SQL Server Reporting Services (SSRS) & .NET

When using Reporting Services on the Server for the first time, you might find that reports won’t run in Visual Studio or on the web.

The error you get is: “Execution of user code in the .NET Framework is disabled. Enable clr enabled configuration option.”

By default .NET Framework is disabled in SQL2005 and SQL2008.

To enable it in 2005:
Explore "SQL Server 2005/Configuration Tools/Surface Area Configuration" in your Start menu.
2. Select "Surface Area Configuration for Features"
3. For the "CLR Integration" option, activate it and save.

To enable it in 2008:
sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'clr enabled', 1;
GO
RECONFIGURE;
GO
