Asp.Net 5 Nuget软件包错误

Question

I added VNext class library to ASp.Net 5 project, and I'm trying to add Nuget package "Npsql":

But it can't compile, what I'm doing wrong?

Answer 1

The problem is that when you add the dependency to all TFMs ( dnx451 and dnxcore50 ). Mostly sure, Npgsql doesn't support dnxcore50 (CoreCLR).

You have 3 solutions:

1. Remove dnxcore50 completely
2. Move the dependency under dnx451
3. Use #if DNX451 conditional compilation blocks in your code
