Just to add to this, I am having the same problem, but the error is related to a missing property on our model.

The big problem is that our model has the said property, and then at some point, the MVC system seems to indicate that the property doesn't exist.

I had a look in the source to MVC 3 RTM, and found that everything revolves around the activity in the ChildActionMVCHandler which is derived from MVCHandler and uses the base classes behaviour. None of this could be causing the fault however, so the ServerExecuteHttpHandlerAsyncWrapper is somewhat of a red herring.

I can't debug all of this, because can only find source code for MVC 3 V3.0.0.0 and V5.0.0.0 - I would love to know where I can download version 3.0.20105, if anyone has any clue as to where to get the source code, I may be able to get to the bottom of the Framework or Environment issues that cause this intermittent error.

[UPDATE] I altered my code so that I was using @Html.Partial instead of @Html.Action - then I cleared the view file and called without a model reference, all whilst the prevailing (permanent until app recycle) condition is happening.

I have found that I still get the error that a "CategoryNavigationModel.get_subCategories" is missing, even though the view file is empty, and references no strongly typed model. This means that the MVC framework has stuck in so far as this file is concerned, and no longer recompiles it.

I can't debug through the call to @Html.Partial, so I really can't track this fault down. Any help with it's solution would be very much appreciated. Including how I can debug it.

Hi,

I've just come in to work this morning, and found that the error still exists despite refactoring my code.

Last week, I presumed that intrinsic difficulties in performing @Html.Action may be to blame, so I put all of my backend logic into a Plain old class and used it's methods from my RAZOR script. This allowed me to change the code to a @Html.Partial.

My Class was called CategoryNavigationTools. The error is now pure and simple - Could not load type 'Nop.IA.CategoryNavigationTools' from assembly 'Nop.Web, Version=2.6.5.0'.

By by reckoning, this means that part of the type information has become either unloaded, or otherwise masked from the RAZOR compilation process.

How is this possible? Maybe the plugin manager? (but this isn't a plugin)

How can I find out which bit of my code might be triggering craziness in the RAZOR compiler?

Hi,

I have found out what the problem is with our NopCommerce 2.65

In short, our plugins were outputting all of their references into their Plugin folder, and the Plugin Manager was loading them all.

In effect, because we had registered Nop.Web, and then continued to customise the real Nop.Web, the version in our plugin folder ran out of kilter and lacked any of our customisations.

It appears that Razor prefers to use the version loaded by the plugin manager, and this explains all of the problems that we had. Our solution is now stable and quick.

Hope this helps someone with a similar problem.

I activated one of the " Shipping Rate Computation Methods" after that it worked

Hi,

I've a problem a little bit similar.
When I deploy my project, there is no problem.
But, after some hours without any change, some functions are unavailable from my Nop.Services.dll (this new functionality coded by me work well before)

If I download the Nop.Web.dll, and re-upload it, it works again !
But in few hours, it's going to crash again.

I've already have this problem with the Nop.Framework.dll. I've added an entityName in the GetRouteData, it work well, and few hours later, it crashes ...

I've take a look at my "bin/" folder in the "Plugins" folder, like mrabjohn suggest it, but there is no Nop.Services.dll and no Nop.Framework.dll

Any idea ?
Thanks

plugins are only temporarily copied to Plugins/bin, I think. If you are having issues with plugins copying references, the offending dlls would be in the plugins folders. For example, Plugins/MyPlugin/offending.dll

Yeah.

I've made my own plugins.

So its reference made copy in local /bin/folder. So the Nop.Services.dll and Nop.framework.dll where too old to work with my newcode.

Thx

Placing @using Nop.Web.Framework; inside a custom view solved this problem for me.
