问题
The ASP.NET Core 2.2 project references Microsoft.EntityFrameworkCore.Sqlite (2.2.3) as a PackageReference.
Debugging the app in IIS Express works fine, because of the elevated user process.
Problem: Debugging the app in IIS throws an error
Unable to load DLL 'e_sqlite3' or one of its dependencies: Access is denied
How can I debug the app in IIS without laborious publishing steps?
My analysis so far: while e_sqlite3.dll is found and loaded successfully in the folder %userprofile%\.nuget\packages\sqlitepclraw.lib.e_sqlite3.v110_xp\1.1.12\runtimes\win-x64\native\e_sqlite3.dll it has only Read but no Read & Execute permission set.
The missing Execute permissions seems to be the culprit.
It works if I give Users group or ApplicationPoolIdentity also Read & Execute.
Why is the global NuGet packages folder missing Read & Execute? Is this only a problem of the unmanaged code dll's?
