问题 I've an MVC Intranet app that I've recently upgraded from .Net 4 to 4.6.1. This app queries user details from Active Directory to load details that aren't available in the Controller's User.Identity property and until lately has done so flawlessly.

问题 WPF, Excel AddIn, C#, I have multiple asychronous calls to get data from web service on main thread, then in call back, I will plot the data in Excel. I tracked call back and they run on main thread, too. but I still get COMException 0x800AC472, googled and it seems this is a multi-thread issue. but I am confused why this happened.

问题 I have to parallelize an application; This application has to process a file, I used tasks and each thread is processing one line of data (previously it used to process lines one by one sequentially). The problem is that the data provider uses some sort of caching and also it accesses the file multiple times during the process, so using one data provider was a hard work of making it thread-safe, instead I created on new data provider for each time a thread is processing a line. It works fine
