I have a very serious issue with my ASP.Net server when referencing (indirectly, it's a dependence of a referenced assembly) some third-party assembly.When I connect to the server I obtain this exception :
[Code]....
When I remove the assembly from the "bin" directory the site is accessible and works normally.So what might be the issue and how to get rid of this exception ?I'm using Visual Studio 2010 Professional.
the situation is quite complex ( and my english very basic) but let's try to explain:
i'm developing a Asp.net web service calling a method from an external dll. This external dll calls some method from other .net dlls. So we have:
Asp.net WS ----> External.dll ----> other.NEt.Dll(---> other .netdll)
You have to know that the external dll uses a path ( given by an initialize method) to resolve its internal reference. In conclusion i have a web application with an added reference to my External.dll and a fully trusted path ( c:EXTERNAL ) full of all the .net dlls needed by external.dll. Looking around i've found this code to add to the application_START:
Dim path As String = String.Concat(System.Environment.GetEnvironmentVariable("PATH"), ";", "c:EXTERNAL)
System.Environment.SetEnvironmentVariable("PATH", path, EnvironmentVariableTarget.Machine)
this add my c:EXTERNAL to global environment PATH. With this configuration running from the Visual Studio development server i get no error and it all works correctly. When i publish the application on my local IIS server it gives various errors: At first the result is something like:
Failure reading <Myobject> control of <(static)> type
Unable to create <myobject> object (<C:(WRONGPATH)
eeded.net.dll> assembly)
To resolve this i've tried to add the needed .net dlls to the /bin of my application in wwwroot but the result is something like:
Failure reading <MyType> control of <Myobject> type
Error returned by .NET Framework:
System.ArgumentException: Un oggetto di tipo 'ComNet.BaseControl.LoginDisplayLayout' non può essere convertito nel tipo 'ComNet.BaseControl.LoginDisplayLayout'.

this time it looks like it's loading the same dll but from different location causing conflicts. Now that's all. Its hard for me to explain this dll-hell but basically i would like to replicate whats happening when the application works well in the visual studio development server. I've also read that IIS does not resolve Added PATH without rebooting so i tried to add c:external manually to the PATH and reboot but same errors appears.
I encounter a problem...error is Ajaxcontroltoolkit.dll is in bin folder, but still I get this follwoing error.Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The module was expected to contain an assembly manifest.My code is (in .aspx file):
[code]...
Can you tell me how it is better to load classes from the same assembly for multiple times? I will explain:
I have a usercontrol that loads the class from assembly A.DLL using (MyAbstractClass)Assembly.Load(path).CreateInstance(type) each time requested page loads. The control can appear on the page many times (about 20-30) and each of them can load the different type from A.DLL...so if control exists on page 20 times, 20 times (MyAbstractClass)Assembly.Load(path).CreateInstance(type)
has been executed.
The question is performance...
Does ASP.NET caches DLLs already loaded dynamically? After first (MyAbstractClass)Assembly.Load(path).CreateInstance(type)and first IO, will ASP.NET load A.DLL from cache on other executions ? Or I need to implement some kind of assemblies caching myself?
If I need to implement caching myself, what is the best and fastest way to do it?
I have an application written in VB.NET that sends XML to another server and it takes another XML. I am using HttpWebRequest in sending it but when I get the request stream I got this error. Please note that the application is working on my machine, but on the deployment on server I got this error.

I have recently discovered that I am affected by this bug http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71515.html
Well,at http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71529.html they say the work around is to create a global policy assembly and redirect the assemblies that way since it is not read from the web.config.
How do you actually do what they describe there? There is a huge documentation gap in that area with Mono.Also,I can't just recompile the assembly to use the new Mono assembly versions because the assembly is closed source.(but it does work with Mono.)
I downloaded the trial version of abcpdf, which is absolutely fantastic!
Anyway, real simple, you just need to reference the .dll and off you go...
So, I got my code working, but when I moved to production server I hit a wall.
It definitely has to do with the .dll because when I comment out the pdf sub routine, the code executes and completes all other tasks. When I uncomment, It's not working.
The trouble is, on my server I don't have the full version of VS, so I am unable to add a reference, which I presume takes care of the web.config settings? I manually dropped the .dll into the bin folder and I added the assembly line into web.config, but, as I don't have the above, I am not sure if the token key is correct.
To test this, I uploaded the working .dll file to my server, which I assumed the key is associated with, but still the same.
how to either get the correct key and/or how to reference an assembly manually? Is there something I have missed?
I have strange problem with missing assembly of my application after IIS restart. My application is installed correctly to IIS 7.5 (windows 7) and works fineAfterwards I make a restart of IIS serverNow my application is not working properly, some classes (assemblies) are missing. I've insterted a code to my application that writes all avaible assemblies into my log file (see code below ) and really a few assemblies are missing[Code]....
Restart of IIS or even restart of windows is not enoughThe workaround is to make some change in web.config or to rewrite some *.dll by the same dll library (in order to force IIS to reload whole application)afterwards it works fine again (till next restart of IIS) for better understanding I've recorded a video for you [URL] Do you have any idea how to solve it? or what what to check? (My application is based on ASP.NET and I'm using ported version of Jade framework (framework originally created in Java).) This problem is related to another problem on this forum [URL]
I built an assembly, and that assembly refereces a DLL in my bin folder (lets call it Bob.dll). so multiple users may have different versions of Bob.dll...but by and large they all function the same.
However when my assembly gets dumped into the bin folder, it wants the version it was compiled against.
Is there a way to compile a reference such that it'll just be happy with ANY version?
I know it can be done with assembly binding in the webconfig, but I dont want users to have to do that.
When I drag/drop a Chart or ReportViewer control onto my page the web.config updates with said assemblies however my website fails to load. Removing the controls and assembly tags successfully starts the website however I cannot seem to understand why the website has issues when the Chart, for instance, is loaded.
The site is live within an intranet space which was originally created in .asp however the .aspx pages I create do work with other controls such as gridviews etc.It seems altering the web.config causes issues but I just want to know how I can get the chart etc controls working?
I have writen a simple asp.net App to display stats in the call center I work in. I was working fine until yesterday afternoon when i started getting the following error
Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified. The server is only running windows 2000 teminal so can only run .net 2.0. I am using Visual Studio 2008 Express to write the code and have set the Target Framework to .NET Framework 2.0 under the Properties page and hit the F5 key and it ran fine.
The company whose program we are using developed an API that can be accessed from a web application as well. They provided us with a sample of an ASP.NET application which works fine. When I open the *. Sln file, and then the Default.aspx page (http://localhost:65250/Default.aspx) I don't have a problem using this DLL.
But, when I copy the codes on the server and I try to access the application via web directly, like http://servername/default.aspx, it is telling me that the assembly from this DLL is not registered.
I noticed that when I open this application through *. Sln file, I don't see the BIN folder, but a REFERENCE folder instead.
My question is: how can I register this DLL so I can use it via web directly?
I am using Visual Studio 2008 and my project is a Web Application Project so that I can compile my all files in just one assembly.
It is working but web form code behind files are compileing into single assembly but aspx files are not compiling. In addtion, these aspx files are present in the directories and they can be viewed.
Is there any technique to compile my all files into single assembly?
I have a dll which is in the bin folder (version 1.0.6125.0 ) and in GAC version of the dll is 3.5.0.0. Both the assemblies are strongly named microsoft dll's .
Now I want the dotnet CLR to search in the GAC instead of in local bin folder.. I know the solution to the problem would be to delete the dll from the bin directory and automatically application will search for dll in GAC, but in my case, I cannot delete the .dll file in bin directory, since we do not have control over the PRODUCTION servers.
I get the following error
The type 'System.Web.UI.ScriptManager' is ambiguous: it could come from assembly C:inetpubwwwrootAppNAMEinMyDll.DLL or from assembly 'C:WINNTassemblyGAC_MSILMyDLL3.5.0.0__31bf3856ad364e35MyDll.DLL'. Please specify the assembly explicitly in the type name.
I had accidently moved a dll which sits in the BIN directory from my local machine to Production server. Later I realised that the same dll exists in the production server in it's GAC. Now I do not have ermissions to delete that dll from the bin directory on the production server. I am planning to use assemblybinding codebase and redirect attributes to make the application to search for the dll in the BIN directory instead of the in the GAC
I get the following error
The type 'myassembly' exists in both 'c:WINNTMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Filesdw82f12d83c45d61ceassemblydl3e45c2bc4�06e4169_8855cb01myassembly.DLL' and 'c:WINNTassemblyGAC_MSILmyassembly3.1.21.0__7780ffc6c71e90a4myassembly.dll
how I have use this assemblybinding attribute in Web.Config to point to the dll in the bin directory.
I'm having some difficulties registering a custom control from a class library in my webapplication's web.config file (or directly on a single page at all). These are the steps I've taken thus far:
1. I have a class library that generates a dll called "Core" and my webapplication has a reference to this "Core" assembly.
2. The Core class library contains a class called AjaxTable which is of namespace "Core.Presentation.DataViews".
3. AjaxTable extends System.Web.UI.Control.
4. I have added the following to my webapplication's web.config file.
<add assembly="Core" namespace="Core.Presentation.DataViews" tagPrefix="core" />
5. Since the previous didn't appear to work I tried the following variant:
<add assembly="Core" namespace="Core.Presentation.DataViews.AjaxTable" tagPrefix="core" />
It seems like I must be doing something small wrong or missing a step. Can anybody give me any advice? Thank you all in advance.
how to register same name assembly but different version in webapplication
View 1 RepliesI have 2 assemblies with the same name but with different version 1.0.0.0 and 1.0.0.1. I have installed it in GAC and want to use 1 of these versions during run time from my C# application(for e.g - based on locale) in asp.net 2.0.
View 5 RepliesI have an asp.net website application that uses MySQL as the database. It has been working just fine until... I updated from MySQL version 6.1.3 to version 6.3.4. Prior to updating, I uninstalled 6.3.1. I changed my web.config file to reference the new version as well as the machine.config. It works fine on my development machine. I publish the website to the production server and when I browse to this site I get an error:
[Code]....
I have searched the entire server for any text corresponding to "6.3.1.0" but nothing found. It appears like there is something in some configuration reference that has not been updated to the new version of MySQL.
I have a hundred or so .Net 1.1 legacy assemblies that reference the unsigned Assembly_A. I have no source code for any of these assemblies.
We have developed Assembly_B, which contains upgraded, backwards-compatible types originally found in Assembly_A. I want those hundred legacy assemblies to now reference Assembly_B.
I would really rather not use Reflector to decompile all these. Is it possible to use ILDASM to produce the IL for each of these legacy assemblies, update the references, use ILASM to create the new DLL, and pop the new version into the /bin directory?
I've got two sites that use the assembly, all of a sudden neither one works and I get this error, although on my localhost it al still works fine. Is this an error on my side or could it be on the server.Server Error in '/' Application.Parser Error Description:An error occurred during the parsing of a resource required to service this request.
