KeyVaultClient.GetSecretAsync(url) causing delay

Radhakrishnan 1

We are using Azure KeyVault to store certain back end credentials that our Azure API uses to query. The GetSecretAsync call always takes at least 15 seconds to return. Is there any way to speed up this call. Below is the code used.

KeyVaultClient kvClient = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(TokenBasedAccessHelper.GetToken));    
var secret = Task.Run(async () => await kvClient.GetSecretAsync(url)).Result;
return secret.Value

Just curious but why are you using Task.Run and .Result instead of awaiting directly GetSecretAsync ? It seems weird.

Thanks for asking question! There is a common deadlock issue as the call never returns and the query hangs indefinitely. Also, If you’re in a non-async method, its let you use .Result

You may refer to blog Don't Block on Async Code might be helpful.
