Problem Description

I initialized a new React Native Windows App using C# and the react-native-windows NuGet packages in order to minimize the build time. The application builds without any issue but crashes after a couple of seconds. The exception is the following:

Exception thrown at 0x0000000000000000 in CSAppNuget.exe: 0xC0000005: Access violation executing location 

And the call stack:

Microsoft.ReactNative.dll!Microsoft::ReactNative::`anonymous namespace'::initHermesApi() Line 55 at D:\a\_work\1\s\vnext\Shared\HermesRuntimeHolder.cpp(55)

On output window I get this:

ERROR: Native images generated against multiple versions of assembly Microsoft.UI.Xaml. Exception thrown at 0x00007FF99948CF19 in CSAppNuget.exe: Microsoft C++ exception: EEMessageException at memory location 0x000000B4E82FA030.

Should I try using Chakra instead of Hermes? I also tried initializing the app without the --experimentalNuGetDependency true option and it runs normally.

Steps To Reproduce

1.npx react-native init CSAppNuget --version latest 2.cd CSAppNuget 3.npx react-native-windows-init --language cs --experimentalNuGetDependency true --version 0.73.4 --overwrite 4.yarn windows

Should I try using Chakra instead of Hermes?

As far as something to try, you can. Hermes is our default test case now though.

We have testing for CLI new projects on nugets, but those tests target an exact version (e.g. 0.73.0) so perhaps there's been a regression here. We need to try validation against the more recent version.

[jonthysell]

I have confirmed the repro for C# apps, the code crashes when trying to set up the Hermes Inspector. See if its repros with C++ apps too.

[jonthysell]

It does not repro in the C++ app with the experimental nuget, it launches and uses Hermes just fine.
