Goodies | Useful stuff missing from .NET for example duck

I have used toolbar for search option but what I am unable to understand is how to get the search menu inside toolbar second line like this below.

I have used SearchDialog and done it but it comes like below.

[2

but its overlapping like this

Do I have to use collapse bar? Have tried both SearchView and SearchDialog but not sure how to get above result.

Here is my toolbar xml code.

I have 3rd party WebSocket that I need to consume where the request is sent in one method and the response is given in another. How can I convert this type of pattern to a more typical async/await TPL Task that will support cancellation (via token), continue with and all the other goodies.

This is what I came up with so far, although I'm not sure if it works. I can't test it until Monday.

So here are my questions:

1. Will this work?

2. I've been reading about TaskCompletionSource. Is there a better way to do any of this possibly with TaskCompletionSource?

3. I really don't like the lock because I know it has the potential to block for a long time but but I'm not sure how to do it any better because if I don't lock a second call to AsyncGetPositions could clear any positions already returned.

4. Even with the lock I know that if there is a timeout or cancellation that creates a problem so maybe I just remove the cancellation token. The only other thing I can think of would be to create multiple clients that are all authenticated and ready to process a request and then manage them like a thread pool for these types of request but I'm not going to be doing that anytime soon so other than that... idk.

I'm trying to compile a minimal example of .NET C++ code (just calling CLRCreateInstance and starting a CLR runtime host). I'm not using Visual Studio, but mingw. I installed the Windows 10 SDK with .NET goodies, and I have the header and lib files correctly installed in Program Files. However, I cannot get g++ to link my program:

I've took values from a Json file which containes values as :

I'm looking for some general information on how to secure my backend running on AWS. I have mobile apps that send requests to PHP scripts living in AWS EC2 instance configured with NGINX. Only thing PHP scripts do is querying MySQL database and echo the json response back to the app. I was looking for options to enhance security of the backend against DDoS attacks and such. I do not have any web contents the users can interact with but just these PHP endpoints which apps communicate with to retrieve data.

1. In my case, will AWS Cloudfront be helpful? As far as I understand, CloudFront is for CDN, which deals with static web contents that can be distributed to different servers, but since I don't have any websites, and the PHP files are just serving data back to the mobile apps, I'm not sure how it can help.

2. Also they say AWS Shield is enabled by default, but I'm not sure if that's only useful if I use AWS-API they provide as a service rather than me just having php scripts uploaded to EC2 instance on my own.

With the way I have php files on the server, I'm wondering if my backend gets all the goodies AWS is boasting about their security in general.

I know the question is very generic but as a starter, any advice to what AWS products/options I might be able to opt-in for to make the backend more secure will be appreciated.

Thank you

I'm creating some kind of React layouting library that stores its current state in a Redux store. The library isn't just a styling thing, it has certain (for this question irrelevant) capabilities.

However, since it's a layouting library, the consumer of the library will provide what to render at certain locations.

The library would be exposed thru a single slice (with corresponding reducers, actions and selectors) that the consumer is supposed to simply inject into their root reducer.

Currently, the way the library knows what to render is by the consumer providing the rendering function.

Somehow, an .iml file has made its way into my git repo...

Here's how am I trying to get rid of it:

1. I cloned the latest version to a local folder
2. Checked out the branch that I want to merge later into master
3. Deleted myproject.iml (using windows gui)
4. edited .gitignore with extra line: *.iml
5. Trying to stage the changes: git add * -A
6. Trying to commit: git commit -m"untrack .iml file and ignore for future commits"

Problem:

In c# 9, we now (finally) have record types:

P0847 proposes the possibility of using explicit this parameter for member functions.

Among other great goodies that this proposal brings, there is also the great new possibility for CRTP without C, R and even T.

A common practice for implementing a generic clone in C++ is based on CRTP, see for example this SO post.

Given that we need clone to be virtual (or at least, behave as virtual), to allow:
