Is it possible that your app is 64-bit and that library is only available in 32-bit format? Try target x86 instead of Any CPU or else check Prefer 32-bit and see whether the issue goes away. — jmcilhinney
using x86 it shows the same error but this time with "System.Fabric" — Youssef El Basraoui
Are you creating a .NET Core application and trying to reference a .NET Framework DLL? Is it maybe for an older version of .NET? I'm not sure what error message you'd get in those cases. — jmcilhinney
yes,I'm trying to debug a website project written in asp.net that have a lot of references to other DLL's — Youssef El Basraoui

'System.Fabric' packages are x64 bit, if your system target 32bit it will fail.

So fix the error...

Bulid the platform into x64 bit.

You have install Nodejs Azure Functions Core Tools from NODC.

For Download Refer this link.. https://nodejs.org/en/

After installion, in Command Prompt input npm i -g azure-functions-core-tools --unsafe-perm true So, You azure-functions is permission is enable..

After this, follow the below step....

Then set project debug properties(right click on your project>Properties>Debug blade).
Set Launch type to Executable
Set Executable path to %appdata%\npm\node_modules\azure-functions-core-tools\bin\func.exe.
Add Application arguments start.
