I have a desktop application that works with SQL Server CE and EF using a code-first approach, I have large volume of users working with this.
The connection string that I am passing to DbContext class constructor,
#"Data Source=" + Path.Combine("Path to local app data", "Databasename.sdf") + ";Password=mypassword"
But on one of the Windows 7 SP1 (32 bit) machines, I am getting following error:
System.InvalidOperationException: Unable to complete operation. The supplied SqlConnection does not specify an initial catalog or AttachDBFileName.

I am unable to figure out what is going wrong with that particular machine, because the same thing works for other Windows 7 users.
Plus I also tried re-installing SQL Server CE Runtime 3.5 SP2, but no luck.
To add more info, the database is successfully created in the specified location, but I'm unable to do other operations.

I have an ASP.NET application running under .NET Framework 4.7.2.
In my application I am trying to connect to my Sharepoint site to create or rename folders.
Unfortunately I am getting below error.
I've been searching around on the internet and found a lot of articles talking about TLS but my application has TLS 1.2 by default due to the .NET Framework 4.7.2.
Does anyone would know the reason/background of the error?
(I don't have the error on my local machine (no SSL), error only occurs after deploying to my hosting environment with SSL)

There are at least two parts of a TLS connection: version and ciphersuites. You need to check the ciphers you have on your local machine:
https://learn.microsoft.com/en-us/powershell/module/tls/get-tlsciphersuite?view=windowsserver2022-ps
Then you should check the ciphers that are available on the sharepoint site:
https://www.ssllabs.com/ssltest/
At least one of the ciphers must match in order to complete the connection.

You can access the IBM database system with the IBM Data Server Provider for .Net.
This message is returned when there is a problem with the database product installation. This message can also be returned when the Windows extended security feature is enabled and the ID that is used to start the Internet Information Systems (IIS) service does not belong to the DB2ADMNS group or to the DB2USERS group.
The reason code for this message is intended for IBM support personnel only.
Hope this helps.
I am trying to scaffolf an Entityframeworkcore DbContext for a UWP app from a Sqlite databse. I do:
Scaffold-DbContext "data source=C:\SqliteDbFiles\Sqlite.db" Microsoft.EntityFrameworkCore.Sqlite

Any help would be greatly appreciated
The version of sqlite3.dll used at runtime on UWP won't work at design-time. You can manually download one of the Precompiled Binaries for Windows and copy it to the output directory (e.g. bin\x86\Debug) before running the command.
A simpler solution might be to scaffold the DbContext in a non-UWP project and just copy the classes into the UWP project after they're generated.

I have fixed this by recreating edmx with unmanaged driver instead of managed Driver. Application works perfect. !! used ODAC 12c Release 4.

I have SQLite installed now (though, I don't think that matters... Bonobo comes with its own SQLite dlls. I AM running on a 64 bit system. I don't know if that has anything to do with compatability. I've followed the installation instructions on the Bonobo site to the tee, but I still get this error and Google hasn't provided any answers for me. Could anyone point me in the right direction?
You should try to set the right security options for your IIS.
