The key (which might help in search terms) is async. A quick search for async httpcontext mvc gets us to this existing question with a lot of information about async/await and HttpContext usage.

The super short version: in MVC, the HttpContext gets carried around in the thread synchronization context (which is also where, say, the culture and other thread settings are carried around) but it's expensive to cart that context from thread to thread so the default is to not do that. You need to enable it explicitly to work.

Here's a blog article explaining the various knobs you can turn in web.config to get it to work but the net result is, basically, to make sure is set (well, set that value to 4.5 or higher).

If that's already set, then... maybe there's something else at play, like a call has the ConfigureAwait(false) set on it so it's not returning to a thread context that has the HttpContext. But, more than likely, that httpRuntime flag should fix it.

QUESTION

Cosmos DB Emulator Excessive CPU usage

Asked 2022-Mar-21 at 13:30

Since upgrading to version 2.14.5 of the Cosmos DB emulator, I'm seeing high CPU usage by what appears to be the tray icon process (Microsoft.Azure.Cosmos.Emulator.exe). See below, using up most of a CPU core constantly on an Intel i9-12900K. This was an upgrade from 2.14.4 on Windows 11.

Anyone from the emulator team know what might be going on? Seems like the process is doing something silly, given the system is otherwise quiet and the process is not actually doing anything related to serving requests.

Also worth noting is that opening the "About Azure Cosmos Emulator" dialog immediately drops the CPU usage to 0. When closing the dialog, usage jumps back.

There is no built in support on Cosmos SQL API to achieve the above result. But you can implement the following suggestions

You could either write your own logic in User Defined Function or retrieve the data and format it in the way you need on the Client Side
Other way is to just include the index in the data model itself

QUESTION

Is it possible to use Entity Framework Core 6 with MongoDb?

Asked 2022-Feb-23 at 18:58

Is it possible to use EF Core 6 in combination with a MongoDb? From what I'v gathered online, I could only find answers from a few years ago that say that it's still not possible, but nothing that was published recently. There is also better support for the Azure Cosmos Db which is also a NoSql database, so maybe I could use that to communicate with a MongoDb?

If it's still not possible, what other approach should I use?

...

ANSWER

Answered 2022-Jan-07 at 08:31

There is no official MongoDb provider implementation for EF core at this time, I did not see any mention of MongoDb in the .net core 7 (the next version) roadmap as of now.

See: https://docs.microsoft.com/en-us/ef/core/providers/?tabs=dotnet-core-cli

I quickly googled a bit but could not find a recent version of a MongoDb provider.

Msdn docs also do not use EF core: https://docs.microsoft.com/en-us/aspnet/core/tutorials/first-mongo-app?view=aspnetcore-6.0&tabs=visual-studio

How to disable azure cosmos db continious backup

Asked 2022-Feb-22 at 10:59

I enabled the Azure cosmos DB continuous backup for one of my Cosmos DBs.
How can I disable it? It just says you have successfully enrolled in continuous backup.

ANSWER

Answered 2022-Feb-22 at 10:59

I am not sure if you have seen this message in the portal when you created the account/also mentioned in the doc

"You will not be able to switch between the backup policies after the account has been created"

since you need to select either "Periodic" or "Continuous" at the creation of Cosmos Account, it becomes mandatory.

Update:

You will not see the above in portal anymore, you can Switch from "Periodic" to "Continous" on an existing account and that cannot be reverted. You can read more here.

QUESTION

Dependency Injection & connection strings / Multiple instances of a singleton

Asked 2022-Feb-14 at 12:24

I have a Web Api project which relies heavily on Azure Cosmos DB. Until now, having one Cosmos DB account (one connection string) was sufficient. Now a new requirement is to be able to connect to a different Cosmos (two connection strings) depending on an incoming parameter.

For customerId X we should fetch documents from Cosmos DB 1 and for another customer Y we have to look in Cosmos DB 2.

Until now my Startup.cs file registered a singleton instance of CosmosClient. Which in turn gets instantiated like this cosmosClient = new CosmosClient(endpointUrl, primaryKey); And this worked really well. The Web Api was easily able to process all requests. But now that we have to new up a CosmosClient per request, performance is really bad.

So my question is; Is there a way to have multiple instances of the same singleton? As in; can we create a single instance of the combination Class+EndPointUrl? (Would that still be a singleton?)

Right now, we are newing up thousands of CosmosClients every minute. And we really need just one more compared to what we had earlier.

...

ANSWER

Answered 2022-Jan-31 at 09:21

There's multiple ways to do this, but an easy implementation would be to create a wrapper around each CosmosClient you use. The only use of the wrapper will be to allow you to use various instances of the CosmosClient and differentiate them by their types.

ANSWER

Answered 2022-Feb-13 at 16:24

The results of both codes differ because of two issues:

In the Go Code, the private key is derived incorrectly:

In the Python code, the path m/44'/118'/0'/0/0' is used, as the output of hdwallet.path() shows. In the Go code, in contrast, the path m/44'/118'/0'/0/0 is used, as shown by the output of path.String().

To use the path of the Python code in the Go code, the path can be e.g. specified directly. For this the line:
