Execute-PowerShell Throws Exception

[jharbison]

After updating from 5.5.3 to 5.6.2, plans utilizing the "Execute-PowerShell" command throw the following exception.

   Unhandled exception: System.MissingMethodException: Method not found: 'System.Nullable`1<Inedo.ExecutionEngine.RuntimeValue> Inedo.BuildMaster.Extensibility.Operations.IOperationExecutionContext.TryGetVariableValue(Inedo.ExecutionEngine.RuntimeVariableName)'.

I rolled back to 5.5.3 and verified my plans were working again and incrementally updated versions. It looks like the problem started occurring in 5.6.0

Product: BuildMaster
Version: 5.6.2

This should be resolved in v5.6.0 of the Windows extension. Can you verify which version of that extension you have installed?

Thanks. That was the problem. After updating the Windows extension from 5.5.0 to 5.6.0 the powershell command is working again.
