dependencies" problems. Additional information: Could not load file or assembly 'Microsoft.Practices.Unity, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) I have no idea what is causing this or how I could debug it to find the cause. I've done a search in my solution catalogs .csproj files, and every where I have Unity I have: Reference Include="Microsoft.Practices.Unity, Version=2.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" Can't find any reference c# could not load file or assembly operation is not supported anywhere which goes against 1.2.0.0 in any of my projects. Any ideas how I should go about solving this? I would also appreciate tips on how to debug problems like this in general. c# .net reference compiler-errors share|improve this question edited Aug 29 '12 at 9:54 abatishchev 56.8k56214353 asked Dec 17 '10 at 11:13 ronag 18.9k1375152 1 Could any of your referenced assemblies be using some stuff in old Unity library? –decyclone Dec 17 '10 at 11:19 2 Probably... but how can I find which assemblies? I have a lot of projects in my solution and a lot of potential suspects... trial and error bruteforce seems a bit hopeless... –ronag Dec 17 '10 at 11:21 You only have to look into the referenced assemblies in the project for which you get this error. –decyclone Dec 17 '10 at 11:26 3 It's not the assembly reference, you reference version 2.0. But at runtime, the CLR is finding 1.2, an old version. If you don't see that old DLL in your build directory then use Fuslogvw.exe to find out how the CLR found this old copy. –Hans Passant Dec 17 '10 at 11:47 1 Look at your project's bin folder and see if your project's dll has a conflict in it's name. Just delete that one and then Rebuild your solution. That worked for me. –coggicc Jul 30 '15 at 20:48 | sh

21, 20077 0 0 0 This is one of the most irritating build errors a developer might see, especially while setting up an existing .NET application on a fresh machine. https://blogs.msdn.microsoft.com/sayanghosh/2007/04/21/solution-to-could-not-load-file-or-assembly-or-one-of-its-dependencies-access-is-denied/ I have found one solution that works always. Go to "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files" ( Modify the framework version, root directory etc according to your environment. ) Now, right-click and open up the Security tabs for this folder. Grant "Full control" to the ‘users' group. (Modify will also work, thought I didn't try it out) However, it this is a security problem for your environment to could not grant full control to all users in Users group, another Solution could be to put the concerned assemblies lo GAC which I avoided as it was not logical to put the assemblies into GAC in my scenario.
