilerplate code faster.
Safe change of your code base
Enjoy solution-wide refactorings to safely change your code base. Whether you need to revitalize legacy code or put your project structure in order, you can lean on ReSharper.
Compliance to coding standards
Code formatting, naming style assistance, and many other code style preferences which you can quickly enforce with code cleanup, allow you to get rid of unused code and ensure compliance to coding standards.
ReSharper extensions, which include full-fledged plug-ins, sets of templates, structural search and replace patterns, and more, are extremely easy to discover, install, and update. For more information, see ReSharper plugins web page.
Command line tools
If you like the way ReSharper inspects your code, you can run code inspection or find code duplicates in your CI server or version control system with standalone command-line tools.
