`System.Data.Linq.dll` is a library file associated with the Microsoft® .NET Framework, developed by Microsoft Corporation. Specifically, this dynamic link library (DLL) file pertains to LINQ to SQL, which is a component of the .NET Framework that provides a run-time infrastructure for managing relational data as objects.
LINQ, which stands for Language Integrated Query, is a set of technologies incorporated in the .NET Framework that adds native data querying capabilities to .NET languages. LINQ to SQL, in particular, is a component that allows developers to model a relational database using .NET classes. Essentially, it bridges the gap between the world of objects in .NET and the world of relational databases, such as Microsoft SQL Server.
With the help of `System.Data.Linq.dll`, developers can create .NET objects that map directly to the structure of their database. They can then use LINQ queries to interact with the database, and the library will handle the conversion of these queries into SQL statements that the database can understand.
For regular users who might not be into software development, it's enough to know that `System.Data.Linq.dll` is a crucial file for certain applications built using the .NET Framework, especially those that interact with databases. If there are issues or errors related to this DLL, it could indicate problems with the .NET Framework installation or with a specific application that relies on it. In such cases, repairing the .NET Framework or the application in question might be necessary.
