GaultierLarge

Hi

I do the test with the an empty console app, it works.

I verify, my connectionstring, in debug in my Asp.Net core app, it's the good connection string which is use with the license key. but it's not working with the same error message

Code: Select all

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 Your key is outdated for using the current product version, renew the license key in the Customer Portal.

Update : I try to do an empty console app, with entity Framework and i have the same issue
I think i miss something, but i don't see what, do you have an Idea?

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 ?

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 Your key is outdated for using the current product version, renew the license key in the Customer Portal.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

Thanks for your anwser, next, my anwser to your questions

1. Please check workability of your Oracle Client. For example: can you connect with SQL*Plus or Oracle SQL Developer using the same Oracle Client?

I tried with SQL Developper and it's OK

2. Make sure that:
a) Platform target=x64 in the properties of your project

=> It's OK, I target the X64 plateform

b) your Oracle Client is located in the registry branch
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\
instead of
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ORACLE\

=> It's OK, and in the error message, there is the path of the x64 client, it's why I don't understand this error

3. Specify:
a) the Target framework property of your project

.net core 2.2

b) you are using .NET Standard Devart.* assemblies loaded from https://www.nuget.org/packages/devart.d ... cle.efcore, aren't you?

Yes we use this package

As a workaround, please connect in the Direct mode.

Direct Mode is Working thx :)
