Description

Package restore doesn't work in Visual Studio 2017 Community.

Steps to recreate

1. If packman.json doesn't exist, add any client-side library and save the manifest.
2. Right-click packman.json
3. Click Restore Package
4. Look in output window for Client-Side Package Installer

Current behavior

13/03/2017 6:06:24 PM: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.JSON.Core, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Expected behavior

It should restore the files/packages listed in packman.json.

I am also getting the same error when trying to perform a package restore.

Same issue here on VS 2017 Pro 15.2 (26430.13)

Tried manually adding Microsoft.JSON.Core to my project but its not available: https://www.nuget.org/packages?q=Microsoft.JSON.Core

I'm facing the exact same issue on Visual Studio 2017 Community 15.3.4 with client side library installer version 1.2.130.

I enabled logging and got the following output

Trying to restore a second time I got this log file

Alright this is how I fixed it myself @madskristensen Can you verify if I did the right thing?

Open your devenv.exe.config found at this path _C:\Users\ARHAZ\AppData\Local\Microsoft\VisualStudio\15.01f228c9d\devenv.exe.config

Find the entry Microsoft.JSON.Core; it will look something like this

`

`

Add a binding redirect line <bindingRedirect oldVersion="1.0.0.0-14.0.0.0" newVersion="15.0.0.0"/>

After updating it will look something like this

`

<bindingRedirect oldVersion="1.0.0.0-14.0.0.0" newVersion="15.0.0.0"/>

`

Save your file and restart Visual Studio.

Try restoring, it should work. Worked for me.

[jc-stevens]

Thanks! That worked for me too!

[ibrahimbensalah]

Worked for me too, although I am using a subtle change of the redirect tag: <bindingRedirect oldVersion="1.0.0.0-15.0.0.0" newVersion="15.0.0.0"/>

[Bartmax]

The fix worked for me. 👍 Thanks @hamzaahmedzia1
