Could not load file or assembly 'Microsoft.ApplicationInsights, Version=2.12.1.36699, Culture=neutral or one of its dependencies

Question

My application has a nuget package called CustomLogger(created by us). CustomLogger has Microsoft.ApplicationInsights nuget package installed in it with version 2.12.1

Today I installed another nuget package called HistoryStats(created by us) which also has Microsoft.ApplicationInsights nuget package installed in it but with newer version 2.14.0

After installing the second nuget, my application is failing with below error

Could not load file or assembly 'Microsoft.ApplicationInsights, Version=2.12.1.36699, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified

Here is my reference in .csproj file

<PackageReference Include="CustomLogger" Version="2020.2.19.3" />
<PackageReference Include="HistoryStats" Version="2020.4.27.1" />
<PackageReference Include="Dapper" Version="2.0.30" />
<PackageReference Include="Microsoft.Azure.Storage.Blob" Version="11.1.1" />
<PackageReference Include="Microsoft.Azure.Storage.Common" Version="11.1.1" />
<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.1" />

Is there a way to refer different Microsoft.ApplicationInsights version for different nuget package ?

What type of application is it? In WPF in the app.config you can use assemblyRedirect to point all references to one version, but I have not used these on other project types. — Ryan Thomas, Jul 14 '20 at 14:10
@RyanThomas - Its a Azure function App, there is no `app.config` file. — Pரதீப், Jul 14 '20 at 14:11
Ah okay. Does this help? https://stackoverflow.com/questions/38093972/azure-functions-binding-redirect — Ryan Thomas, Jul 14 '20 at 14:14

For a WPF application in the app.config under the "runtime" element you can add an assembly redirect accordingly. Example below, you will need to change the numbers to suit.

I am not used these on other project types, but imagine the process is similar.

<dependentAssembly>
    <assemblyIdentity name="Microsoft.ApplicationInsights" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.12.1.36699" newVersion="2.12.1.36699" />
</dependentAssembly>

For Azure Functions this question may help.
