Summary: This document provides basic information about the extension providing Entity Framework support for C# and VB.NET

What's new?



This extension provides support for Entity Framework. The calculation of Automated Function Points for your .NET analyses will be supplemented through the creation of new objects and links specific to Entity Framework framework that will link back to objects/links produced by the base .NET analyzer.

In what situation should you install this extension?

If your .NET application contains Entity Framework source code and you want to view these object types and their links, then you should install this extension. More specifically the extension will identify:

  • "use" links from Entity Framework objects to participating Database tables
  • "rely on" links from C#/VB.NET Classes to Entity Wrapper objects

Entity Framework support

Entity Framework is delivered with the .NET Framework. Therefore the following .NET frameworks are supported by this extension:

3.0 and above(tick)

Supported Annotations in code-first


Supported methods in fluent api

System.Data.Entity.DbContext.OnModelCreating( DbModelBuilder modelBuilder )

Supported tags in .edmx file




Function Point, Quality and Sizing support

This extension provides the following support:

  • Function Points (transactions): a green tick indicates that OMG Function Point counting and Transaction Risk Index are supported
  • Quality and Sizing: a green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist

CAST AIP compatibility

This extension is compatible with:

CAST AIP release
Supported Technology
8.3.x(tick)C# and VB.NET
8.2.x(tick)C# and VB.NET

Supported DBMS servers

This extension is compatible with the following DBMS servers:



Microsoft SQL Server(error)


(tick)An installation of any compatible release of CAST AIP (see table above)

Download and installation instructions

The extension will be automatically downloaded and installed in CAST Console. You can manage the extension using the Application - Extensions interface:

CAST Transaction Configuration Center (TCC) configuration

In Entity Framework ≥ 1.1, if you are using the extension with CAST AIP ≥ 8.3.x, a set of Entity specific items are now automatically imported when the extension is installed. These items will be available in the CAST Transaction Configuration Center (click to enlarge):

Manual import action for CAST AIP ≤ 8.2.x (optional)

 Click here to expand...
  • Locate the .TCCSetup file in the extension folder: Configuration\TCC\DotNet_Entity.TCCSetup
  • In the CAST Transaction Configuration Center, ensure you have selected the Templates node:

  • This .TCCSetup file is to be imported into the CAST Transaction Calibration Center using either the:
    • File > Import Configuration menu option:

    • Or right clicking on the Template node and selecting Import Configuration:

  • The import of the "DotNet_Entity.TCCSetup" file will provide you with a sample Transaction End point in the Free Definition node under Templates (click to enlarge):

  • Now right click the one of the items and select copy:

  • Paste the item into the equivalent node under the Application, for example, below we have copied it into the Application MEUDON:

  • Repeat the copy / paste process for all items.

What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner. The following objects and links will be displayed in CAST Enlighten:

Because CAST cannot be absolutely certain that the C#/VB.NET class is "entity associated", these rely-on links will always be flagged as "dynamic" and will therefore always appear in the Dynamic Link Manager for review.

In this section we list the most significant functional limitations that may affect the analysis of applications using Entity Framework:

  • Analyzing the participating database tables is mandatory for the extension to work correctly.
  • No support for links between LINQ and SQL objects
  • Entity Framework objects are not correctly presented in the CAST dashboards
  • Enum Collections are not supported.
  • DBContexts are not supported.
  • Not all Entity Framework and Entity Core namespaces are supported and the analysis log may contain warning about these missing namespaces.
  • No labels
