.NET 3.5 built Mixed mode assembly unable to load in .NET 4 (even after using app config) without .N

Posted By:      Posted Date: October 01, 2010    Points: 0   Category :.NET Framework
 

I am trying to run a .NET 3.5 built mixed mode assembly in .NET 4. I was able to do that by adding an app config file with the following content:

<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>
</startup>
</configuration>
The problem is that I used an XP machine and installed .NET 4 on it (without any other previous versions of .NET). When I tried to run the same thing, it gives me an error saying it is unable to load the assembly in .NET 4.

Any idea why this is still depending on .NET 3.5?

"Mixed mode assembly is built against version 'v2.0.50727'.... " issue and use custom config file

  
Hi, My Winform applilcation has used Microsoft.SqlServer.Management.Common namespace(assembly :Microsoft.Sqlserver.smo.dll/Microsoft.Sqlserver.ConnectionInfo.dll) and developed in .NET 4.0. Problem:Application is throw an exception when it tries to use above assembly reference methods. Full error text is shown below, "Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. " Error is resolved when we include "app.config" file with below code, <?xml version="1.0"?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration> But, I need to keep configuration file as "renamed.config" and not to include app.config file as of the project requirement.I have set configuration file as "renamed.config" file using below code, //AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", "d:\\reanmed.config" ); I have also included <Startup> element in this "renamed.config" configuration file and removed the app.config file.But it raise me below error, it always expect app.config file with <Startup> element to resolve this iss

First, yes I've read every article I can find including this one: http://msmvps.com/blogs/rfennell/archive/2010/03/27/mixed-mode-assembly-is-built-against-version-v2-0-50727-error-using-net-4-development-web-server.aspx Of course it's for web server stuff, but I found this in my config file and added it. However, my problem now is that if I build in release mode I get a hard error in the error list telling me the same thing, even though it runs fine in debug and has the information in my app.config file. The really anoying part is that the error doesn't tell you WHICH assembly is the offending one. Anyone have any ideas?

System.IO.FileLoadException Mixed mode assembly || System.BadImageFormatException: Could not load fi

  

Im trying o build my WCF project and im developing on Visual Studio with x64

 

Ive trid every configuration and when i use the x64 dll's I get the following error:

Mxed mode dll unable to load in .net 4.0

  
I am currently facing an issue where a mixed mode dll is unable to load in .net 4.0 when invoked dynamically. I am getting the following exception: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.I got to know that adding a config file with the follwoign info in the app would help:<configuration>  <startup useLegacyV2RuntimeActivationPolicy="true">    <supportedRuntime version="v4.0"/>  </startup></configuration>Now, the issue is, this dll can be used by many apps in Dev10. I need some mechanism to add config file with the dll, so that it works whenever the dll get loaded.Is there a way to have dll.config file?

Could not load file or assembly - Web Deployment Project

  

Hi,

I have the following projects in a solution :

- A Web Application

- A Class Library

- A Web Deployment project

The Web Application compiles and run fine when I don't go through the Web Deployment Project. However when I try to use that, I get the following error:

Error 1 An error occurred creating the configuration section handler for hibernate-configuration: Could not load file or assembly 'NHibernate' or one of its dependencies. The system cannot find the file specified. (F:\Folke\Folke.csproj_deploy\Release\web.config line 4) 1 1 Folke.csproj_deploy

This is the beginning of my Web.config:

SSRS 2005 "Mixed" Authentication Mode

  

I have a web application where users can authenticate using either SiteMinder or Windows domain accounts.  This is actually configured as two separate virtual directories within IIS 6.  Both applications need to use the same instance of SSRS.  Is it possible to configure the SSRS web application so that if a user is authenticated by SiteMinder it impersonates a Windows account, but if they are already Windows-authenticated that account is used instead?

Mixed Mode application suddenly stops loading assemblies

  
I have a mixed modes application that will occasionally stop executing managed code assemblies after a Windows update. This has been occurring for over a month now so I have not been able to identify any particular update as the problem. We see the problem predominately on XPSP3 but have also seen several times on Vista and once or twice on 7. On a machine that stops working the Fusion log will show a file not found error on the last assembly loaded. LOG: This bind starts in default load context. LOG: No application configuration file found. LOG: Using machine configuration file from c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\config\machine.config. LOG: Post-policy reference: AProvider.Data.SqlClient.resources, Version=3.0.0.0, Culture=en, PublicKeyToken=c84cd5c63851e072 LOG: The same bind was seen before, and was failed with hr = 0x80070002. ERR: Unrecoverable error occurred during pre-download check (hr = 0x80070002). If I delete this assembly, the application will run although not correctly since the data layer has been removed but it does execute as expected instead of hanging. If we run Procmon and watch the probes the correct folders are searched and the images show as loading. But execution fails, either the application hangs or exits. If we move the assemblies to a 'special' folder such as Program Files or Documents, regasm the p

Slow load time of custom assembly on x64 compared to x86.

  
I am developing an application that automatically generates assemblies using the CSharpCodeProvider (.Net Framework 3.5).  These assemblies contain a single class with a very large number of local variables and methods.  After compilation I create an instance of this class (using Activator.CreateInstance) to be used elsewhere in the application.  When the application is deployed on a 32-bit system (tested on Win 7 Prof 32-bit and on Win XP) the CreateInstance method returns after 1 or 2 seconds, i.e. it first JITs the assembly before creating the instance.  However, on a 64-bit system (tested on Win 7 Home 64-bit, Win Server 2003 64-bit and Win Server 2008 64-bit) CreateInstance takes up to 5 minutes to return. Is there any reason why it would be that much slower on a 64-bit machine? I have tried many different options when compiling, such as setting the platform to x64, using the /optimize flag, etc, but none of these have made a difference. I also tried calling PrepareMethod on all the method in the class.  When I do this in the 32-bit environment, it takes approximately 10 seconds.  In the 64-bit environment it takes more than 3 minutes. As a last resort I tried ngen before constructing the object, but this made no difference in the execution time.

Mixed Mode assemblies

  
Does anyone have a good tutorial on how to make the compiler package a mixed-mode assembly?  Specifically:I have a piece of non-trivial C code maintained externally.  I would like to compile that and distribute it with a managed wrapper in a single assembly.  Im looking at the build files for a project which does something similar but right now im at a loss as to how to set this up. 

Load dynamically assembly with dependencies

  
I'm trying to download .dll by having some url (http://somedomain.com/myassembly.dll) and load it into appdomain. Once I download this assembly I can't load it into appdomain, because it has some dependencies. Some of these dependencies I can found on my local machine (such as .NET libraries), but some of them I have to download and load into appdomain. So there are several questions: 1. How to determine list of dependencies without loading assembly into appdomain (and by having only byte[] as assembly) 2. How to determine which of these dependencies can be found locally Thanks, Paul.
