I use the dotConnect for PostgreSQL version 7.7.819.0 to connect my Asp.NET Web API application running on IIS to a PostgreSQL 9.5 database running on Apache Tomcat on a separate virtual server (VPS).
When I try to add multiple records locally, while my the app on my machine is connected to the online database, everything works fine.
When I try to add multiple records online, I get the error from the title. The error occurs when the dispose method on my unit of work is triggered, so when the records are stored in the database.

The weird thing is, I am not saving any geo information, just plain ASP.NET datatypes

Full error:

Please make sure that your project is NOT set up for using System.Data.SqlClient provider (there are its classes in your stack trace).

If this doesn't help, upload a small test project with the corresponding DDL/DML script to ftp://ftp.devart.com (credentials: anonymous / yourEmail).

fixed!

had to include

Code: Select all

 <dependentAssembly>
        <assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
      </dependentAssembly>

in the web.config

I used this to determine what the version number used on my server

Code: Select all

AppDomain currentDomain = AppDomain.CurrentDomain; 
Assembly[] assems = currentDomain.GetAssemblies(); 
foreach (Assembly assembly in assems) { 
_logger.Info(assembly.GetName().FullName); 
}

_logger is a Nlog logger

Thank you for confirming the fix.
