I have an application installed on my local disk.This application runs with FullTrust privileges.I'm trying to load an assembly giving it FullTrust (same privileges of the loader).My assembly is located on a network share.I'm actually using this code but I get a security exception:
An exception of type 'System.IO.FileLoadException' occurred in mscorlib.dll and wasn't handled in the appdomain it was thrown fromAdditional information: Could not load file or assembly 'Main, Version=2.2.2029.19859, Culture=neutral, PublicKeyToken=2244f6f9e95cedae' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT:
Out of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.
Assume a .NET class library code that, for example, writes to the Windows registry. Then this code has problem to run over internet, because default Internet policy does not give access to write to the registry.By adding a RequestMinimum statement in the assembly we can specify that the code requires permission to write to write to the registry. This will not alter the fact that the code does not have the permission, but will stop the assembly from loading; the runtime will throw a System.Security.Policy.PolicyException and identify the permission that is required.Do you now any other examples of using evidence, security policy and permissions (the key elements of code-access security) to prevent an assembly from loading on a web server?
When ever I finish simple programs no matter what it is and i click to debug it it comes up"Error while trying to run project:could not load file or assembly"project name" or one of its dependencies.the module was expected to contain an assembly manifest"
One of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.
On the earlier version of VB.net 2003, I could run a wizard to give full trust to a .Net application on the network. With VB.net 2008, there is no longer a wizard to do this. I did some Googling and most of the references I find refer to using Caspol for .Net 2.0. That doesn't seem to be an option .net 3.5 (I can't find Caspol in the framework folder). Does anyone know how to do this for VB.net 2008?
I have a file name, like "Foo.dll," for a library that I know is in the bin directory. I want to create an Assembly object for it. I'm trying to instantiate this object from a class that's not a page, so I don't have the Request object to get the path. How do I get the path I need to use Assembly.Load()?
Could not load file or assembly 'file:///C:Windowssystem32Rule.dll'. The system cannot find the file specified.
The problem is that the same exe works in my development environment but not on productive server. The program is a tool that should run as a Scheduled Task on Windows Server 2008. It consists of an exe, one so called Database.dll and the Rule.dll. The exe should load the Rule.dll dynamically in codebehind but it fails with the above error only when started from Task Scheduler. Why is it looking in System32 folder and not in the Application folder? Is it an UAC-issue?

I'm working with a 3rd party assembly to implement something in our in-house software. I can make the refence and work with the library without a problem, but when I run the program to test it i'm getting this error "Can't load file or assembly "assembly file" nor either of its dependencies. The system couldn't find the specified file" (i'm from Mexico, exception is in Spanish so i had to tanslate it, sorry for the poor translation) I have given read and write permission to the file, the folder, and for all users and still wont load it. I saw that the assembly has the PublicKeyToken=null, does that have any to do with that i cant load the assembly?
I am getting the following error message below and don't know why. I've even rebooted my machine and it still won't work.

if I want to open my vs2008 project, I get the error "Could not load file or assembly 'Microsoft Build Engine, Version=3.5.0.0, Culture=neutral, .... or one of its dependencies. The system can't find the specified file." Yesterday it has no problem and today I get this message. I have uninstalled nothing, I have net framework 3.5 and in the meantime 4.0 too, I use win 7 x64. I tried to repair the install of vs2008 with the dvd, no succes. what I should do to get this to work again? I don't want to reinstall win 7 (inkl. format the system drive).
EDIT: I checked the system with the net verify tool, and it comes out, that some dll-s in the assembly directory are missing. Now, I clean up all net framework on the system, then I will install the net framework 3.5 sp1 and let's see, whether it works or not.
EDIT 2: I even can't install the net framework 3.5 sp1. I downloaded the full pack from microsoft and if I click on it, nothing happens. Why?
EDIT 3: after reinstalling all vs2008 components and after running the net removal tool again, I wanted to install vs2008 back. And the install says: the net framework 3.5 (x64) is installed. I know, win 7 contains it. Then how the hell can I uninstall and reinstall the net framework 3.5??
Usually, when I create an application, all I need to do is copy the .exe file from the "inDebug" folder to run onto other machines.
But this time, I've got a 3rd party control. So, copying the .exe isn't good enough. I get a message as soon as the application loads "Could not load file or assembly ..."
I have added a "Setup and Deployment" to the project, but that still doesn't seem to include all of the files to the 3rd party control.
Because after successfully installing this application, the same error message is displayed "Could not load file or assembly ..."
how I can get this application to run on another machine without installing this 3rd party control first?
I created a setup file for my project, and i keep getting a can not load file or assembly error.There are no erros in my build or project.I can test this, and it works fine on my localbox wile in my vs.net project.When i create a setup file, and test it on another machine, i get this error below.
After working all morning and finally getting my dll to talk to my rdlc files, I decided to import my functions into my other code, but I get the aforementioned error.My dll is in my PrivateAssemblies folder as well as both my debug and release folders (x86 in case you were wondering).
I created two projects. They are VB.Net dll and c# .net dll file. I am using VB.net dll file into c#.dll file. when i test c#.net dll file it is giving error message Could not load assemble. if i use both then it is working fine.But i have to use only one dll file. Let me know how can i do with only c#.net dll file.
I would like to load a class library at runtime. As such, I thought I could use reflection to do so.However I am receiving the exception "Unable to cast object of type 'MyLibrary.LogSystem' to type 'MainApp.ILog'." in my main application. To start with I created a Class Library (VS2010) with a simple interface and one class that implements the interface.
I am working on a project where I have to load assemblies (lets call them tasks) at runtime, run the task and then be able to kill off the whole assembly so that the dll can be replaced without interrupting the main application.There are many of these tasks running within the main application,some run sequentially and some run in parallel.Occasionally one or to of these tasks need to be updated and then re-added to the queue. Currently we are stopping the entire application and interrupting the other tasks at whatever stage they are at, which is not ideal.I have figured out that I will have to load each assembly into a separate AppDomain, but loading the assemblies in those domains is proving difficult, especially when I need to actually run the tasks and receive events from them.I have been looking into this problem for a couple of days and have still not managed to get a working proof-of-concept.
I have an Interface for the tasks which includes a 'run' and 'kill' method (subs) and a 'taskstep','complete' and 'killed' event.'taskstep' returns an object to be cached later, 'complete' fires when the whole task is done and 'killed' fires when it is ready to be unloaded.There should also be a timeout on the whole process of two hours and a timeout of 2 minutes on the killed event in case it gets stuck, at which point I would like to be able to unload it, forcing any threads to terminate (which is what 'kill' should do anyway).Each assembly may contain several tasks, all of which should loadable be unloadable.I have no problems loading these tasks as 'plugins' but am lost when trying to both use them and unload them. If I have to create some elaborate wrapper then so be it but is what I need even possible? I have tried inheriting from MarshalByRefObject but I do not even know the assembly fullname unless I load it first, which then locks the file. I have tried loading from a byte array of the assembly. This means that the file is not locked but a copy of it remains in the current appdomain. This will become problematic over the following months / years![code]
I have a web application in .Net in which I use Ajax controls in some pages. Those pages are working in localhost, but when hosted, the pages in which Ajax included shows following error.

let's say I have 5 DLL files that are each a partial class, that they should form together... Is there a way I could load these 5 files into 1 assembly object ?
I have developed one class library using .net 3.5 framework and i am using this in another project developed in .Net 2.0 framework, in this case i m getting the following error. Could not load file or assembly 'AssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
I am facing this problem when running my application on 64 bit os .While it is working good on 32 bit OS which is my development environment also. I do not know how to get rid of it. Target CPU is set as Any CPU (there are no other option coming there).
I recently added hsProgressbar.dll to my Program, it worked fine, but then I decided to remove it from my Computer and also remove it from the references...however..the Warning is still there? How can I completely remove it, so that I don't get the error anymore?
I have two projects in a solution. One is a class library with my FTP, GPG and some other classes that get compiled into a dll call CBI.Utilities. The other is my main app which in a few places call the ftp class. I added the reference to the main solution by browing to the project from references under the main solution and now I get this error when I try to instantiate the ftp class.
"Could not load file or assembly 'CBI.Utilities, Version=1.0.2053.21021, Culture=neutral, PublicKeyToken=78bbe40a91a1660e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)" Should I be making a reference to the DLL or to the projects. Either way I end up with a reference cbi.utilities.
Im trying to load the DataBindingLab from MSDN [URL]and im getting the error "Unable to load the metadata for assembly DataBindingLab". Does anyone know how i would be able to resolve this. The next part of the error is "The system cannot find the file specified" but no information as to which file is missing is provided...
I am referencing a DLL in my project which works OK on both inside and outside of the IDE on my development machine but when I deploy to another machine, I get an error "Could not load file or assembly...".
I've had a vb.net application for quite a while. Today, when I tried to load a form (one of many in the app) in Design mode, I got the error: "Could not load file or assembly 'Interop.MSMAPI, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." This form is the only form using msmapi, and the only one that won't load in Design mode.I can edit the form's code, run the application, and deploy the application. But I cannot access this form in Design mode. It's been a few months months since I've opened this form in Design mode, but it worked last time I tried it.
I am creating DLL file using c# .For that i need one DLL file. That is created in VB.so i just i add that dll file into my project via add reference option.But when run the projects am getting this error.
Could not load file or assembly 'BOL3, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
