Have you thought about applying QoS rules on the network (router)?

No, because some modem doesn't have QoS. I'm developing a new download manager and I want to decrease download speed whenever user starts using internet for opening website, listening music on spotify, gaming online or any other usages.

I was thinking on the lines of implementing it at the network level and not on the individual machines. Would seem to be a lot simpler to implement and would not be adding further load on your WiFi bandwidth

We don't have any access to Modem/Router's config and also All modems doesn't have QoS settings.

Also, I'm a developer and here is CodeProject not Superuser. I want to make application for my users not changing QoS setting for my uses.

Sometimes you need to step back and look at the big picture; if you are having a problem with bandwidth it does not make sense to me to add to the network load in an attempt to regulate it.
And the correct spot would more likely be ServerFault

I want call dll functions in thread and it uses handle object for parameter.
If I call dll functions directly, then there is no problem.
But if I call it via thread, then runtime error occurs.
I think it will be because of handle object, so I have saved handle before start thread to static variable and use this value in thread.
But the problem is same.
Please help me.

All functions are called via a thread: a Thread is the basic unit of execution for an app and if you don't have a running thread, you don't have running code. Initially, your code will have a single running thread, and when they stops executing your app is closed - but you can add threads to do long running functionality without affecting the user display, or to increase the parallelism of your processing. In broad principle, there is no difference between the original thread and any you add, except in .NET only the thread that created Controls can access them.
But ... your use of "handles" implies you are actually not working in C#, but in C or C++ so you would need to ask this in a different forum.
Either way, you'd need to give us a much better explanation of what you are doing and how it is going wrong that you have: Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

What runtime error are you seeing? Without this basic piece of information, any help will be guesswork at best.

What do your "calls" look like? You're implying you have 2 different ones.

Today, out of nowhere, I started getting this error when I run my app
System.ComponentModel.Composition.ImportCardinalityMismatchException: No exports were found that match the constraint:
ContractName Views.MainWindow
RequiredTypeIdentity Views.MainWindow
I have made NO code changes. One minute it was running fine, the next - bam! error.
ALl of the Google search hits I found talk about some kind of Visual Studio problem, but this only happens when I RUN my app, not open it. And, the message sure smells like EntityFramework, which we're using.
The message mentions "ImportCardinalityMismatchException". Never seen this before.
I following the instructions in this SO post, I repaired VS, rebooted, and all that.
Anyone have any thoughts on this?

Google points to MEF, not EF.

Any plugins loaded when the app runs?

..and unless you have a hash from all libraries that your code uses, it is hard to prove that "nothing changed".

So you're using MEF?
Did it "stop working" at the exact same time on other machines? Do you have yesterdays backup that you can try in a VM?

You're hopeless.
It is a Microsoft error. However the resolution is this:
Clear the Visual Studio Component Model Cache. Delete or rename this folder:
%LocalAppData%\Microsoft\VisualStudio\11.0\ComponentModelCache
or
%LocalAppData%\Microsoft\VPDExpress\11.0\ComponentModelCache
and restart Visual Studio. The issue will have been resolved.

I could go on, but it's "hopeless".
The fact your "turn-around" time was so short, you:
a) didn't read it
b) and can't be bothered

I spent 2 days researching this Google hits are all about some kind of VS problem.
So let's just assume that you're here to troll, and not help, so unless you have a serious response... don't.
if you dont have a solution to the problem, dont reply

You think your snotty replies should go unchallenged? No problem in the future.

So I'm not sure why you took my responses the way you did, as I certainly didn't mean any offense.

Not the first time you utter that accusation.
In the previous thread you keep hammering on the idea that nothing changed; in which case, the output and behaviour would be the same still, so evidently, something changed. Most of the stuff I read keeps pointing to a change in VS MEF by NuGet, and you stated it only happens on your machine.
So you broke your dev-environment; if you don't have the patience to evaluate suggestions, your best course of action is to rebuild a clean dev-environment. I'd first be trying to get rid of anything MEF-related and redownload only the stuff that's needed.
That is, without using NuGet for anything, and installing stuff by hand so you can control exactly what is installed.

I didn't mean to offend anyone. But as I said in my OP, I tried the Google result suggestions. None of what worked. Those posts all say that when VS was opened, the error occured. That's not what's happening here. I can open VS and run other apps with no issues.
It's just this one app that throws this, and only when I RUN the app, not open it.
And As I said before nothing changed. Literally NOTHING. At least in VS or the code. I was working Friday afternoon. Monday morning this started. I guess some Windows update could have been applied. But what Windows update would only affect THIS app?? So I serioualy doubt I 'broke' my dev environment.
If it's not broken, fix it until it is.
