Hi DevExpress
I see by the documentation that XPO supports Pervasive.SQL 9 Pervasive.Data.SqlClient.dll - 2.10.0.15. Am I correct in assuming that this support is for .Net 1.1 only?
I was look to migrate/rewrite an legacy app in .Net 2.0 that uses PSQL using XPO and Pervasive.SQL 9, is this possible or am I clean out of luck?
Thanks
Bernard

Hello Bernard,
Yes, it's possible. Actually, the mentioned assembly also works correctly with the .Net Framework 2.0. So, you can easily convert your application to VS2005.
Please feel free to contact us if you need any additional assistance in this regard. We will be happy to help you.
Thanks,
Stan.
Hi Stan,
Thanks for the reply…
Attached is a sample project (XAF) which fails as follows:

I am not sure if you handle this as it XAF. The "eXpressAppFramework.log" is in the zip file.
The version of the Pervasive.Data.SqlClient provider that I am using is 2.10.1.2. The one available on their website.
Thanks
Bernard.
Hi Bernard,
Thank you for the update. This problem appears because of an omission in XPO. I have registered a new suggestion in the support center devoted to this problem:
Raise the SchemaCorrectionNeed exception in the Pervasive adapter
Thanks,
