Nuget package update - Microsoft.Data.SqlClient.SNI.x64

Please try the following steps:

1) close VS Instance, delete nuget.config file under C:\Users\xxx(current use account)\AppData\Roaming\NuGet .

2) delete .vs hidden folder under your solution folder, bin and obj folder then restart your project to test again.

3) Please try to create a new empty project in VS2019 and test whether you can install the package Microsoft.Data.SqlClient .

If you cannot install it, you should note that whether your VS or OS has broken. If the new project has no error, the issue is your project itself. You can try the above steps to troubleshoot the issue.

If the issue still persists in the new project,

You can try to repair VS or update VS to the latest version.

Also , try to update OS or use the System File Checker tool to repair missing or corrupted system files .

Besides , try another PC to test whether the issue persists.

Microsoft.Data.SqlClient.SNI.X64 or X32 files need to be removed from release folder before creating package.

Microsoft.Data.SqlClient.SNI.X64 will be added automatically while adding Microsoft.Data.SqlClient.

So, remove the dll before creating the package and then try installing it.
