Error Calling DbContext Contructor

Posted: Mon 21 Oct 2013 18:38
by guilford
We are using DevArt 7.2.104.0 against an Oracle 11g database. We are getting a "the type initializer for 'System.Data.Entity.Internal.AppConfig' threw an exception" error (error details at end of this post) calling the constructor of our DbContext Entity Model. We have not seen this error on our development workstations, but we see it on some of our Win 2008 production servers. I am hoping someone can point us in the right direction toward resolving this.

Our app.config file looks like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
<connectionStrings>
<add name="PROKEntitiesConnectionString" connectionString="metadata=res://*/ProkModel.csdl|res://*/ProkModel.ssdl|res://*/ProkModel.msl;provider=Devart.Data.Oracle;provider connection string="User Id={DBUSERNAME};Password={DBPASSWORD};Server={DBNAME};Persist Security Info=True;Pooling=False"" providerName="System.Data.EntityClient" />
</connectionStrings>

1. Have you specified the full stack trace? If not, please post it with all inner exceptions.
2. Please check again the app.config file of your deployed application. If there is the following entry

Code: Select all

<configSections>
  <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=X.X.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
replace X.X.0.0 with the actual version of EntityFramework.dll used by the application.
3. If this doesn't help, send us a small test project so that we can deploy it in our environment and reproduce the error.

Thank you for the response. I double-checked to make sure we had that section in our config file and we were missing it, so I added it. I redeployed everything to our server and now I get the error below (which seems to make it into the constructor, so it makes it a little farther than before, but now crashes on a config line in the constructor). The line in the constructor where is fails is this:

var config = Devart.Data.Oracle.Entity.Configuration.OracleEntityProviderConfig.Instance;

Our newly updated config file is this:
