Unexpected error has occurred during the library compilation process

I created the RE framework with Windows-legacy C#, then changed the target framework to Windows, so while opening or testing the audio framework, I got the below error.

Hi @Pujari_Manjunatha

Please recreate the project in windows instead of changing it to windows

Hello @Pujari_Manjunatha

How you modified the compatibility from legacy to windows? Just updated in the project.json file?

You can try modifying the Target framework in project.json to Windows.
Note: Sometimes this can cause issue if the package you added doesnt support the framework.
Thanks

@Pujari_Manjunatha
by selecting csharp on windows legacy configuration is not working as I have seen, so if you have any previously created Project the Same configuration which you want duplicate it and modify it how you want.
