[Solved] Compile error ILT0005 with Telerik package 2021.1.119.1

[G]

Ever since we upgraded to the latest Telerik package 2021.1.119.1 we get the following error when we compile in Release mode using .Net Native tool chain. I've redacted paths below.

ILT0005: 'C:\Users\<redacted>\.nuget\packages\runtime.win10-x64.microsoft.net.native.compiler\2.2.9-rel-29512-01\tools\x64\ilc\Tools\nutc_driver.exe @"C:\<redacted>.rsp"' returned exit code 1

Hello Giancarlo,

That error is unrelated to Telerik UI for Xamarin. Here is a thread from Microsoft that explains one of the most common reasons.

• .Net Native raises ILT0005 when compiling UWP project in Release configuration - Microsoft Q&A.
• c# - Xamarin UWP release mode Error - ILT005 returned exit code 1 - Stack Overflow
• Issues when compiling very big UWP applications (curia.me)

Note: If you are using some sort of GitHub Actions or Azure DevOps to do the build, you will need to increase the memory of the agent/runner. .NETNative build uses a huge amount of memory. Here is an example of how increase the pagefile for the VM that runs the build.

steps:
    - name: Configure Pagefile
      uses: al-cheb/configure-pagefile-action@v1.2
      with:
        minimum-size: 32GB
        maximum-size: 32GB
        disk-root: "C:"

If that doesn't help, here are some other articles:

• https://stackoverflow.com/questions/37593470/net-native-out-of-memory 
• Error on UWP release package creation: ILT0005 nutc_driver.exe exit code 1 - Developer Community (visualstudio.com)
• Error when run app in release in UWP — Xamarin Community Forums

Worst Case

If you still cannot get past it, then I recommend you uninstall the NuGet package and directly reference the individual DLLs instead. That will keep the compilation size down. Please pay close attention to the required dependencies for each control.
