deps.json file is not found in project root folder

I run the following command in Package Manager in Visual Studio 2019 and a ASP.NET Core 5 project:

Scaffold-DbContext "Server=(local);Database=MyDB;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Entities -Context ApplicationDbContext

After a little time, this error appears:

The specified deps.json [C:\WorkingFolder\Projects\MyProject\MyProject.deps.json] does not exist

Notice that the deps.json file is being searched in project root, not under bin folder such as other posts I have found here, so by deleting bin and obj folder does not help.

How to solve it?

It seems the deps file location is the problem. That file is created inside the bin folder. I have copied it in project root folder, and the error was now that the DLL was not found. So the question would be: why the deps file is being searched in the project root folder? - jstuardo
This only started happening to me this week. I have a new .NET 5.0 Blazor project I was going to start and I can't get passed this. What was your solution? - Eric

I am able to solve the same issue by setting the project contains the EF core files as a startup project.

Same problem: VS 2019 16.10.3 Professional

Add-Migration init
Build started...
Build succeeded.

The specified deps.json [C:\Users\USER\source\repos\FirstAspCore\FirstAspCore\FirstAspCore.deps.json] does not exist

Attempted Solution 1:

Copied the FirstAspCore.deps.json located at the bin/debug/netcore3.1 to the root

Build succeeded.

It was not possible to find any compatible framework version

The framework 'Microsoft.NETCore.App', version '2.0.0' was not found.

The following frameworks were found:
 3.1.16 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  5.0.0 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
  5.0.7 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:

Attempted solution 2:

Even if u download all The frameworks 'Microsoft.NETCore.App', version '2.0.0' then will prompt for older version and u download it ,at the end will not work

Attempted Solution 3:

Copied everything from the location bin/debug and pasted in the root folder ,it is an insufficient way, but figuring out which are needed going to take time, it worked for now.

PM> Add-Migration init
Build started...
Build succeeded.
