Couldn't instantiate proxy of class

[Tiago Noronha]

Hey, i'm giving the nuget package a try and encountered this exception, was it something I did on my side?

[huysentruitw]

Can I see the DefaultOptions declaration?

[Tiago Noronha]

It's the same as the readme:

public DbContextOptions DefaultOptions{ get; } = new DbContextOptionsBuilder().Options;

[huysentruitw]

Can you try public DbContextOptions<PlantsContext> DefaultOptions{ get; } = new DbContextOptionsBuilder<PlantsContext>().Options; ?

(DbContextOptions cannot be casted to DbContextOptions<PlantsContext>)

[Tiago Noronha]

Yep it worked! But shouldn't the object returned from the service.GetAll() (which basically returns Plant.AsEnumerable() be of type IEnumerable?

I'm getting it as an DBSet I believe..

[huysentruitw]

You'll need to post more context I'm afraid

[Tiago Noronha]

I can do you one better, I can give you a sample project.

Try running the test Plants_GetAll_RetunsNull on this branch: https://github.com/tiagodenoronha/PlantsIdentifier/tree/feature/testProject

[huysentruitw]

When changing AsEnumerable() in the service to ToArray(), it seems to work, so I'll have to dig into the source, probably something needed for the extension method AsEnumerable() is just not mapped.

For the test Plants_GetAll_ReturnsOk, you also need to initialize the DbSet:

dbContextMock.CreateDbSetMock(x => x.Plant);

[Tiago Noronha]

Hmm gotcha, i'll change the method to ToArray for now :)

The first test I hadn't tried it yet :b
I'll close this issue and open up a new one with "Map AsEnumerable" so you can track it better.
