[Nant-users] Invalid element . Unknown task or datatype.

[Andy Eunson]

This appears to be a 1.1 related problem. I had a very similar issue with the solution task in nant .85 using the dist assemblies on a machine that only has NET1.1. The solution there was to use the 85RC1 dist to build the 85RC1 source (you can’t build 85 with 84). Once I did that solution magically starts to work.   Nonetheless this is what I’m seeing when using 85RC1 built locally with NET1.1 and NantContrib Dist assemblies.     [loadtasks] Failure scanning "C:\Program Files\nant\bin\NAnt.Contrib.Tasks.dll" for extensions. One or more of the types in the assembly unable to load. Buildfile: file:///D:/Data Files/Code/Solutions/SC.MasterBuild/Test/Test.build Target(s) specified: Get_Source     Get_Source:        [echo] Getting Phoenix Source tree...   BUILD FAILED   D:\Data Files\Code\Solutions\SC.MasterBuild\Test\Test.build(8,4): Invalid element <vssget>. Unknown task or datatype.     I tried to build NantContrib using 1.1 and get the following     [loadtasks] Failure scanning "C:\Program Files\nant\bin\NAnt.Contrib.Tasks.dll" for extensions. One or more of the types in the assembly unable to load.

What am I missing?
