Use ReadyToRun or ahead-of-time (AOT) Compilation

.NET ReadyToRun (R2R) is a form of ahead-of-time (AOT) compilation.

Enabling ReadyToRun compilation during deployment might violate tampering protection and result in the following exception.

Exception: Unhandled exception. IronSoftware.Exceptions.LicensingException: IronPdf, Version=2024.2.0.2, Culture=neutral, PublicKeyToken=94e1c31412563c75 assembly is not authentic. Please try to reinstall the nuget package

Reason

According to Microsoft documentation, the SDK will precompile the assemblies that are distributed with the application. For self-contained applications, this set of assemblies will include the framework. It's important to note that C++/CLI binaries are not eligible for ReadyToRun compilation.

Solution

To exclude specific assemblies from ReadyToRun processing, use thelist.

<ItemGroup>
    <PublishReadyToRunExclude Include="IronPdf.dll" />
</ItemGroup>
