[Client bug]: Tavis.UriTemplates loading issue when using Microsoft.Graph@5.0.0 and net472

[jairbubbles]

Describe the bug

When using latest NuGet package, it fails to load Tavis.UriTemplates.dll:

System.IO.FileLoadException: Could not load file or assembly 'Tavis.UriTemplates, Version=2.0.0.0, Culture=neutral, PublicKeyToken=5be2d48fa8a60581' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

It seems related to #1439.

It looks like the reference is:

But the assembly name in package is:

To Reproduce Steps to reproduce the behavior:

1. Use this .csproj:

   <Project Sdk="Microsoft.NET.Sdk">
   <PropertyGroup>
       <OutputType>Exe</OutputType>
       <TargetFramework>net472</TargetFramework>
       <LangVersion>latest</LangVersion>
   </PropertyGroup>
   <ItemGroup>
       <PackageReference Include="Microsoft.Graph" Version="5.0.0" />
   </ItemGroup>
   </Project>

   With program.cs:

   
   using System;
   using System.Collections.Generic;
   using System.Threading;
   using System.Threading.Tasks;
   using Microsoft.Kiota.Abstractions;
   using Microsoft.Kiota.Abstractions.Authentication;

var authProvider = new BaseBearerTokenAuthenticationProvider(new TokenProvider()); await authProvider.AuthenticateRequestAsync(new RequestInformation());

class TokenProvider : IAccessTokenProvider { public Task GetAuthorizationTokenAsync(Uri uri, Dictionary<string, object> additionalAuthenticationContext = null, CancellationToken cancellationToken = new()) => Task.FromResult(string.Empty);

public AllowedHostsValidator AllowedHostsValidator { get; } = new();

}

2.  Run
3.  Observe the loading exception

**Expected behavior**

No exception ;-)

**Client version**

5.0.0

Thanks for raising this @jairbubbles

Just to confirm, any chance you can still replicate this with version 5.1.0?

[jairbubbles]

I'll check!

[jairbubbles]

Sadly yes, I can reproduce with version 5.1.0.

The package dependencies did not change so we get the exact same behavior.

[andrueastman]

Any chance you can share a sample repro project to help us understand this better? We are having trouble replicating this as the build works from our end.

[jairbubbles]

You mean in a zip file? The files in the description are enough to get it. I just hit F5 to get the exception.

That would be helpful. As from my end, the build runs successfully.

[jairbubbles]

Here you go:

GraphApiTest.zip

• Unzip
• dotnet run
• 💥

(My dotnet version is 7.0.102)

[andrueastman]

Thanks for this @jairbubbles,

Unfortunately, I'm still unable to replicate this. This builds fine on my end with VS 2022 and dotnet SDK 7.0.201.

Any chance this could be resolved by deleting the contents of the bin directory? Or possibly updating the .NET version?

[jairbubbles]

It builds fine, the execution is problematic right ?

[andrueastman]

That's not the case, the code is able to execute without issue from my end.

[jairbubbles]

I'll check with my colleagues if they can reproduce and get back to you, thx !

[jairbubbles]

Ok so I finally understand what's going on, after removing Tavis.UriTemplates from my global package cache and use nuget.org as my main NuGet source I no longer have the issue.

It seems that we have a different version cached in our internal NuGet package 😰

Version on nuget.org:

Version on our internal Nuget server:

Could it be that the package was republished? I'll check if it wasn't republished internally as I've already seen that once. It shouldn't happen but you know, mistake happen 😉

Sorry for wasting your time!

[andrueastman]

No worries @jairbubbles,

Thanks for confirming
