single-tenant

I need some help, please. I know it is a long shot. I need every hotel to be its own db, but not to create a new db. At the moment when I create a new hotel, it creates the same database. Is there a way to do it properly? I would love some guidance or ideas. I appreciate any help you can provide.

Dapper - Unit of work between 2 repositories

I need to keep a common transaction between 2 repositories, but I'm not sure who will be responsible for rolling it back in case of failure. Those 2 repositories do share connection and transaction via parent, but one of them has to commit the transaction. How do people usually go about this? - Do I make it so that the service is responsible for coordinating the repositories? I'm too new but this sounds wrong because a transaction commit/rollback is the responsibility of the database layer....

NUnit, Dependency Injection, Hosting

Now that NUnit supports the new testing platform bits, I was wondering...would it be possible (or is it already supported) to do DI/IoC with test classes? My idea is this: I create a host in my entry point (which would require turning off the entry point that's automatically generated, and I'm not sure if that's a good idea or not), do all my service registrations and whatnot, and then, in my test, I can have these services injected and use them in my tests. This is primarily for integration or end-to-end testing scenarios....

✅ which .net version should I be starting with?

i downloaded the latest version from the dotnet website, 9.0, and attempted to use this -> https://github.com/gui-cs/Terminal.Gui to build out a simple console app with a TUI, but I got an error saying that i need to be on .net 6, which is marked as end-of-support. is it fine to stick with 9.0, or should I roll back to 8.0? its not terribly important that I be able to use Terminal.Gui, I just don't want to be locked out of using other libraries because the version of .net i'm using is too new....

SourceLink with private, authentication-required repo

Been trying to get this to work off and on for many months at this point, so hoping I'm missing something. We've got a number of new NuGet packages on a privately-hosted BitBucket server. They're configured with SourceLink support. When using Resharper, we can navigate into the source code of the packages after providing user credentials as shown. However, Visual Studio's native SourceLink integration doesn't seem to be able to comprehend the authentication portion of it. Whether I'm using the Git Credential Manager fallback or not, any attempt to debug into the same packages fails with a "Source Link authentication failed" error. There's an Authenticate button on the error screen, but it does nothing (i.e. the button can be clicked, but there's no popup or other control displayed). I'm running out of things to try, and really need this to work to meet our developers' needs. Git credentials are stored in the Windows Credential Manager, and work properly in git natively. Interestingly, if I try to open the SourceLink URL in the error through a Windows File Open dialog, it presents a Windows Security popup that allows me to enter credentials, but my domain credentials (used for normal BitBucket access) are never accepted, no matter which variant I try. Opening the same URL in a browser immediately downloads the file, as I've logged into BitBucket via the browser and therefore have appropriate session cookies in place....
