✅ "Platform linker not found." error with NativeAOT (Visual Studio Insiders)

I want to compile with NativeAOT: * I added <PublishAot>true</PublishAot> property to my .csproj file * I am not using reflection or any other feature that would break my app * I have the "Desktop development with C++" workload installed * I open "x64 Native Tools Command Prompt for VS Insiders" and where link command does seem to print a correct path

C:\Program Files\Microsoft Visual Studio\18\Insiders\VC\Tools\MSVC\14.50.35717\bin\Hostx64\x64\link.exe

C:\Program Files\Microsoft Visual Studio\18\Insiders\VC\Tools\MSVC\14.50.35717\bin\Hostx64\x64\link.exe

I am using this command on my Windows machine:

dotnet publish ./MyProject.csproj -c Release -r win-x64 --self-contained true -p:PublishAot=true

dotnet publish ./MyProject.csproj -c Release -r win-x64 --self-contained true -p:PublishAot=true

However, I get this error in the end:

Why can't it find the linker? What am I missing? It used to work back when I was using Visual Studio 2022, which might be a coincidence but I suspect it is to do with the IDE itself

yes, it's a bug in the way Native AOT finds the tools unfortunately, it won't detect VS 2026 one way to fix is is to target .NET 10 instead another way to fix it is to wait until next month when the fix will be made available for .NET 9 you can also fix it by going into your NuGet global pakcages cache, and editing this file

microsoft.dotnet.ilcompiler\9.0.11\build\findvcvarsall.bat

hey, I actually came across you while searching if this question had already been asked before in this server https://discord.com/channels/143867839282020352/169726586931773440/1130516073989558352 (year 2023) I was hoping so much you'd still be active and see my post 😄

you need the Windows SDK and the regular MSVC build tools
