Which specific version of .NET Core have you used in your projects?

The specific version of .NET Core I used in projects depends on the requirements and the development timeline. For example, versions 3.1 and 5.0 were frequently used because they were stable and supported Long-Term Support (LTS).

.NET Core 3.1 was widely used for server applications and APIs, and starting with .NET 5.0, the platform unified into a single .NET, simplifying development and expanding capabilities.

When choosing a version, it is important to consider support, compatibility with libraries, and project requirements.
