Installing a C# CLR Assembly in RDS for SQL Server

Microsoft SQL Server provides assemblies to make database operations simple and convenient.

When you restore data to a new or an existing DB instance, the clr enabled parameter is disabled by default. To use the CLR integration function, you need to enable clr enabled first. For details about how to enable the CLR integration function, see Enabling CLR Integration.
