[wasm] Endian fix for Webcil #92274

saitama951 · 2023-09-19T13:20:50Z

'dotnet new blazorwasm' command failed on s390x and was throwing a not implemented exception

The issue was with with the WebCil writer and reader, specific endianness conversions relating to the webcil payload were not implemented for big endian machines.

We considered fixing the generic implementation, but there were only two structures in use: WebcilHeader and WebcilSectionHeader, so it was easier to handle them explicitly.

Thanks. Can you try removing the #if if it compiles? This function might be available on all frameworks (unless I'm missing something).

Thanks for pointing that out. I have done the same for the WriteStructure as well and hence removing the endian checks for net472 as well. making it generic :)

It's a little more subtle than just having the API on net472. Because this code is used in an MSBuild task that might be called from a build in Visual Studio, the API has to be in whatever old version of the out of band assembly is already loaded in to the MSBuild process that invokes the task.

@saitama951 Hmm... actually we might also need to add this:

<PackageReference Include="System.Memory" Version="$(SystemMemoryVersion)" />

to src/tasks/Microsoft.NET.WebAssembly.Webcil/Microsoft.NET.WebAssembly.Webcil.csproj
