Fix is being backported for rc2: #75295

[lewing]

With that fix

A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in 'C:\Users\daroth\source\repos\WasmBrowserApp\WasmBrowserApp\bin\Debug\net7.0\browser-wasm\'.
Failed to run as a self-contained app.  - The application was run as a self-contained app because 'C:\Users\daroth\source\repos\WasmBrowserApp\WasmBrowserApp\bin\Debug\net7.0\browser-wasm\WasmBrowserApp.runtimeconfig.json' did not specify a framework.  - If this should be a framework-dependent app, specify the appropriate framework in 'C:\Users\daroth\source\repos\WasmBrowserApp\WasmBrowserApp\bin\Debug\net7.0\browser-wasm\WasmBrowserApp.runtimeconfig.json'.
