title: What .Net assemblies are integrated into the SQL Server 2008 R2 CLR as standard?
body: <p>I have an existing assembly that has been used within SQL Server for some time. Today I added some experimental code that references <code>System.Data.Linq</code>. Creating the assembly within <strong>SQL 2008 R2</strong> resulted in this error:</p>
  
  <blockquote>
    <p><em>Assembly 'system.data.linq, version=3.5.0.0, culture=neutral, publickeytoken=b77a5c561934e089.' was not found in the SQL catalog.</em></p>
  </blockquote>
  
  <p>This is not entirely unexpected, but I was wondering how to determine what the full set of standard '<strong>core</strong>' assembles is within 2008 R2. Presumably <code>System.Data.Linq</code> isn't one of them - but I would like to confirm this and also confirm what assemblies are provided as standard.</p>
