Hello Vijay Pratap Singh

Azure Functions where the build process creates a nested bin folder. This can happen due to certain build configurations or project settings

This issue affects many scenarios with configuration files. Only when using Azure Functions, config files tagged with CopyToPublishDirectory are copied to bin/output but the assembly execution path is bin/output/bin.

In other words:

classic .NET app: assembly execution path == config files path
Azure functions: assembly execution path != config files path

https://github.com/Azure/azure-functions-vs-build-sdk/issues/518

To resolve the issue try to make the file as Copy Always:

<None Update=

In VS, Click on the file > Properties > Change Copy to Output Directory > Copy Always.

Hi @Andriy Bilous
The solution you provided is not working in my case.
Problem I am facing is that I have installed new relic APM service in my project, after publishing the azure function project to the 'Azure Function App' it creates two directories, one with half the dlls and one with some missing dlls, this is creating a serious reference issue with my project after deployment.

Half dlls is in this directory
C:\home\site\wwwroot\newrelic
and rest half is in the below directory
**C:\home\site\wwwroot\bin\newrelic
**
Every time I need to copy dlls from one folder to another folder, which is not the valid solution.
Can you help me in this problem?

See: Azure Functions monitoring integration

For the nested bin is likely due to your project configuration. Check your csproj

YAMLCopy

<PropertyGroup>
