- modularized dotnet.js
- By using emcc options `MODULARIZE` and `EXPORT_ES6`, depending on `WasmEnableES6` to produce ES6 or CommonJS modules respectively. - `WasmEnableES6` enables `WasmBuildNative` because `dotnet.js` need to be re-linked - CommonJS version is able to be loaded into global namespace and behaves as before this change. - Added new `modularize-dotnet.*.js` files which are included in `dotnet.js` creation. - it exports `createDotnetRuntime` method instead of global `Module` - `createDotnetRuntime` takes function which creates `Module`-like config `(exports) => EmscriptenModuleConfig` . - `createDotnetRuntime` returns `Promise<{MONO, INTERNAL, BINDING, Module}>` exports. - New `Module` extension `EmscriptenModuleConfig` has following new fields - `EmscriptenModuleConfig.disableDotNet6Compatibility` - when `true` and if runtime script is loaded as module, it would not polute global namespace. - `EmscriptenModuleConfig.configSrc` - location of `mono-config.json` as defined by `MonoConfig` .ts type - `EmscriptenModuleConfig.onConfigLoaded` - callback called early during runtime init, when `MonoConfig` was loaded but runtime didn't start yet. - `EmscriptenModuleConfig.onDotNetReady` - callback called when runtime is ready and all artifacts were loaded form `MonoConfig`. Or not called at all when `onRuntimeInitialized` is overriden in Blazor. - Removed legacy `--testing` argument and simplified `is_testing` logic in the the samples. - Added `browser-es6` sample app, which uses `WasmEnableES6=true` to compile `dotnet.js` as ES6 module. - Added `browser-legacy` sample, which uses `dotnet.js` CommonJS module and loads it into global namespace. - Improved `dotnet.d.ts` - Attempt to fix In-Tree `_WasmSelectRuntimeComponentsForLinking` when `WasmBuildNative`
