License issue

Post by GaultierLarge » Tue 23 Jul 2019 09:03

Hello,

we use the trial of Devart.Data.Oracle.EFCore with EF CORE 2.2, it's work fine. After we buy a license pro, and we had our license key in the connection string with the tag LicenseKey, (like it wrote in the doc) but we have this error message :


Feature is not supported. This error is thrown by Devart .NET Standard assemblies if license key validation fails. Possible reasons: 1. License key is not found, refer to the "Licensing .NET Standard (.NET Core) Projects" article in the product documentation. 2. Your product edition (the key was generated for) doesn't support the feature you are trying to use, refer to the editions matrix. 3. Your key is outdated for using the current product version, renew the license key in the Customer Portal.

What can i do for my app work with my license pro?

Best regards

1. Make sure that you set License Key to the activation key (not license number) value from your Devart Account.

2. Your project type is .NET Core (or .NET Standard), isn't it? Be aware that UWP is currently not supported.

I verify, we put the activation key in the License key parameter

Like this :

 

Code: Select all

	"User Id=[user];Password=[password];Data Source=[ip];port=1521;Direct=true;SID=MESDEV;License Key=yaHImBztDqND+HIwhP1TJpJZ4kKKRTDqm0in9Guh1KpgYt0b8ecAgl9xnl84P8RYTxE48pRJZkMnxKCY2Pp/eXyBwS8tWpSOjzbmhbMwqgXpHeBRnoUDJbFKgSdrQS8AvN89kqnSGK0oCY7x+trltf/Rvg8/vdKh9dn6kw+l4XP4Q=="
(it's not our real license key)

Our application is an ASP.Net Core 2.2 application.

We have nothing to do more than put the key in the connection string and download and use the nuget package Devart.Data.Oracle.EFCore ?

1. Make sure that you added License Key to the connection string that is actually used by the runtime. Maybe there are several connection strings in your code.

2. Please create a simple console .NET Core project and execute:

Code: Select all

  var conn = new OracleConnection("your_conn_string_with_License_Key");
  conn.Open();
Does it work? If not, contact us and specify your email used when registering dotConnect for Oracle Professional.

Please send us a small test project so that we can reproduce the error in our environment.

You are using the license key from Standard Edition, it doesn't support Entity Framework: https://www.devart.com/dotconnect/oracle/editions.html. Please upgrade your edition and use the new license key.
