I have extensive experience with both .NET Framework and .NET Core. In my previous role, I developed applications using .NET Framework for legacy systems and migrated them to .NET Core for better performance and cross-platform compatibility. I am proficient in leveraging the strengths of each framework to build scalable and efficient applications.

I use Visual Studio's debugging tools extensively to identify and resolve issues in .NET applications. I set breakpoints, inspect variables, and use the immediate window to trace code execution. Additionally, I analyze logs and error messages to pinpoint the root cause of problems and implement effective solutions.

I have worked extensively with C# and am well-versed in its features such as LINQ, async/await, and lambda expressions. I use these features to write clean, maintainable, and efficient code. I also stay updated with the latest C# language advancements and apply them to enhance application performance.

I follow best practices such as input validation, parameterized queries, and encryption to secure .NET applications. I also implement role-based access control and use libraries like ASP.NET Identity for authentication and authorization. Regular code reviews and security audits are part of my development process.

I have integrated various databases such as SQL Server, MySQL, and MongoDB with .NET applications. I use Entity Framework and ADO.NET for data access and ensure efficient querying and data management. I also optimize database interactions to improve application performance.
