Linqpad 6 - EfCore driver not working

davidroth

Hi,

first of all congrats for the V6 release - its awesome.
I want to report a bug with the ef core driver in V6.
I have tested it against a 2.2 Version of EFCore and a 3.0-Preview version. Both versions are not working when using the DBContextOptions constructor:



Linqpad 6 correctly recognizes the ctor, but it does not work (Neither when clicking "Test", nor when clicking "OK")

There seems to be a bug where it can't pick up protected constructors. For now, you can work around it by making your constructor public.

Hmm, there must be another issue because my constructor is aready public:

This could be tricky to diagnose. Could you first try running the following build:
https://www.linqpad.net/GetFile.aspx?experimental+LINQPad6-Beta.zip

and let me know if it makes any difference?

davidroth

I get the same error using the build from your link.

JoeAlbahari

Do you get the same error with the parameterless constructor or the one that accepts a string? Click the "Help me decide" link for an example on how to set these up.

I've just uploaded a new build here which will log more details of the problem:
https://www.linqpad.net/GetFile.aspx?experimental+LINQPad6-Beta.zip

After it fails, go to %localappdata%\linqpad\logs.linqpad6 and send me the most recent entries in log.txt

Thanks

I have successfully tested it with your latest build, no issues any more - thanks!

JoeAlbahari

Terrific. I'll push out the new beta.

davidroth

Thanks.
Fyi: I just tried the updater (help => check for update) and I got the following error dialog when updating to the latest version:



However, the update seems to have worked.

JoeAlbahari

It looks like I need to ship both X86 and X64 versions of the update patcher.

It will work in spite of the error because it can run the update directly from %localappdata%. It's just failing to patch the original executable, which will cause a slight startup delay.
