Description

I've tried enabling recently added <WasmStripILAfterAOT> (dotnet/core#8439 (comment)), but it breaks the application and results in slightly larger build size (5.05MB vs 5.06MB).

Reproduction Steps

  1. Clone https://github.com/Elringus/DotNetJS/tree/feat/revamp/Samples/App
  2. Under App directory run npm install
  3. Run dotnet publish backend
  4. Run npm run dev
  5. Open browser with the reported dev server address
  6. Observe the app is working and check binaries size under App/public/bin (5.05MB on my end)
  7. Add <WasmStripILAfterAOT>true</WasmStripILAfterAOT> to App/backend/Backend.WASM/Backend.WASM.csproj properties
  8. Run dotnet publish backend to re-build the solution
  9. Run dev server and check the app and binaries size again

Expected behavior

App works as before and binaries size is at least not larger than before.

Actual behavior

Binaries size is slightly larger (5.06MB on my end) and app crashes with the following log:

Issue Details

Description

I've tried enabling recently added <WasmStripILAfterAOT> (dotnet/core#8439 (comment)), but it breaks the application and results in slightly larger build size (5.05MB vs 5.06MB).

Reproduction Steps

  1. Clone https://github.com/Elringus/DotNetJS/tree/feat/revamp/Samples/App
  2. Under App directory run npm install
  3. Run dotnet publish backend
  4. Run npm run dev
  5. Open browser with the reported dev server address
  6. Observe the app is working and check binaries size under App/public/bin (5.05MB on my end)
  7. Add <WasmStripILAfterAOT>true</WasmStripILAfterAOT> to App/backend/Backend.WASM/Backend.WASM.csproj properties
  8. Run dotnet publish backend to re-build the solution
  9. Run dev server and check the app and binaries size again

Expected behavior

App works as before and binaries size is at least not larger than before.

Actual behavior

Binaries size is slightly larger (5.06MB on my end) and app crashes with the following log:

I'm having this issue in production .NET8, AOT WASM. Happens regardless whether WasmStripILAfterAOT is on or off. The console errors start:

MONO interpreter: NIY encountered in method .ctor

dotnet.runtime.8.0.0.14kkjimq5k.js:3 Error: [MONO] * Assertion: should not be reached at /__w/1/s/src/mono/mono/mini/interp/interp.c:3863

Which repeats 4 times with other stack traces, and then ultimately:

ExitStatus {name: 'ExitStatus', message: 'Program terminated with exit(1)', status: 1}
message
:
"Program terminated with exit(1)"
name
:

status

:
Object

Interpreted works fine. AOT also worked fine in .NET6.

Can confirm the same issue is still reproducing in final .NET 8.0. Was the mentioned PR merged to 8.0 or it's postponed to 9.0? (the PR is missing milestone)

The fix was merged recently. Unfortunately, it didn't make it to the .NET8 GA. It will for sure be in .NET9. It might be able to be released as part of .NET8 service1. But I can't guarantee that right now.

Could you try to build your app after deleting all the build artifacts of your app and turning off WasmStripILAfterAOT?

@fanyang-mono apologies, I stand corrected. It DOES work properly when WasmStripILAfterAOT is off. I had to more thoroughly clear the build artifacts. So it likely is the same issue. Thanks for the tip.

Do we know the qualitative cause and is it something we can try to avoid until the fix makes it into production? Or is WasmStripILAfterAOT just broken entirely?

@legistek Thanks for confirming and trying out this new feature. Unfortunately, the initial release of WasmStripILAfterAOT is only capable of handling simple apps. If your app ran into this issue, you would have to avoid using it, until we release the fix (#90436).

@fanyang-mono gotcha thank you. Stripping IL isn't critical now that I can get AOT working without it.

@fanyang-mono I am hitting this error without stripping on a clean debug build. I have cleared out the bin and obj folders completely prior to making the build to rule out the case that legistek describes above. This is the entire log:

@sschoener Thanks for reporting this issue. This should not happen to a fresh build with WasmStripILAfterAOT setting to false. Could you please share a reproduction app?

Please find the project here: BlazorLineFilter.zip

It is a tiny project created from the Blazor WebAssembly template. It consists of a single page with some JavaScript-interop to open/close files on the users file system. To reproduce, open the solution, build for Debug (Any CPU). Then start with https. Also note that on my machine this build frequently takes ~60min (System.Private.CoreLib.dll.bc by itself takes 10minutes, aot-instances.dll.bc takes 41 minutes -- likely because of the lack of stripping) and can lock up the entire system because clang++ happily takes so much memory that you are in memory hard fault hell, so you may have to give it some time :). -- Visual Studio version is 17.8.3, dotnet --version is 8.0.100.

Let me know if I can be of further assitance.

Publishing with WasmStripILAfterAOT=false works

dotnet publish UI.csproj -c Release -p:RunAOTCompilation=true -p:WasmStripILAfterAOT=false

But this crashes with MONO interpreter: NIY encountered in method .ctor

dotnet publish UI.csproj -c Release -p:RunAOTCompilation=true -p:WasmStripILAfterAOT=true

The latter does produce noticeably smaller files, which is nice, e.g. dotnet.native.wasm.gz went from 3.7MB to 2.5MB. Huge improvement!

@fanyang-mono you mentioned that it should be fixed in #90436. I see that PR is merged now. When is it going to be release? That size improvement would be great to have.

Just encountered this myself too. exactly the same issue as @iSeiryu describes above.

Looks like we have to wait for .NET 9 for the fix? No chance of getting it in a .NET 8 update??

UPDATE: Running AOT + WasmStripILAfterAOT publish of our Blazor WASM Standalone app AS ADMINISTRATOR seemingly broke my .NET install altogether... I cannot even start our ASP.NET app anymore (separate from WASM app) in debug mode. I get System.InvalidProgramException: Common Language Runtime detected an invalid program. at ... errors every time. I tried running .NET SDK repair but no luck. I will now try a full remove of .NET 8 using Visual Studio Installer and then reinstall it...
Amazing how this one option could mess up my whole environment!? The only reason I ran it as admin in the first place was because it was complaining about permission issues in the dotnet installation folder. It did sound very suspicious as it wanted to "move" something....

My Windows is completely messed up from this... I cannot get it fixed. Created issue #98041
EDIT2: After 5 hours I got it solved... This is a MAJOR issue if this is what caused it initially. Hope to see a fix asap! Please see my linked issue for details on my specific persistant problem and solution

Sorry about the delay. The fix has been shipped as part of .NET9 Preview1. Please download the latest .NET from https://dotnet.microsoft.com/en-us/download/dotnet/9.0 to see if you issue has been resolved.

Closing this now, as all the issues related to WasmStripILAfterAOT should have been fixed.
