Use Entity Framework in CLR Stored procedure

Question

I found a post from seven or so years ago that the Entity Framework could not be used in a CLR stored procedure. Has this been rectified in the past seven or so years? Is an update available that will allow the Entity Framework to work in a CLR stored procedure?

Answer 1

The normal reason you don't do this is that if you did, you would have to install all of .NET Framework assemblies that EF depends on into the database as unsafe assemblies, and you would have to update them every time the .NET Framework on the server was updated. As of EF 6.2 that list is :

smdiagnostics.dll
system.runtime.serialization.dll
system.dynamic.dll
microsoft.csharp.dll

This is in addition to installing updated versions of

entityframework.dll  
entityframework.sqlserver.dll

Which would come along with updated versions of your custom CLR dll.

And then you would have to start testing EF in SQL CLR to determine if it a) works and b) plays nicely in SQLCLR's unique hosting environment.
