I am still trying to solve the issue below and wondering if anyone on the
list is having similar issues.  There are no errors when building the

in my project:

After additional research it appears that WebUnmanagedApi.dll can?t be

target is x64 and target framework is .NET Framework 4.8. MapGuide Server
