When we load asm5 from the byte[], the assembly is loaded in the LoadNeither context, while the assembly containing the type for the type conversion is loaded in Default context. Once the temporary files get created, the exception will happen every time the page is requested. I have try to place a mutex on global.asax when the application starts to lock only one compile at the time, but this fails also. Type A originates from 'XXXX.XXXX.Auditing, Version=, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Users\Craig\AppData\Local\Temp\Temporary ASP.NET Files\root\5d978e5b\ffc57fe1\assembly\dl3\2b1e5f8f\102c846e_9506ca01\XXXX.XXXX.Auditing.DLL'.

Privacy statement Dev Centers Windows Office More... Other custom controls, with similar load did not have any problems. Can one bake a cake with a cooked egg instead of a raw one?

Type A originates.. If available memory is still low, the problem may persist until more memory is available in which to run the application. To clear the error state, an application pool flush / iisreset will clear out memory, and then a rebuild will usually fix the problem. and also \AppData\Local\Micorosoft\InfoPath\FormCache4...

So it happens not only when assemblies are loaded explicitly. A Cannot Be Cast To B C# I write the message to see that all is the same, is only change the compiled dll. Under the same core code runs more than one sites (something like stackexchange) and all have the same random problem. http://stackoverflow.com/questions/29978888/type-a-dll-cannot-be-cast-to-type-b-dll-type-a-originates-from-in-the-context Maybe at some point it should get addressed :) share|improve this answer edited Mar 7 '13 at 19:00 answered Mar 6 '13 at 17:13 David Ebbo 22.2k34064 I check

BinaryFormatter includes the type metadata in the serialization, which means that only the exact same assembly will do. 2 solutions: put this type in a dll, and reference that single dll So the compiler punts and compiles DupedControl.ascx into its own separate assembly first.

if yes , revert all the changes back before this started and look carefully at the code and which models/controls change and how. this contact form What did John Templeton mean when he said that the four most dangerous words in investing are: ‘this time it’s different'? I place batch="true" on web.config and the bug appears right away. The project is a web application, not a web site.

Type B originates from 'Albums, Version=, Culture=neutral, PublicKeyToken=null' in the context 'LoadFrom' at location 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\magickecb\4414db97\126f5aaf\assembly\dl3\017fab88\a91238d1_7977cb01\Albums.dll'.

But then, I don't have much experience with using the BinaryFormatter, so I certainly couldn't be sure. –Craig Shearer Jul 17 '09 at 7:46 Then there must be someone

Does sputtering butter mean that water is present? When a page using BadControl executes, DupedControl TypeA gets instantiated via the markup, but BadControl tries to cram it into a TypeB variable, resulting in the error you described. I just cleared all ASP.Net temporary files and re-cycle the IISExpress pool and the error went away. –TTCG Feb 19 '14 at 10:50 @ulty4life I know this is an Many thanks for a second time -Jacelyn Reply Matthew Smith 24/04/2014 at 13:43 Here's another example of how to run into this issue without even referencing the type directly: http://stackoverflow.com/questions/23255892/how-to-reproduce-invalidcastexception-when-binding-to-an-assembly-in-the-loadfro/23255893#23255893

Is "she don't" sometimes considered correct form? It is this sutle difference thatmakes the type casting invalid. Is it possible to bleed brakes without using floor jack? Check This Out The exception message is informative: [A]dummyNamespace.dummyClass cannot be cast to [B]dummyNamespace.dummyClass.

Assemblies, load context http://blogs.msdn.com/junfeng/archive/2004/03/05/84290.aspx Please mark the right answer at right time.Thanks,Sam Edited by SamAgain Monday, March 22, 2010 6:21 PM refine Marked as answer by The key elements in the scenario causing the error are source code files in the web path, and low available memory on the dev machine that is running the application. Not the answer you're looking for? I have try with optimizeCompilations true and false and the same issue.

In her interview, Suzanne defines the Load method as the recommended good practice for loading assemblies. Does every interesting photograph have a story to tell? So the source code files are actually in the web path. So when I try to load it alone is throw this exception.

Likely choices: XmlSerializer (xml; serializes public fields and properties; "tree" only) DataContractSerializer (xml; serializes marked fields and properties (public or private); "tree" or "graph") protobuf-net (binary; serializes marked fields and properties LoadFrom http://blogs.msdn.com/suzcook/archive/2003/09/19/loadfile-vs-loadfrom.aspx 4. Does a key signature go before or after a bar line? If an assembly by that AssemblyName is already loaded, that assembly would be used; or, if an assembly that corresponds to the AssemblyName is found within the probing paths, it will

Type B originates from 'dummyAssembly, Version=, Culture=neutral, PublicKeyToken=fd8dd69e4e14aa6f' in the context 'Default' at location '...\LoadLoadFromLoadFile\LoadLoadFromLoadFile\bin\Debug\dummyAssembly.exe'.

Appears only one one custom control loads, the one that have heavy call. Find the function given its Fourier series What is the definition of "rare language"? How ever I am not sure if the issue have to do with the code - maybe have to do with the grow of the project, or even with an update The nth numerator Why are password boxes always blanked out when other sensitive data isn't?

The issue really came from type creation. It is this sutle difference thatmakes the type casting invalid. Maybe specify a version of the compiled files (i'm guessing DLLs) I hope this helps you fix the problem. Resolved by using a list of the byte (enum data type) and casting during runtime.
