Describe your professional experience working with the .NET platform.

My experience with the .NET platform includes developing applications in C# using the .NET Framework and .NET Core/.NET 5+.

I have created both console and web applications (ASP.NET Core), as well as REST APIs. I used Entity Framework for database interactions, LINQ for convenient data queries.

I am also familiar with the MSBuild build system, NuGet for package management, and used Visual Studio as my main IDE. In projects, I applied design patterns and wrote unit tests using MSTest and xUnit.

Example of a simple method in C#:

public class Calculator
{
    public int Add(int a, int b)
    {
        return a + b;
    }
}
