IHostAssemblyStore::ProvideAssembly: CLR throws exception "The located assembly's manifest definiti


PostSharp 2.0 includes a CLR host and implements IHostAssemblyStore::ProvideAssembly.

From managed code, I invoke:
Assembly.Load("logicnp.cryptolicensing, Version=, Culture=neutral, PublicKeyToken=4a3c0a4c668b48b4")
My implementation of IHostAssemblyStore::ProvideAssembly receives the following input for the first parameter pBindInfo:
0x002cd578 {


lpReferencedIdentity=0x03c123f8 "logicnp.cryptolicensing, version=, culture=neutral, publickeytoken=4a3c0a4c668b48b4" 

lpPostPolicyIdentity=0x03c14620 "logicnp.cryptolicensing, version=, culture=neutral, publickeytoken=4a3c0a4c668b48b4, processorarchitecture=x86" ...


My implementation then returns the right stream. Note that the binding identity of that file is "logicnp.cryptolicensing, version=, culture=neutral, publickeytoken=4a3c0a4c668b48b4".

When I return this file from ProvideAssembly, the CLR throws the following exception:

Could not load file or assembly 'logicnp.cryptolicensing, Version=, Culture=neutral, PublicKeyToken=4a3c0a4c668b48b4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Registering controls of current assembly object reference NOT set error


Hi There,

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).

I don't want to register my control using Src, TagPrefix etc. Any ideas?


The type 'DataGrid' was not found. Verify that you are not missing an assembly reference and that

Hi; I'm new to WPF and I was going through the ExpenseIt tutorial on MSDN's website. The tutorial was working fine until I added DataGrid. I got the error message: "The type 'DataGrid' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."     I could not find a clear answer online of which assembly references to fix and how to fix them. Any help would be appreciated. Thanks!     Note: I'm running the following: Windows Vista 32-bit operating system Microsoft Visual Studio 2008 Version 9.0.30729.1 SP Microsoft .NET Framework Version 3.5 SP1

Reference a assembly compiled against .NET 4 CLR from a .NET 2 CLR

Hi, I just read this aricle http://msdn.microsoft.com/en-us/magazine/ee819091.aspx. In Figure 2 (Will These Runtimes Load in the Same Process?) You can read that it is OK to load an assembly compiled against .NET 4 CLR from an application compiled against .NET 2 CLR. But later in the aricle under "Library Developers and Consumers " you can read that it will not work for libraries. I have a web application (ASP.NET) compiled against .NET 2 CLR that needs to reference an assembly compiled against .NET 4 CLR. Will this work or not? I have tried it several times and it works fine. I don't understand the text in the aricle becase Figure 2 says it's OK but the text under "Library Developers" says it will not be OK. But for me it works. Maybe I have just had luck?

VS 2010 Isolated Shell, WPF Designer & Custom Controls produces some assembly reference errors

Hello, i currently try to use the VS 2010 isolated shell for providing a custom WPF editor.As described in the headline the WPF designer is 'partly' not able to find all assemblies (details below). After some research the only similar problem description i found here . Unfortunately I could not find any solution for my problem there. These are the steps i have successfully finished: - create a vs isolated shell application with some basic extensions (some tool windows) - create a Custom Project template based upon the MPFProj project (as describe at: here ) - Add the needed reference for custom control in project template - Create and edit XAML markup (no code behind, only markup) - Compile and run XAML Now, the following problem occurred (as a step by step description): - I add a custom control to the toolbox using the context menu "Choose Items..." (ok ) - I drag this custom control from the toolbox into the WPF designer view (ok ) - The custom control is rendered correctly and no assembly reference errors occurred (ok ) - I hit the F5 button in order to execute the XAML markup -> The application is starting correct and looks as exspected (ok ) - I close the running application (window) -> Now the WPF designer view seems to refresh and 'tells' me that an assembly (the one of the custom control) could not be found (error!!! ): There error text is: "Th

"Assembly '...' Was Not Found" When including a reference to a local namespace

I've got a WPF application with a window and a usercontrol:   Window:   <Window x:Class="UI.Windows.Main" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:UI.Windows.Documents" Title="Window1" Height="600" Width="800"> <DockPanel> <!-- Snip --> </DockPanel> </Window>     UserControl:   <UserControl x:Class="UI.Windows.Documents.MyDisplay" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x=http://schemas.microsoft.com/winfx/2006/xaml> <Grid> <!-- Snip --> </Grid> </UserControl>       Now, when I try to look at this in the designer i get an error saying Assembly 'UI' was not found.  I've searched high and low, but the internet is full of references to this being a 2005 issue and the solution is to upgrade to 2008.  I'm already using 2008 (don't even have 2005 installed on the machine), and I still get the problem.

How to reference specific version of a GAC assembly



I've got an VS 2005 C# application that references 3 assemblies in the GAC. These 3 assemblies are part of a framework we built and are versioned We're now rebuilding the VS 2005 application. Part of that involved some upgrades to the framework who's assemblies are in the GAC. I rebuilt the framework assemblies with the changes using version and put those in the GAC on my development machine. So now I have both version and version in the GAC. When I try to run the VS 2005 project from the debugger, I get a runtime error complaining that one of my classes is violating a generic constraint of one of the framework's generic collection types. My type is correct so this was a version issue. I changed my references to my framework assemblies to Specific Version = true and verified they're referencing but it still gets the error. If I remove the assemblies from the GAC, it works again.

Can I have both in the GAC and reference the specific versions?

Problem with assembly reference not updating


I have a solution A which references an assembly in solution B. I added the reference to the project in A by right clicking on the project > add reference, and finding the dll in the bin/Debug folder of the project in solution B in the Browse tab.
However, the reference to assembly B is not being updated in solution when I update the code in project B, even though I am making sure that I recompile the code in project B and then in project A. This means I am unable to debug A properly because the source code does not match the executable (I've checked and the location of the file the breakpoint is added to is correct).
I can go into the bin/Debug folder in project B, the date modified fields for the dll and .pdb files in

report definition cannot find custom assembly in VS 2010



I;m trying to use custom code (C#) in a report definition and I have followed the steps outlined in MSDN to get this done. However, whenever I compile the code, I keep getting the following error

"Error while loading code module: ‘GSLibrary, Version=, Culture=neutral, PublicKeyToken=null’. Details: Could not load file or assembly 'GSLibrary, Version=, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."

I've scoured through this forum and the net looking for answers but nothing seems to work. The closest answer was to mark the assembly as a trusted code module in the current app domain, but VS2010 complains that this method is deprecated.

The assembly works just fine elsewhere in code. How do I get custom C# code to work with the reports I am creating.

Thanks for your help.
