Devart Forums

Hello,

I'm using the last version of the Devart.Data.Oracle.EFCore 9.6.675.

And when i want to acces to my database, i have this error :
I run my application in 64x version and i have the X64 client install on my computer

I don't understand what I have to do for solve this error

Thanks for your help

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?

2. Make sure that:
a) Platform target=x64 in the properties of your project
b) your Oracle Client is located in the registry branch
HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\
instead of
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ORACLE\

3. Specify:
a) the Target framework property of your project
b) you are using .NET Standard Devart.* assemblies loaded from https://www.nuget.org/packages/devart.d ... cle.efcore, aren't you?

As a workaround, please connect in the Direct mode.

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

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 :)
