I am receiving an error when I run my code sample

The code sample provided for you is 100% complete and ready to go. You should not need to edit it in any way.

However, if you are still receiving an error, check the following:

Make sure you installed the SDK.
If the error message relates to a missing library or a file that cannot be found, return to Step 2 on the Making a Simple API Call page and follow the instructions for your preferred programming language to properly install the RingCentral SDK.

Using c#, I followed the instructions for .net 2.1 and Nuget package RingCentral,net 4.1.0

The sample code given by the website will not compile.

The error is on this line of code

restClient.Authorize(JWT_TOKEN).Wait();

Error (active) CS1503 Argument 1: cannot convert from 'string' to 'RingCentral.GetTokenRequest' RingDemo C:\Users\joels\source\repos\RingDemo\RingDemo\Pages\Contact.cshtml.cs 39

Please try this sample code

That worked,

The problem was that I followed the instructions for creating a new Visual Studio project which say to use .NET 2.1 and RingCentral 4.1.0.

I created a new project with .netcore 8 and it works.

Can you update the web page instruction which currently say this

Create a Visual Studio project

Choose Console Application .Net Core -> App
Select Target Framework .NET Core 2.1
Enter project name "Call_Ringout"
Add NuGet package RingCentral.Net (4.1.0) SDK

It should work with Core 2.1 and above. At least 2.1 is what I am using. I think the new SDK does not like this way of calling asynchronous function.

restClient.Authorize(JWT_TOKEN).Wait();

Function is now Task and called differently.

await restClient.Authorize("RC_USER_JWT");
await call_ringout();
