I have recently started working on an already existing .net project but I am facing problems with building it as it keep facing an “Unable to find package” errors.
Here is a picture of the errors:

I have already placed these packages where I should place them but it didn’t work.

I have placed a packages folder in the main solution directory and added it to the package manager settings as shown below:

But this didn’t fix the issue as I am still getting the same type of errors.

Can someone assist in fixing this issue and suggest what I can do?

Thank you.
