Hi Jens Birk,

Forget to tell, you need to have net connection turned on to download packages from internet. If still its not working try downloading NewtonSoft directly from

https://github.com/JamesNK/Newtonsoft.Json/releases.

Unzip the downloaded file & copy Newtonsoft.Json.dll from the folder that matches your project Framework version & coy to the desired folder (namely lib in your project). Add a manual project reference to Newtonsoft.Json.dll & compile...

You can resolve this issue in two ways

Option 1

Tools-> NuGet Package Manager -> Package Manager Settings General
Check "Allow NuGet to download missing packages" &
Also check "Automaticall check for missing packages during build in Visual Studio"

Option 2

1. View\Other Windows\Package Manager Console
2. If your solution has only one project skip this step else In "Default Project" Select the project which in which error occurs
3. In PM> type "install-package Newtonsoft.Json"

Issue will be resolved.

Thanks for sendilg's reply.

Hi Jens Birk,

Please try sednilg's suggestion first. If that doesn't work, then please create a new blank project to check whether the new project also has the same problem.

If the problem just occurs with this specific project, please tell us which project type you created and share some code snipped to help us reproduce this problem.

If this problem occurs with all projects, please try with following steps to troubleshoot this problem.

1. Run Visual Studio as administrator.
2. Close all third part software, such as antivirus.
3. Reset all settings by menu Tools -> Import and Export settings -> Reset all settings.
4. Repair your Visual Studio.

Best Regards,
