Cases when .NET Core does not work

1. Unsupported platforms: .NET Core does not work on certain platforms that do not meet its requirements. For example, it is not compatible with older versions of Windows such as Windows XP and Windows Server 2003. Additionally, it does not support some specialized operating systems like Windows RT and Windows Phone.
2. Limited third-party library support: Although .NET Core has a growing ecosystem of libraries and frameworks, there may be cases where specific third-party libraries or components are not available or fully compatible with .NET Core. This can be a limitation if your project heavily relies on such libraries.
3. Legacy system dependencies: If your application has dependencies on legacy systems or technologies that are not compatible with .NET Core, it may not be feasible to migrate to .NET Core without significant effort or rewriting of those dependencies. This can be a deterrent in certain scenarios.
4. Hardware or platform-specific requirements: Some applications have hardware or platform-specific requirements that are not supported by .NET Core. For example, if your application requires direct access to certain hardware components or relies on specific platform features that are not available in .NET Core, it may not be suitable for your use case.
5. Performance-sensitive applications: While .NET Core offers excellent performance, there may be cases where extreme performance requirements cannot be met by the framework. In such scenarios, lower-level languages like C or C++ might be more suitable for achieving optimal performance.
6. Dependency on specific Windows-only features: If your application heavily depends on Windows-only features or APIs that are not available in .NET Core, it may not be feasible to migrate to .NET Core without significant modifications or workarounds.
7. Large codebases with complex dependencies: Migrating a large codebase with complex dependencies to .NET Core can be a challenging and time-consuming task. In some cases, the effort required for migration may outweigh the benefits of using .NET Core.

It is important to note that while there may be cases where .NET Core does not work, it is a versatile and widely adopted framework that can cater to the needs of various application types and platforms. The decision to use .NET Core should be based on a careful evaluation of your specific requirements and constraints.
