How to change the content type of an HTTP request for a FLURL client?

Question

I use flurl to send an HTTP request and this is very useful. Now I need to change the Content-Type header for some requests "application / json; odata = verbose

    public async Task<Job> AddJob()
    {

        var flurlClient = GetBaseUrlForGetOperations("Jobs").WithHeader("Content-Type", "application/json;odata=verbose");
        return await flurlClient.PostJsonAsync(new
        {
            //Some parameters here which are not the problem since tested with Postman

        }).ReceiveJson<Job>();
    }

    private IFlurlClient GetBaseUrlForOperations(string resource)
    {
        var url = _azureApiUrl
            .AppendPathSegment("api")
            .AppendPathSegment(resource)
            .WithOAuthBearerToken(AzureAuthentication.AccessToken)
            .WithHeader("x-ms-version", "2.11")
            .WithHeader("Accept", "application/json");
        return url;
    }

You can see how I tried to add the title above ( .WithHeader("Content-Type", "application/json;odata=verbose"))

Unfortunately, this gives me the following error:

"InvalidOperationException: invalid header name. Headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects."

I also tried flurl "ConfigureHttpClient", but could not find how / where to set the content type header.

, ( , ), . :

        var jobInJson = JsonConvert.SerializeObject(job);
        var json = new StringContent(jobInJson, Encoding.UTF8);
        json.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json; odata=verbose");

        var flurClient = GetBaseUrlForOperations("Jobs");

        return await flurClient.PostAsync(json).ReceiveJson<Job>();

. (2.0 ), .

, , API- System.Net.Http . -, , raw HTTP ( , , ). Flurl WithHeader HttpRequestMessage, Content-Type, , , HttpContent.

API- , Flurl , , :

return await GetBaseUrlForGetOperations("Jobs")
    .ConfigureHttpClient(c => c.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json;odata=verbose"))
    .PostJsonAsync(new { ... })
    .ReceiveJson<Job>();

Flurl AddHeader(s) TryAddWithoutValidation .
