"Unable To Emit Assembly: Referenced Assembly?
Jun 1, 2011
I'm wanting to include a system tray icon in my WPF project, and found this resource:[URL]..which looks like it will work beautifully, but it's written for C# and I'm using VB.net for this project. I downloaded his project and built the notifyicon as a DLL, then added as a reference to my project.
It throws up an error: Unable to emit assembly: Referenced assembly 'Hardcodet.Wpf.TaskbarNotification' does not have a strong name So I'm trying to figure out the best way to proceed. Do I need to strong name it, or is there a better way to do this?

I have recently upgraded an VB6 project to vs2008. I was almost finished when the following error occured. Unable to emit assembly: Referenced assembly AxInterop.MSFlexGridLib does not have a strong name Prior to this error appering, I tested my app several times and it was fine. Only after publishing it did the error appear. I have tried all solutions I could find, but nothing helps. I have read [URL]

I have created a visual basic class library named dataLibrary and have added it as a reference in a visual studio tools for application program in infopath 2007, and imported it.
Now when I try using a class defined in the library, I get the following error:"Unable to emit assembly: Referenced assembly 'dataLibrary' does not have a strong name"

I would like to enumerate an assembly's referenced assemblies and determine what should or should not possibly be included as a dependency in deploy scenarios.For obvious reasons I would want to exclude those assemblies that would be included by the CLR install.Is there any way to track back an assembly to being part of the default install of the CLR?

I got warnings on my project, does somebody know how to reference this assembly. this is probably because the project has these crm.mytextbox type textboxes and other controls instead of normal system.windows.forms.textbox.Warning1Could not find type 'crm.Mycombox'. Please make sure that the assembly that contains this type is referenced.If this type is a part of your development project, make sure that the project has been successfully built.00

I am loading an assembly using LoadFrom method on a file located in another folder. The assembly is called VisualCronAPI.dll. The assembly that I load has references to another assembly (VisualCron.dll) which contains some general type definitions used in VisualCronAPI. The file VisualCron.dll resides in the same folder as isualCronAPI.dll.When using LoadFrom I see in the output that VisualCron.dll is loaded. I am able to retrieve all methods in VisualCronAPI that uses parameters from VisualCron.dll. I am able to see parameter values However, when trying to create a Type using the following code I get an exception:
Dim t As Type = assem.GetType("VisualCron.NetworkCredentialClass, true)
Exception: Could not load type 'VisualCron.NetworkCredentialClass' from assembly 'VisualCronAPI, Version=1.0.3.32487, Culture=neutral, PublicKeyToken=55f7a52402de1c04'.

Is it possible to load a referenced assembly only if the .NET Framework version is lesser than a specific number? I'm using a selfmade LINQ library on .NET 2.0, but if the framework is 3.5+, it should use the M$ LINQ library, and ignore the selfmade one.
Here's my library: [URL]

When running setup to install published program, the following message occurs: System Update Required: Unable to install or run the applicaiton. The application requires that asssembly CrystalDecisions.CrystalReports.Engine Version 10.2.3600.0 be install in the Global Assembly Cache (GAC) first. This version is listed in the references of the program and in my mind, be included in build. How do I get by this error?

I am loading an Assembly using Assembly.LoadFrom() as the assemblies are located in a different path from Application Base directory.
Dim oAssembly As Assembly = _
Assembly.LoadFrom("C:\MyFolder\" + ddlXlate.SelectedItem.ToString() + ".dll")
And I consume a Type from that assembly without any problem:
oXML = CType(oAssembly.CreateInstance(sBaseType + ".XlateContainer"), _
XlateBase.XlateContainer)
However, the problem occurs when I try to use a Type from this assembly from within another method like the one below:
oComboBox.DataSource = _
[Enum].GetValues(Type.GetType(sType + "+ItemEnum," + sAssemblyName))
sAssemblyName is the one I loaded using LoadFrom() actually. After it said it cannot find the assembly, I used AssemblyResolve event which solved my problem :Subscribing AssemblyResolve event :
AddHandler AppDomain.CurrentDomain.AssemblyResolve, _
AddressOf MyResolveEventHandler
Event Handler Method:
Private Shared Function MyResolveEventHandler(ByVal sender As Object, _
ByVal args As ResolveEventArgs) As Assembly
Return Assembly.LoadFrom("C:\PSIOBJ\" + args.Name + ".dll")
End Function
And I thought maybe the error occurs because it cannot find a dependent assembly defined in assembly manifest file I loaded using LoadFrom() already but when I checked the args.Name, I saw it was trying to load same assembly and after that it worked without any problem. So basically a type in the loaded assembly cannot be found before the event adding change.
My old code was using AppDomain.CurrentDomain.Load() and Assembly.Load() methods and they were working fine without the AssemblyResolve event. I was able to reach types in dynamically loaded Assembly from every where within the same AppDomain.
LoadFrom() can find dependencies automatically within the same requested assembly path and that couldn't be problem as everything this dll needs was there. So at first it looked like a AppDomain problem to me as it looks like it seems it can reach assemblies from Load context instead of LoadFrom context and I am now using LoadFrom context.But now it seems I should pass oAssembly instance evertwhere to use any type from the loaded assembly?Doesn't it load the assembly where I can reach it everywhere (same AppDomain) using simple Type.GetType(...) method?

I've got an exception when I deployed my application: "the located assembly's manifest does not match the assembly reference" What I remember is changing the project name from the previous source code, does it affect that much?

I have created several DLL (.NET) libraries that are used in several projects. In these DLL libraries I want to know/retrieve which assembly (EXE) calls/uses the library, so if possible I want to know info like assembly name (EXE), strong name, version number, etc.
NB: Examples may be in C# or VB. I use both languages.

I have written a .net assembly which plugs into to a third party COM application. The .net assembly is COM visible to the third party application. However this .net assembly references other regular assemblies. If I put these assemblies in the GAC the COM visibile assembly sees them without a problem. However for various reasons I do not want to put them into the GAC but I cannot get my COM visible assembly to see the other assemblies when they are in other locations. I have tried putting them in the same directory as the COM visible assembly. I have tried putting them in the same directory as the third party app's exe but neither of these work.

I created an application using VS2008. I am having a problem on only one PC. If I log on to the PC as the domain administrator, it deploys and runs just fine. If I log on as the user I get an error that basically says "The referenced assembly is not installed on your system. (Exception from HRESULT: 0x800736B3)". The error comes when running Venodr.appref-msl. VENDOR is the name of the application. The source is System.DeploymentSystem.Runtime.InteropServices.COMException I upgraded the user to a domain administrator and it still will not run. The PC is XP SP3

I have a stand-alone WinForms application, let's call it "Program A." Program A let's a user create a file and save some information to it. Program A also exposes some public classes.Another stand-alone WinForms application ("Program B") references Program A, and uses some of its public classes.
However, some of Program A's classes need to open the file the user created in order to retrieve data from it. In Program A, the location of the user's file is saved in the "Settings" (as user-scope settings of course) and are retrieved (this is a VB.NET app) via My.Settings.
This is all well and good until Program B runs - when it runs and uses the classes from Program A that need to read from Program A's My.Settings, the settings are blank - it's as if they were reset (as when you run Program A for the first time or under a new user account). Any application-scope settings are kept, but any user-scope settings are reset to their default values (whatever they were set to in the IDE when Program A was written).
[Code]...
Assume that the user has already run Program A at least once and opened a file, so Program A's My.Settings.UserFileName should be set.
When Program B calls Foo.GetStuff(), it doesn't return anything because My.Settings.UserFileName doesn't contain the user's file name - more accurately, it contains whatever the "default" value for that setting was (as set in the IDE when you set up the setting in the first place). But, if you turn around and launch Program A, it remembers the user's setting for UserFileName.
So - the question is: When calling a function in a referenced assembly, why are the user's settings not retained? Is there an explanation for the behavior I'm seeing, or am I missing something terribly obvious? Or perhaps I'm just going about this all wrong, and I shouldn't have made any of the public classes in Program A rely on anything in My.Settings in the first place?

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.
Alternatively, if that's not possible, how about checking the modules in an assembly?

I am building a dll-Assemby A which references another Assembly B. Assembly B is strongly named and installed in the GAC of my development computer. An other computer will not have assembly B installed in the GAC.
Question: If i handle strongly named assembly B like a private assembly and copying it into the bin-directory by specifying local copy = true in the properties-window, will the programm run on the other computer?

I have a web site that uses the both c# and vb.net in the app_code section. The different languages are separated into their own folder and correctly configured in the web.config.
<codeSubDirectories>
<add directoryName="BasicCode"/>
<add directoryName="CSharpCode"/>
</codeSubDirectories>
This works fine 95% of the time. In production using 2 load balanced servers I sporadically receive an error message along the lines of:
"Unable to find assembly
'App_SubCode_BasicCode.xxx,
Version=0.0.0.0, Culture=netural,
PublicKeyToken=null'.
The site is hosted in IIS7 and I think it has something to do with the name of the dll assigned during dynamic compilation. I do not see this problem in a single server environment. Could this be because when the session is balanced to the second server the dynamic compiled dll name is different?

In our application user needs to login to a particular company. We have an option in menu that would let user to select another company while application is open. When user selected other company the application restart itself along with the settings for new company.
Until first load everything was fine and user can select other company from the menu, but when application restarts itself it throw and exception stating Unable to load assembly. Whereas if we again try to run the statement in debug mode everything goes fine. Basically, on alternative loads we are getting this error.[code]...

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.

I am trying to upgrade a project from VS2005. It is a VB.NET project B that depends on a C# project that references a C++ dll, A.dll. I am getting an error saying 'Unable to find assembly A_class, Version 2.0.0.0, Culture=neutral, PublicKeyToken=null'. The targeted platform of the C++ project is 4.0 and since that project depends on others, I can't downgrade it. But I did set the platform for the VB.NET project to 4.0. What else does the Version 2.0.0.0 refer to ? I have tried to create a brand-new project and added the vb forms into it after I have built it successfully. The C++ dll is in the output directory, if the VB project doesn't find it there, it doesn't get to this point. During build. I either get no error (but forms don't load) or I get 2 errors (one for each form):

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.
