Summary: Compilation error - References for scripts
Initial Comment:
if you call a script block twice when that block has a
reference to another dll - the second times its called
it will fail with conmpilation problem
i.e.
Build Error: NAnt.Core.BuildException
Compilation failed: error CS1703: An assembly with the
same identity 'System.Data, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' has
already been imported. Try removing one of the
duplicate references. //-------------------------------
-----------------------------------------------
Having checked the source code briefly it appears this
is as there are two checks to referenced assemblies -
first check the appdomain for loaded assmeblies adding
each as a reference, then check the references element
from the task definition - if you follow this the
first time it compiles fine, then runs (and so loads
the referenced assembly) then the second time will add
it from loaded assemblies then again from the
references tag and so the compiler thinks its got the
reference twice and falls over.
cheers
