INTRODUCTION

This article describes the support policy for untested Microsoft .NET Framework assemblies in the .NET Framework common language runtime (CLR)-hosted environment in Microsoft SQL Server.

MORE INFORMATION

When you register an assembly that references an untested .NET Framework assembly in SQL Server, you may receive the following warning message:

Warning: The Microsoft .Net frameworks assembly 'AssemblyName' you are registering is not fully tested in SQL Server hosted environment.

The message means that the .NET Framework assembly has not been tested in the SQL Server CLR-hosted environment. Therefore, the assembly is not supported in the SQL Server 2005 CLR-hosted environment.

An untested .NET Framework assembly may decide to exit its host process when a critical condition such as low-memory condition occurs. You can use the assembly in the SQL Server 2005 CLR-hosted environment at your own risk. However, Microsoft SQL Server Product Support Services (PSS) will not help you use and troubleshoot issues that are associated with an unsupported .NET Framework assembly. If PSS determines that a particular unsupported assembly causes SQL Server issues, you may be asked to stop using the assembly. Additionally, you may be asked to stop using the assembly temporarily when PSS troubleshoots a particular SQL Server issue if it is necessary.

Additonally, you must maintain these assemblies after you upgrade the Microsoft .NET Framework. For more information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:

The following .NET Framework assemblies are supported in the SQL Server CLR-hosted environment:
