@markhobson As I know, this error is caused by the new security transparent model introduced by .NET 4.x. Please read https://docs.microsoft.com/en-us/dotnet/framework/misc/security-transparent-code-level-1. Microsoft is getting rid of old assembly attribute AllowPartiallyTrustedCallersAttribute, which is used in NPOI assembly setting.
Assembly does not allow partially trusted caller
Assuming you have access to the sources of your library.
- Give the library you are trying to call a strong name.
- Add [assembly:AllowPartiallyTrustedCallers] to the library that you are trying to call.
- Create a code group to set permissions to the library
A pretty good and detailed explanation is given here Also read the links at the bottom to get a better understanding.
There is a possibility that not your assembly is the problem but you are calling another assembly that does not allow partially trusted callers. At runtime you can use fuslogvw to find which assembly is giving you the problems. If this is the problem and you have the sources of this assembly you need to also apply the [assembly:AllowPartiallyTrustedCallers] attribute to that assembly, if you don't have the sources the only option I know of is to replace the troublesome library.
4.3在IISRemoting的solution中，升级NPOI之后

CMS.Controls.dll依赖于CMS.ISearchEngine.dll
CMS.DocumentEngine.dll
CMS.IO.dll依赖于ICSharpCode.SharpZipLib.dll
写代码来检查依赖

NPOI 2.1.3可以降级使用ICSharpCode.SharpZipLib

排查之后发现是因为xmlns的问题导致的
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">这里的xmlns和<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">里面的xmlns不能相互兼容导致的。
直接删掉configuration里面的xmlns，然后bindingRedirect就可以正常工作了
