Bits of .NET

Mixing async and blocking (.Result, .Wait()) causes deadlocks. Go async all the way!

❌ Deadlock Prone:

public void DoWork()
{
    var result = GetDataAsync().Result;  // DEADLOCK risk!
}

public async Task GetDataAsync()
{
    return await httpClient.GetFromJsonAsync(url);
}

✅ Proper Async:

public async Task DoWorkAsync()
{
    var result = await GetDataAsync();  // No blocking!
}

public async Task GetDataAsync()
{
    return await httpClient.GetFromJsonAsync(url);
}

Rule: Once you go async, stay async all the way up the call stack!
