I’m trying to run my application on my production server but I’m getting this error message when I try to load it:
“Could not load file or assembly ‘Microsoft.Bcl.AsyncInterfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ or one of its dependencies. The system cannot find the file specified.”
I did install the same package version and copied the missing DLL file to the appropriate directory, but the error persists. I’m not sure if the DLL file I’m using is the right one or if I’m missing something else. Here’s my server configuration:
Windows Server 2012 R2 Standard
.NET Framework version 4.7.2
Microsoft Visual Studio 2017 version 15.9
Here’s the relevant part of my web.config file:
I’m not sure what else to try. Any help would be greatly appreciated!
Could not load file or assembly 'Microsoft.Bcl.AsyncInterfaces' after updating all packages to .net core 3.0.

Hello there! I see you are having trouble with the missing assembly issue. Well, the error message you are seeing usually means that the application is looking for a specific assembly that it cannot find. In the case of the Microsoft.Bcl.AsyncInterfaces assembly, it is needed for the proper functioning of certain async methods.
To solve the problem, you need to make sure that the missing assembly is properly referenced in your code. First, try to find the assembly in your project’s reference list and make sure that the correct version is selected. If it’s not in the list, you can add it manually by browsing to the .dll file and selecting it.
If the above solution does not work, then try including the assembly in the solution output. You can do this by right-clicking on the assembly in the Solution Explorer and selecting “Properties”. Then set the “Copy Local” property to “True”. This will ensure that the assembly is copied to the output directory when the solution is built.
Another solution would be to make sure that the missing assembly is installed in the GAC (Global Assembly Cache). You can check if it’s installed by browsing to C:WindowsAssembly. If it’s not there, you can use the gacutil.exe tool to install it.
Finally, if none of the above solutions help, you can try updating your NuGet package manager to see if the missing assembly can be added from there. Use the command “Update-Package Microsoft.Bcl.AsyncInterfaces” in the Package Manager Console to update your Nuget packages.
I hope this helps you solve your issue! Remember, if none of the above solutions help, don’t hesitate to ask for help from fellow developers or support forums. Good luck and happy coding!
The issue you are facing seems to a common one with Microsoft BCL AsyncInterfaces. The most common cause for such errors are version mismatch or missing files. One possible cause of this error could be that the references of the dependent files are not set up correctly in your project.
To resolve this issue, one thing you can try is to reinstall the NuGet Package with the latest version of Microsoft BCL AsyncInterfaces. Another thing you can try is to check if all the dependencies are present in the project and if they are correctly referred to. You can also try clearing the NuGet package cache and then build the solution. This might help you resolve the error.
I hope this will help you resolve your issue. If you have any further questions or concerns, feel free to ask.
In addition to updating your NuGet packages, you can also try clearing your project’s cache in Visual Studio. Sometimes cached data can cause unexpected behavior, such as the error message you are receiving.
To clear your cache, close Visual Studio and navigate to the folder where your project is stored. You should see a folder named “bin” and “obj”. Delete both of these folders, as they contain cached data.
Then, reopen your project in Visual Studio and try building and running it again. This should rebuild the necessary files and hopefully solve your issue.
If clearing your cache and updating your NuGet packages do not work, you may need to try some other troubleshooting methods or seek help from a more experienced developer.
