Devart Forums

I cannot get a code-first version working for Salesforce using either the ADO.Net Entity Data Model Code-First Wizard or the Entity Developer DbContext Template (using either the stand-alone app or VS2012|2015 extension).

I've trolled the support docs and forums, but can not find anything on "dotConnect Salesforce" specifically. I am aware of the below article and Entity Framework Tutorial help docs and I believe I have setup the app.config setup correctly.
http://blog.devart.com/entity-framework ... #CodeFirst
https://www.devart.com/dotconnect/salesforce/docs/


If I use the Entity Developer DbContext version it hits an exception when the first query attempts to execute (see below), or the ADO EDM wizard fails and throws the same exception when trying to create the Code-First model (getting the same "The method or operation is not implemented." message either way)

SalesforceDbContext context = new SalesforceDbContext();
var query = from it in context.Accounts
orderby it.Name
select it; <== Failing Instruction.

foreach (Account a in context)
Console.WriteLine("{0} | {1}", a.Name, a.Id)

System.NotImplementedException was unhandled

We cannot reproduce the error in our environment with the newest (2.5.813) build of dotConnect for Salesforce. Please send us a small test project for reproducing.

I'm only running 2.5.804.0. Isn't the assembly supposed to automatically update when a project contains the Devart.Data.Salesforce references?

1. Thank you for the test project. We have reproduced the issue and are investigating it. We will notify you about the result.

2. The dotConnect for Salesforce installation puts the policy.*.Devart.* files to GAC. So the newer provider assemblies will be loaded in the process of application. But there is an issue in a current implementation: reference to \EF6\Devart.Data.Salesforce.Entity.dll (2.5.804.6) will be redirected to the \EF5\Devart.Data.Salesforce.Entity.dll (2.5.813.0) assembly.
If this is not the situation you are asking about, please describe your scenario.

I've implemented the newest version and added the Database.SetInitializer line of code, but am still getting the same error. If you were able to recreate the error and have since resolved it, can you send me the working project? I'm really getting down to a deadline and need to know if this technology is going to be a viable solution in the near future.
