[Bug] Microsoft.Identity.Client doesn't support IL Trimming

[azchohfi]

.NET6 added IL Trimming (https://devblogs.microsoft.com/dotnet/announcing-net-6/#il-trimming) Unfortunately, MSAL.Net doesn't support it.

Which version of MSAL.NET are you using? Microsoft.Identity.Client 4.44.0

Platform .NET 6

What authentication flow has the issue?

• Desktop / Mobile
  • [X] Interactive
  • [ ] Integrated Windows Authentication
  • [ ] Username Password
  • [ ] Device code flow (browserless)
• Web app
  • [ ] Authorization code
  • [ ] On-Behalf-Of
• Daemon app
  • [ ] Service to Service calls

Is this a new or existing app? This is a new app or experiment.

Repro

A very simple .NET 6 app:

string[] scopes = new string[] { "user.read" };
var clientId = "...";
var app = PublicClientApplicationBuilder
    .Create(clientId)
    .WithRedirectUri("http://localhost")
    .Build();
var accounts = await app.GetAccountsAsync();
try
{
    result = await app.AcquireTokenSilent(scopes, accounts.FirstOrDefault())
                .ExecuteAsync();
}
catch (MsalUiRequiredException)
{
    result = await app.AcquireTokenInteractive(scopes)
                .ExecuteAsync();
}

With:

    <PublishTrimmed>true</PublishTrimmed>
    <PublishSingleFile>true</PublishSingleFile>

And built with: dotnet publish --self-contained -r win-x64 /p:Configuration=Release /p:TrimmerSingleWarn=false

Will produce dozens of warnings/errors, such as:

  Optimizing assemblies for size, which may change the behavior of the app. Be sure to test after publishing. See: https://aka.ms/dotnet-illink
C:\Program Files\dotnet\sdk\6.0.400-preview.22301.10\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.ILLink.targets(109,5): error NETSDK1144: Optimizing assemblies for size failed. Optimization can be disabled by setting the PublishTrimmed property to false.

Expected behavior No build errors or warnings when building a self-contained exe.

Actual behavior Multiple errors, and very hard to workaround/fix manually.

Possible solution Most errors seems related to JSON deserialization, and .NET6 now supports source generation for this, so it should be possible to support this.

[bgavrilMS]

Excellent bug. Just so happens that we are also exploring this area, as we want to make MSAL compile with NET7's AOT compiler. Here's are the notes that @pmaytak wrote on the subject.

Problem statement:

• Reflection-based code does not work well with Ahead-Of-Time (AOT) compliers. As a workaround, usually a whole assembly that uses reflection needs to be added into the package increasing final package size.
• Estimate the work of moving JSON serialization to not use reflection in MSAL.

Possible solutions:

1. Update current Newtonsoft JSON.NET implementation via flags to disable reflection as was done for Unity. a.

• For Unity related work, build flags were added to exclude reflection code in JSON.NET code for .NET standard and some .NET Fx targets.
• The changes were based on this AOT fork of JSON.NET - jilleJr/Newtonsoft.Json-for-Unity: Newtonsoft.Json (Json.NET) 10.0.3, 11.0.2, 12.0.3, & 13.0.1 for Unity IL2CPP builds, available via Unity Package Manager (github.com).
• This work would include updating our JSON.NET code to probably match the AOT fork. If it's not clear what specifically needs to be changed, then may require running MSAL and testing where it breaks.
• Would also have to test specifically on targets which will be compiled for AOT.
• ETA can be as short as a day, if what was done for Unity already works or minimal flags need to be added.

2. Add System.Text.Json package for supported targets, while keeping JSON.NET for older targets ? a. First need to research System.Text.Json feature and framework availability. i. Source generation is only for .NET 5+. How to choose reflection or source generation in System.Text.Json | Microsoft Docs/ ii. Differences with JSON.NET need to be verified. Migrate from Newtonsoft.Json to System.Text.Json - .NET | Microsoft Docs b. Need to look over what existing features we use from JSON.NET. i. There are 71 references to JSON.NET namespace in MSAL and tests projects. c. Ideally individual usages should be consolidated in JSON helper class and used from there. d. Add pre-processor flags to load the relevant implementations based on the target framework. e. Existing tests should be enough, but coverage should still be verified. f. ETA is at least 3+ days. Research of current used functionality is the most important part. Code changes should be easy once migration steps are defined.

3. Replace Newtonsoft.Json with System.Text.Json source code from https://github.com/dotnet/runtime/tree/main/src/libraries/System.Text.Json. a. The current System.Text.Json minimal requirements might not be a functional limitation and the code might simply work in 4.5.2 since it works in net 4.6.1 b. Same as above, except JSON.NET code will be removed.

4. Use System.Text.Json generator code a. We could pull the reflection less code generator into the repo and run it outside of minimal generation

5. Write your own code generation based on contract classes: a. Move json manipulation into data contract classes or multi b. Create a build task that would generate json string serializers using JsonDocument writers etc.

One of the challenges in estimating time are the unknowns that need to be researched - what exactly needs to be excluded in JSON.NET and making sure System.Text.Json supports everything that we use from JSON.NET.

Hey @Sergio0694, do you happen to be aware of any common pitfalls for the approaches above? cc/ @michael-hawker

[Sergio0694]

Just want to clarify this:

"Reflection-based code does not work well with Ahead-Of-Time (AOT) compliers."

This is not correct. There's nothing inherently problematic with AOT and reflection. The issue is not using AOT, the issue is the package not using proper trimming annotations to inform the linker when performing trimming. You could publish a non-trimmed fully AOT binary with no code changes, and there would be no problems whatsoever.

Just to give an example, we use reflection in several places in the Microsoft Store, and we also use Newtonsoft.Json. That's not an issue with AOT at all (the Store is compiled with .NET Native, so it's 100% AOT, and also trimmed). It's just a matter of preserving the right metadata to make reflection work. In our case, we had to manually add runtime directives where needed. In this case, since you're on .NET 6+, you have trimming annotations at your disposal, so you can leverage them to inform the linker.

Essentially, removing reflection is of course nice as it helps performance and binary size, but it is not required.

A first, low-risk approach should be to just enable trimming for the assembly and add the necessary annotations to eliminate trimming warnings. This should be done regardless of any other changes you might want in the future, as it's just a baseline you should start from. Then, definitely, moving to System.Text.Json and source generators would be nice to have 🙂

[michael-hawker]

@bgavrilMS what's the minimum target framework you're looking to support?

According to the support policy here:

Support for .NET Framework 4.5.2, 4.6, and 4.6.1 ended on April 26, 2022. Customers and developers must have completed the in-place update to .NET Framework 4.6.2 or later by April 26, 2022 to continue receiving technical support and security updates.

As it'd be nice to just switch over to System.Text.Json as its continually getting performance improvements.

[pmaytak]

@Sergio0694 you're right. I think initially that was written to mean as you have to pay attention to reflection-based code when using AOT.

@michael-hawker net45 is one of the targets that we still support but not supported by System.Text.Json. And also perhaps some of the older Xamarin targets might not be supported. But we're thinking deprecating support for those, so we should be fine to use System.Text.Json. One thing that's not clear to me yet, is if the source generation is only supported in net6+, or in earlier frameworks via the package also (if so, it would suit us well).

[michael-hawker]

@pmaytak source generators in general w/ .NET need to be built with .NET 6+, but the outputted code doesn't have to be limited to run on .NET 6. We use them in the Toolkit to interop with .NET Standard 2.0 and UWP for instance.

According to the intro dev blog here, the System.Text.Json generators should behave similarly:

The source generator is compatible with other target framework monikers (TFMs) aside from .NET 6.0, that is .NET 5.0 and lower, .NET Framework, and .NET Standard. The API shape of the generated source code is consistent across the TFMs, but the implementation may vary based on the framework APIs that are available on each TFM.

[bgavrilMS]

About dependencies

• MSAL is compiled only on TFMs compatible with netstandard 2.0 and on net45 TFM. We are ok with dropping support for net45
• If we were to take on the System.Text.Json dependency, we would need to move to a versioning system similar to Microsoft.Extensions* libraries, i.e. we would need to explicitly define a TFM for each new version of .NET. Something like:

MSAL tfm	System.Text.Json
NET 4.6.2	4.*
NetStandard	4.*
NET 5	5.*
NET 6	6.*

About Json operations

Apart from the regular serialize / deserialize operations, MSAL uses a more advanced serialization technique when it comes to the token cache. MSAL will preserve unknown JSON nodes (think distributed system, where node A uses MSAL 4.1 and node B uses MSAL 4.2).

As such, it might be easier to make changes to existing newtonsoft serializer.

[tipa]

Please also consider that the Newtonsoft.JSON dependency is extremely large. Multiple megabytes, especially when AOT is enabled (which is a must in iOS apps). Using System.Text.Json would significantly reduce the app size, which does matter especially for mobile apps. The MS Graph library (which I assume is commonly used in combination with MSAL) already did the switch to System.Text.Json

Would it be possible to re-open this feature request?

[bgavrilMS]

CC @pmaytak

[azchohfi]

Working on using System.Text.Json. Got most of the tests passing again. Sending PR soon.

[bgavrilMS]

@michael-hawker - can you please elaborate on this? MSAL is built against .NET 4.6.x, .NET Core App 2.1 and .NETStandard 2.0. The build scripts today I believe use .NET SDK 3.1

To ensure code generators work, what do we need to do? Ensure that the build machines use .NET 6 SDK ? Or add NET 6 target framework to MSAL explicitly?

[michael-hawker]

@bgavrilMS all you should need is for the build environment to install the .NET 6 SDK (for instance with GitHub Actions it'd be):

      - name: Install .NET 6 SDK
        uses: actions/setup-dotnet@v1
        with:
          dotnet-version: '6.0.301'

Though if you're still building for an older target netcore app, you may need to install both SDKs? But you don't have to change the multi-targeting unless you want to make specific optimizations for newer platforms (like .NET 6 wouldn't need the System.Text.Json NuGet package as it's included w/ .NET itself now).

Net Core App 2.1 is out of support now, so it looks like Alex updated to 3.1 in his PR here as well

[mjcheetham]

One of the blockers for us (Git Credential Manager) from dropping .NET Framework on Windows (and going .NET6/7 etc) would be the ability to publish our app trimmed. Since MSAL is a hard dependency for us, this work would be really helpful for us! Would love to publish AOT compiled too in .NET 7 if MSAL can work.

[charlesroddie]

I believe this is still not solved. We publish an ios app with NativeAOT and get these warnings:

@charlesroddie Do you target .NET 8, net8.0-ios?

[charlesroddie]

Yes sorry net8.0-ios in this build.

[bgavrilMS]

Please open a new bug on the library @charlesroddie . We've done the work to move from Newtonsoft to System.Text.Json only for our net6 and net6-windows target, we did not do it for net6-ios / net6-android targets.
