Replied by support on topic IIS stuck with high CPU in new EasyUAClient()
Unfortunately I cannot reproduce it.

Can you please provide some more information?

1. Which operating system do you use, and is it 32-bit or 64-bit?
2. Which version of Visual Studio do you use?
3. In the C# examples solution that we ship with the product, there is a very primitive "UAWebApplication1" project which just reads and displays one value. Does it also hang on 'new EasyUAClient()'?
4. Regarding subscriptions: This must be in some project, right? - because if you could not get past 'new EasyUAClient()', then the code will have no chance to actually call the SubscribeXXXX method. Can you please explain, or describe that other project.

Thank you

IIS stuck with high CPU in new EasyUAClient() was created by Fusco
Hi,
Almost same configuration for me, .NET 4.5 MVC application.

I just installed 5.35 versions and it doesn't work anymore. The instruction
static EasyUAClient easyUAClient = new EasyUAClient();
Fails. Process IIS get stuck consuming all CPU.
It worked fine with 5.34 version.

Furthermore subscriptions don't work. It looks like the callback function isn't fired.

Thank you
