getting tcp connection state

im currently in following situation: we have a tcp architecture where more or less everything can connect to (local network). since devices conencting arent always behaving properly we cannot bet on graceful connection closing. as a workaround we are polling on IPGlobalProperties.GetActiveTcpConnections to forceclose connections and require a new handshake and datasyncing. we have the problem now though that with increasing amount of tcp sockets in windows (checked via netstat) that call gets rediculous slow and cpu heavy. more or less all i need is to check that the connection that is/was connected is still estabished. are there any alternatives i could use? would p-invoking GetTcpTable be faster? are there better apis?...

Why is `dotnet publish` not including Roslyn for my ASP.NET Framework 4.8.1 Web App?

I converted my .NET Framework 4.8.1 Web Application to SDK-style projects (like Microsoft recommended). I think I've worked out all of the quirks except for the publish piece. For some reason, the publish likes to modify my web.config and add stuff to it not included in the original. It also is not including the roslyn folder in the bin folder in the published output. ANYWAY. I worked around the web.config getting molested. Now I just (I think) need to find a way to include the bin\roslyn folder in the published output....

Selenium-unable to find element

Trying to run TestLogin(1st test) inside TestAddToCart(2nd test) then find an element afterwards, but unable to. I was able to find the element in the first test, but it doesn't seem to work in 2nd test. Not sure if it is allowed or there needs to be some kind of wait time. [Test] public void TestLogin() {...

I'm getting this weird error here. Probably some namespace wizardry i'm not aware of.
