EntityFramework 4.3.1 - MissingMethodException - Sql Compact

isntn · April 2012

I have my POCO model is seperate dll than my asp.net mvc 3 website.

I created new connection in LinqPad Beta: v4.41.01 selected option for Poco, provided path to custom dll, Chose DbContext, Chose via parameterless constructor.

This did not work, as I am using SqlServer Compact.

Then I created dummy.config file as follows:


<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.3.1.0,  Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  </configSections>
  <entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
    <parameters>
      <parameter value="System.Data.SqlServerCe.4.0" />
    </parameters>
  </defaultConnectionFactory>
</entityFramework>
    <connectionStrings>
        <add name="ModelContext"
             connectionString="data source=database.sdf"
             providerName="system.data.sqlserverce.4.0" />
    </connectionStrings>
</configuration>

With this, Test on connection is shown successful. Even, tree on left is also populated. But when I run any query, it throws exception as follows:
Method not found: 'System.Data.Entity.DbSet`1 InventoryModelContext.get_xxx()'.

Any solution or workaround?

Thanks in advance.

Also, note that this seems to be compilation error!

I got the exception. I am not able to use my dbContext with LinqPAD.

Note: But I exposed DBcontext via Odata. Used this Odata with LinqPAD and it works fine.
