Fields

Name	Value	Description
LegacyBehavior	0	Search the application directory, and then call the Win32 LoadLibraryEx function with the LOAD_WITH_ALTERED_SEARCH_PATH flag. This value is ignored if any other value is specified. Operating systems that do not support the DefaultDllImportSearchPathsAttribute attribute use this value, and ignore other values.
AssemblyDirectory	2	When searching for assembly dependencies, include the directory that contains the assembly itself, and search that directory first. When used in Native AOT and single-file deployment models, the application's installation directory is considered the "assembly directory" and is searched.
UseDllDirectoryForDependencies	256	Search for the dependencies of a DLL in the folder where the DLL is located before searching other folders.
ApplicationDirectory	512	Include the application directory in the DLL search path.
UserDirectories	1024	Include any path that was explicitly added to the process-wide search path by using the Win32 AddDllDirectory function.
System32	2048	Include the %WinDir%\System32 directory in the DLL search path.
SafeDirectories	4096	Include the application directory, the %WinDir%\System32 directory, and user directories in the DLL search path.

Remarks

Use the DefaultDllImportSearchPathsAttribute attribute to apply a set of paths to an entire assembly or to an individual platform invoke.
