Version conflict trying to install the AuthTokens package

[sayanghosh123]

Just trying to add the AuthTokens nuget package from a new Function created using VS 2017 to use the Auth bindings from the function code. Running the command - install-package Microsoft.Azure.WebJobs.Extensions.AuthTokens -Version 1.0.0-beta3

Getting this error -

install-package : NU1107: Version conflict detected for Microsoft.Azure.WebJobs. Reference the package directly from the project to resolve this issue. MSGraphExplorer -> Microsoft.Azure.WebJobs.Extensions.AuthTokens 1.0.0-beta3 -> Microsoft.Azure.WebJobs (>= 3.0.0-beta5) MSGraphExplorer -> Microsoft.NET.Sdk.Functions 1.0.13 -> Microsoft.Azure.WebJobs (>= 2.2.0 && < 2.3.0).

install-package : Package restore failed. Rolling back package changes for 'MSGraphExplorer'. At line:1 char:1

The error does look legit. Is there a workaround to these? I have validated that "Azure Functions and Web Job Tools" extensions is up to date....

It looks like the requirements for Microsoft.NET.Sdk.Functions 1.0.13 are its .NET 4.6 requirements. This makes me think that your function application is a Functions V1 project, as it is pulling from full framework instead of .NET Core. Make sure to change your function application is a V2 project, and it should start relying on the .NET Standard requirements.

Note that the Microsoft Graph extension is only compatible with Functions V2.

That did the trick. Sorry was a silly question, I should have checked. Closing the issue now. Thanks @ConnorMcMahon
