DllExportAppDomainIsolatedTask does not support ProcEnv

[pansila]

Steps to reproduce:

1. Install UnmanagedExports 1.2.7 as I found it before DLLExport when searching.
2. Install DllExport by DllExport.bat
3. Remove UnmanagedExports in the references.
4. Build the project.

• DllExport -version: 1.7.1
• Used Visual Studio 2019

@pansila I think you already answered yourself.

1. Install UnmanagedExports 1.2.7 as I found it before DLLExport when searching. 3. Remove UnmanagedExports in the references.

You need to fully remove UnmanagedExports package, then try again. Please confirm it.

@3F Thanks, after deleting the directory of UnmanagedExports in the packages of my project, the issue is gone.
