Check these two lines:

C#

string Url = "http://localhost:14316/api/employee";
var uri = new Uri(string.Format(Url, Id));

Are you missing something? What effect does the Id have here? Your api request does not contain any Id. So, I assume it is therefore not finding any matching api signature.

Also, async function needs await keyword.

Solution 1

I think the problem here is the await keyword is not used with async. Please change line

C#

var response = client.DeleteAsync(uri).Result;

to

C#

var response = await client.DeleteAsync(uri).Result;

As asynchronous calls are used, we should use await keyword
