I don't know who should get credit for this. &nbsp;My problem was the loss of the reference to that library. I don't know how the reference got deleted. &nbsp;I managed to integrate it back.

Hi,<br />
After programming (VS 2010 C#) for many hours in which the program compiled correctly, I now get this error msg:<br />

<div class="indent">
The type or namespace name 'AxWMPLib' could not be found (are you missing a using directive or an assembly reference?)
</div>
<br />
So, I removed the WMPLib and added it again to the project. I still get the error and connot compile. <br />
<br />
Does this sound familiar to anyone?<br />
Thanks,<br />
Karl

Namespace of 'AxWMPLib'  missing

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).

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
