How to synchronously call async method from quartz schedule job

Question

I am trying to call a webapi method from my quartz.net schedule job. I am not sure whether the way I am doing is right? Can anyone help if this is the right way or is there any better approach available?

MethodRepository.cs

public async Task<IEnumerable<ResultClass>> GetResult(string queryCriteria)
{
    return await _httpClient.Get(queryCriteria);
}

Quartz job:

public async void Execute(IJobExecutionContext context)
{
    var results= await _repo.GetResult();
}

generic Httpclient :

public async Task<IEnumerable<T>> Get(string queryCriteria)
{
    _addressSuffix = _addressSuffix + queryCriteria;
    var responseMessage = await _httpClient.GetAsync(_addressSuffix);
    responseMessage.EnsureSuccessStatusCode();
    return await responseMessage.Content.ReadAsAsync<IEnumerable<T>>();
}

But the quartz documentation says I can't use async method in a quartz job. How can one the Web API method then?

Can I change the quartz job execute method as:

public void Execute(IJobExecutionContext context)
{
    var result = _repo.GetResult().Result;
}

Answer 1

Quartz.NET 3.0 supports async/await out of the box. So you can (and must) now declare Execute method as Task returning and you can use async/await.

public async Task Execute(IJobExecutionContext context)
{
    var result = await _repo.GetResult();
}
