When Entity Framework (EF) is used in MVC, the "system. Data. Entity" solution for the Assembly must be added

By default, only the reference of the LINQ assembly is added to Web. config generated in MVC. If Entity Framework (EF) is used as the orm of MVC, you need to add the Assembly reference in webconfig:

For example:

<Assemblies>
......

<Add Assembly = "system. xml. LINQ, version = 3.5.0.0, culture = neutral, publickeytoken = b77a5c561934e089"/>
<Add Assembly = "system. Data. LINQ, version = 3.5.0.0, culture = neutral, publickeytoken = b77a5c561934e089"/>
<Add Assembly = "system. Data. entity, version = 3.5.0.0, culture = neutral, publickeytoken = b77a5c561934e089"/>
</Assemblies>

Pagebasetype = "system. Web. MVC. viewpage, system. Web. MVC, version = 2.0.0.0, culture = neutral, publickeytoken = 31bf3856ad364e35"
Usercontrolbasetype = "system. Web. MVC. viewusercontrol, system. Web. MVC, version = 2.0.0.0, culture = neutral, publickeytoken = 31bf3856ad364e35">
