Resolution: Context Switch Deadlock was detected !!!

When I debug my solution which has an implementation of exporting data in a data set into an excel work book (while looping through the data set) it gives the following error in VS IDE,

The CLR has been unable to transition from COM context 0x4c4b68 to COM context 0x4c4cd8 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.

 

 

 

 

 

 

 

 

 

 

 

Get visible missing templates in Visual Studio

When I attempted to add a web site to my existing solution file, I experienced that the Add New/Existing Web Site option in the context menu was not there. I’ve done this before and I’m pretty much sure this is a strange behavior of VS 2010 IDE.

I tried from re-starting VS 2010 to rebooting the machine. Unfortunately, nothing worked for me. So, I had some crazy idea to re-install VS. Luckily, my mind drew into do a web search whether somebody has previously experienced this weird behavior. Fortunately, I found a solution through a blog post written by chiragrdarji to get visible all the missing templates. This approach saved me a lot of time in re-installing the VS once again. 🙂

The only thing that you need to do is to open a Visual Studio Command Prompt and run the following command.

Before run this command, just close all your Visual Studio instances.

devenv /installvstemplates
