Could not load file or assembly 'DotNetOpenAuth.AspNet'

Question

I am getting below error whenever I am running my project. This is happening from the time I installed DotNetOpenAuth.

Could not load file or assembly 'DotNetOpenAuth.AspNet' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileLoadException: Could not load file or assembly 'DotNetOpenAuth.AspNet' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'DotNetOpenAuth.AspNet' could not be loaded.

=== Pre-bind state information === LOG: DisplayName = DotNetOpenAuth.AspNet (Partial) WRN: Partial binding information was supplied for an assembly: WRN: Assembly Name: DotNetOpenAuth.AspNet | Domain ID: 2 WRN: A partial bind occurs when only part of the assembly display name is provided. WRN: This might result in the binder loading an incorrect assembly. WRN: It is recommended to provide a fully specified textual identity for the assembly

I also get below warning while building the project.

C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets(1697,5): warning MSB3277: Found conflicts between different versions of the same dependent assembly that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed.

There is absolutely no information as to what is going wrong here. Can someone help me debug as to what is the issue. I am trying to fix this from past 2 days but had no luck whatsoever.

Answer 1

Personally, I had to go Tools > NuGet Package Manager > Manage NuGet Packages for Solution... and update the DotNet*.* packages. Note that the solution I am working on is a group project hosted on an SVN. If one person updates their packages it may affect other users until they also update.

Answer 2

According to your packages.config file, you have multiple versions of each package installed. Your site won't function properly until you've cleaned this up--especially with respect to WebAPI and MVC. Your best bet is to do a Clean, remove all of these non-client-side packages (you can leave jQuery and other client-side libraries), and re-add whichever version you need. You only want 1 version of each when all is said and done.

If you really, really wanted to make this work without cleaning up your packages.config, you could setup assemblyRedirection in web.config (See here: http://msdn.microsoft.com/en-us/library/7wd6ex19(v=vs.110).aspx) and point all requests for 1 version to the other.

You'll need to check the WebPages, MVC and WebAPI version references mentioned in all web.config files in your web app to be sure they are referring to the correct versions as well.

Answer 3

If you installed it whit Nuget it should install all references needed.
