An assembly specified in the application dependencies manifest was not found

From @wh1t3cAt1k on March 20, 2018 18:38

Steps to reproduce

• Unpack the following project in VS Code: CoreRestaurants.zip
• cd into the directory
• dotnet build
• dotnet ef dbcontext list

Expected behavior

I see the dbcontexts list or a meaningful error.

Actual behavior

I see an obscure error

Error:
  An assembly specified in the application dependencies manifest (CoreRestaurants.deps.json) was not found:
    package: 'CoreRestaurants', version: '1.0.0'
    path: 'CoreRestaurants.dll'

Workaround

It took me 2 days to figure out that the problem might be in access rights, and running the above stuff with sudo fixes the issue.

In hindsight it is surprising how I didn’t guess it from the outset, but hey, everything is obvious in hindsight.

My point is that the error could be more descriptive so that people spend less time figuring out what went wrong. Perhaps there should be additional explicit checks made by the tool.

Note: the same issue with dotnet ef migrations list.

Environment data

I into the ~/Projects/CoreRestaurants folder.

I run Mac OS 10.13.2 (17C88).

Just a comment for whoever is having this problem on VS2017. I was running the Scaffold-DbContext from nuget package manager console and was getting the error “An assembly specified in the application dependencies manifest (WhateverProjectName.deps.json) was not found”. If you’re running this command for another project in a solution (most likely a library) you have to ensure the startup project is the one you are running the Scaffold-DbContext command for. Just choosing the Default project on nuget package manager is not enough.
