08-May-2023In .NET, the problem of DLLs (Dynamic Link Libraries) is solved using the Common Language Runtime (CLR) and the Global Assembly Cache (GAC).
The CLR is the component of the .NET Framework that manages the execution of .NET programs. When a .NET program runs, the CLR loads the required DLLs into memory and resolves dependencies between them. This gives your program access to all the code and resources it needs at run time.
The GAC is a central repository of .NET assemblies (DLLs or EXEs) intended to be shared among multiple applications. Assemblies added to the GAC are strongly named with a unique identifier and digital signature to prevent tampering or replacement. If an application needs to use an assembly from his GAC, it can reference the assembly's strong name in its code. The CLR will automatically find and load the correct version of the assembly from the GAC.
Additionally, .NET provides a mechanism called private assemblies to load DLLs specific to a particular application. Private assemblies are loaded from the same folder as the application executable.
Overall, .NET's use of the CLR and GAC provides a safe and reliable mechanism for sharing and managing assemblies across multiple applications, while ensuring that all code required by a .NET application at run time is It provides a robust solution to DLL problems by ensuring access to and resources. .

dynamic link library (DLL).
.Net Framework provides operating systems with a Global
Assembly Cache. This Cache is a repository for all the .Net
components that are shared globally on a particular
machine. When a .Net component is installed onto the
machine, the Global Assembly Cache looks at its version,
its public key, and its language information and creates a
strong name for the component. The component is then
registered in the repository and indexed by its strong
name, so there is no confusion between different versions
of the same component, or DLL.
