Hello,<br />
are you using a third party tool or dll or unmanaged code (like c) somewhere?<br />
If this is the case, then I think the problem can be related with the unmanaged code.

is it not necessary to abort the started thread?

<div>
As far as I know, if the thread completes, there is no need to abort it.<br />
In fact, aborting a thread is usable in a few cases and it is done on a purpose, not for every thread.

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.
