Could not load file or assembly 'Microsoft.AspNetCore.Http.Extensions, Version=3.1.0.0 in windows 10 machine

I am trying to run my Dotnet-Core web Api project in windows 10 machine. But I am facing runtime error. I 'm not allowed to change the Application nuget version too
>fail: Microsoft.AspNetCore.Server.Kestrel[13]

The answer here lies in - BadImageFormatException. One of these
Your app is compiled for one architecture (x64 or x86) but your Web Server pool runs different one
One of the 3rd party DLLs is of incompatible architecture (your case)
One of your DLLs is of incompatible architecture.
DLL is compiled for the wrong platform. e.g. running DLL compiled for .net4.8 in the .netcore (your case)

System.BadImageFormatException' occurred in your application(E.g. MyApplication.exe)

I am using Windows Application to communicate with Oracle 11g database to fetch some data. Oracle database was installed on the X64 bit system.
My Application builds successfully on my system (the x86 bit) with x64 bit dlls of Oracle. But when I run application below mentioned errors occurred.
An unhandled exception of type 'System.BadImageFormatException' occurred in your application(E.g. MyApplication.exe)
Additional information: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.
I had tried different ways to resolve this issue but still unable to found a solution for same. Please help me to resolve this issue.

You are trying to load a 64bit DLL from a 32 bit process or vice versa. Make sure the DLLs you want to load have the same bitness as your process.

Could not load file or assembly System, Version=2.0.5.0 in .NET 4 MVC 4 application

Been searching for ages, can't find anything helpful. Here is the exception I'm getting:
Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

This applications works fine on the test server but is throwing this exception on the production server. As you can see, the StructureMap code is what is causing the exception.
I had to convert this app to .NET 4 from 4.5 because 4.5 wasn't installed on the production server. After the conversion, the app still works fine on my local machine and the test server.
I have already set the Copy Local to True for the System assembly, but since the referenced version is 4.0.0.0 and not 2.0.5.0, I this made no difference.
Let me know if any more info is needed. Any help you may be able to provide is appreciated.

Make sure your .NET framework is patched. Microsoft released patches to .NET to allow Portable Class Libraries to properly find the appropriate runtime (KB2468871). If you are seeing the above exception (or something like it), it means you're missing the latest .NET framework patches.

Edit the web.config file to remove the reference, which is not required for normal operation:
1 - Open the web.config file in the root of your site
2 - Find the following line and comment it out():xxxxx-is your assembly name.
<add assembly="xxxxx", Version=2.0.5.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
3 - Save and close the web.config file and try again

I found that it was the "await" and "async" that where giving me trouble.
I had Windows XP SP3 with only .NET 4.0, but had to update it to .NET 4.0.3 using KB2600211 - this wasn't updated automatically through Windows Update when .NET 4.0.3 came out because the computer is off-grid.

I just want to share another solution from here that solved the problem on my development machine: installing Silverlight 5 SDK (only 11.2MB at the time of writing this post) was enough to make everything working.

Install Microsoft® Silverlight® 5 SDK from the following link. It resolves and works fine for me.
SDK download

Starting from a machine configuration that only had VS2017 and Silverlight 5 SDK on it, I installed VS2015 on top of that. This is when I started getting the System.Core and System.Windows problems.
When I uninstalled VS2015 and re-installed Silverlight 5 SDK, these problems went away.

UNC Path and Unhandled Exception: System.BadImageFormatException in C#

I compiled the whole project with x86 platform target. It is working fine when I copy .exe and the reference dlls on to the server and run .exe from server cmd window.
Our requirement is to copy the exe and dlls onto some network path and execute the exe on the server using UNC path. When I execute using UNC path, I am getting the error:
Unhandled Exception: System.BadImageFormatException: Could not load
file or assembly 'XXXX, Version=3.0.10.19399, Culture=neutral,
PublicKeyToken=null' or one of its dependencies. An attempt was made
to load a program with an incorrect format.
File name: 'XXXX, Version=3.0.10.19399, Culture=neutral, PublicKeyToken=null'
WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
Can someone help?

I'm just guessing now, but I would probably blame the path itself - it's most likely "untrusted", reason unknown. Enable Assembly Bind Logging (tip: google :) ) to figure out what's happening

Running Windows Update through wuapi.dll

I've added a reference to Interop.WUApiLib in my project, a console application. I'm trying to test out silently running updates on virtual machines but its not going so well. When I try to run the console app, it immediately crashed with the following error:
Unhandled Exception: System.IO.FileNotfoundEXception: Could not load file or assembly 'Interop.WUApiLib, Version=2.0.0.0, Culture=nuetral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. File name: 'Iterop.WUApiLib, Version=2.0.0.0, PublicKeyToken=null' at WindowsUpdateconsoleTest.Program.Main(String[] args)
I've checked the version on wuaueng1.dll and its 5.3.3790.5512, so WUA should be installed. I'm developing on Windows 7, the virtual machines are on Windows XP Service Pack 3. My local machine(which appears to run it fine is on a later version of wuapi.dll). Is that the issue? Or is something else going on?
I would really like to not have to call powershell scripts on these machines if I can avoid it.
