Serialization error: Unable to find assembly 'EntityFramework

I do realize I am probably just grasping at straws, but this is a serious issue for us, and I must sort it out.

I changed the web.config as you suggested, and the site still functions. I will monitor my Application log and watch for the errors to appear again...hopefully they will not...

I don't have Visual Studio on our server, but I was able to get the properties for the EF in the root /bin folder:

File Description: EntityFramework
File version:  6.1.30225.0
Size:  4.93mb
Date Modified:  3/18/2014  9:36am



I began having this problem, however, with version 3.20 of nopcommerce, and a previous version of the EF:

File version:  6.0.21010.0
Size:  4.81mb
Date Modified:  10/17/2013  5:19am

Thanks,
Steve

I never tried registering the EF into the GAC while I was running 3.20...I had been optimistic that the upgrade would cause the serialization errors to cease..

I used gacutil.exe and registered the one located in the 3.30 site installation /bin directory into the GAC.

That action might have solved the problem (not sure), but it caused the fault on my development site and I had to use gacutil.exe again to unregister it. I verified again, there is now no EntityFramework.dll registered in my GAC.

This was basically a brand new Windows 2008 server installation, so I really doubt that the EF had already been registered by any other software/assemblies prior to my attempt at registering it...

Strange....

Hi Steve,

How is it going? Any errors?

14 hours now with no errors....it is hard to be optimistic at this point, but I remain hopeful!

Great! Please write back about the progress in a couple of day

No joy...within about 4 hours of my last post, I had the familiar 3 errors occur again...
However....this time, they were immediately preceded (within 3 seconds) by two other errors and a warning that I have never seen before:

I have determined that our smartertrack support site threw the first 2 errors...not the nopcommerce site...(but the warning was on the nopC site's processID)...but it seems like more than just a coincidence that they would occur immediately before the familiar 3 errors...though I am still clueless as to how to fix it..

I don't think that it's somehow related to the original question. Furthermore, I see that you're using some custom solution and tables (there's no "st_GlobalSettings" table in nopCommerce). And this error states that you're trying to insert already existing primary key into this table. Maybe, all these errors are caused by this customization? Do you experience this error on the clean default implementation?

As I said in my previous post, the first 2 errors actually were thrown by my smartertrack support website's process ID, but those 2 errors, the warning and the original 3 errors all happened within a few seconds, which seems unlikely unless related....

Same problem here. Have no clue what is going on. I see this in my Event logs:

"Autogrow of file 'nop_jevell_log' in database 'nop_jevell' was cancelled by user or timed out after 31043 milliseconds.  Use ALTER DATABASE to set a smaller FILEGROWTH value for this file or to explicitly set a new file size."


Um... My log file is like 2 megs and 400 columns, not like very big.......

OK, Steve, just recreating the application pool fixed the problem like you said.

Is this a Microsoft bug?
