I have not tried Ipfs.Core with Xamarin. Could you please give the errors?

Does Xamarin support .Net Standard 2? Have you read https://dzone.com/articles/xamarin-forms-and-net-standard-getting-started?

This may also help https://docs.microsoft.com/en-us/xamarin/xamarin-forms/internals/net-standard

Also, are you trying to add ipfs.core of ipfs.api? Please raise individual issues, my mind only has a few slots for issues.

If you have repo with the project, I'll fork it and try to get it to work.

@richardschneider Thanks for help.can you please tell me...How to wrap data in Merkle Dag with xamarin forms or c#.?I need to add content to ipfs network.Before that i want hash value for the content.Now i can get hash values of raw data but when we add content to ipfs it wrap the data with merkle dag then create hash value of the content before uploading to ipfs n/w.

The easy way is to simply call FileSystem.AddFileAsync. It returns a FileSystemNode which contains the Id. The ID is a CID (Content ID) which in the normal case, v0, is the multihash.

using Ipfs.Api;

var ipfs = new IpfsClient();
var path = "path-to-file";
var node = await ipfs.FileSystem.AddFileAsync(path);
var hash = (string)node.Id;
Console.WriteLine($"The hash is {hash}");

Please show what IPFS addreturns and what the above code prints. Also please attach the image.

The new documentation on the client and the file system may help.
