Hi,

While generating .NET CORE PROJECT Telerik Report with oracle db , facing below error and cannot go further. What would be the cause of error?.

Report preview with data happening in Report designer it's not rendering on browser.

 

-----------------------------------------------------

appsetting.json file configuration :

  "ConnectionStrings": 
    {
      "name": "dbsource",
       "connectionString": "Data Source=dbsource;User ID=user;Password=password",
      "providerName": "Oracle.ManagedDataAccess.Core"
    }
  

 

-----------------------

 

Thanks

Hi Sarat,

I would recommend registering the data provider as explained in the How to register a DbProviderFactory in a .NET Core project  KB article.
