Hi Martin,

I'm not sure I understand your question completely. Have you made your own WebApi controller or are you trying to use the HttpClient inside a Razor template?

If you have made your own controller, you can make an async action like this:

    [Route("asynctest")]
    [HttpGet]
    public async System.Threading.Tasks.Task AsyncTest()
    {
        var client = new System.Net.Http.HttpClient();
        var response = await client.GetAsync("http://dynamicweb.com");
        var content = await response.Content.ReadAsStringAsync();
        return Ok(content);
    }

If you need to use an async method inside a Razor template, you need to make is synchronous. You can do that by doing this:

    var client = new System.Net.Http.HttpClient();
    var response = client.GetAsync("http://dynamicweb.com").GetAwaiter().GetResult();
    var content = response.Content.ReadAsStringAsync().GetAwaiter().GetResult();

It's important to use GetAwaiter and GetResult instead of either .Wait or .Result as they have some strange behavior when dealing with exceptions.

I hope this helps.
