Error after upgrading to Microsoft.Data.SqlClient 4

After upgrading to Microsoft.Data.SqlClient 4, I immediatelly started to get connection failures.

Let’s have a look at the exact error message:

A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.)

The reason of this error is that with the release of version 4.0, a breaking change was introduced to improve security:

The default value of the `Encrypt` connection option changed from `false` to `true`. With the increased emphasis on secure-by-default, the growing use of cloud databases, and the need to ensure connections are secure, Microsoft decided it was time for this backwards-compatibility-breaking change.

You can of course get back to the previous situation by explicitly setting the ‘encrypt’ option to ‘false’.

"server=exampleserver;database=ExampleDB;integrated security=True;Encrypt=False"

But a better solution is to enable encrypted connections to the database.

Debug your .NET 8 code more efficiently

.NET 8 introduces a lot of debugging improvements. If you take a look for example at the HttpContext , you see that you get a much better debug summary than in .NET 7: .NET 7: .NET 8: But that is not a feature I want to bring under your attention. After recently updating my Visual Studio version, I noticed the following announcement among the list of new Visual Studio features: That is great news! This means that you can debug your .NET 8 applications without a big performance impact on the rest of your code. The only thing we need to do is to disable the Just My Code option in Visual Studio: If we now try to debug a referenced release binary, only the relevant parts are decompiled without impacting the other code: More information Debugging Enhancements in .NET 8 - .NET Blog (microsoft.com)
