Error: Object reference not set to an instance of an object

Norsten

Hello,
I am trying to create a new connection using "Entity Framework DbContext (4.1/4.2/4.3/5.0)"

When I select the assembly DLL (which shows me my DbContext) and then click Test (or OK) it gives me the error "Error: Object reference not set to an instance of an object".

What does this mean (and how can I fix it) ?

(I am using v4.42.14 Premium Edition)

It's a bit hard to diagnose, based on that. Is there anything in %localappdata%\linqpad\logs\log.txt?

Don't know if this is the same thing but in v4.43.04 I get a similar exception calling PickFromList - which works fine in v4.43.00

System.NullReferenceException occurred

This should be fixed now in 4.43.05

Yep sorted, thanks
