Class does not exist error

[TucsonDave]

I have been experimenting with creating a custom step type.  That step type calls methods in a .Net assembly.  I have been adding, renaming, and deleting a lot.  Now I get the error below when trying to use a Pass/Fail Test step type.the above error.  At this point I have deleted all my custom step types, but the error remains. 

Message : Module for Step 'Pass/Fail Test' not Loadable. Class '' does not exist in assembly 'Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

File : C:\Projects\TestStand\CheckUpdate\MySequenceFile.seq

Location : Seq["MainSequence"].Main["Pass/Fail Test"].TS.SData

'Tests' is my .Net assembly.  Note that I have deleted all custom step types (from MyTypes.ini) that reference that assembly.  What is still referencing my assembly?

When you place a step in a sequence file it copies the StepType to the sequence file as well.  Check the sequence file types and see if you have an instance in there.

Try searching for the module name in that sequence file using the TestStand "Find" feature. Perhaps you are still using the step type or have a module specified with that assembly.
