I am getting an error:

private async Task<List<WorkspaceEntity>> GetWorkspaces(String key) {
            var provider = new EntityManagerProvider<ShellEntityManager>();
            var uow = new UnitOfWork<WorkspaceEntity>(provider);
            var query = await uow.Entities.FindAsync(a=> a.ToolbarKey == key);
            return new List<WorkspaceEntity>(query);
        }

If I hard code a value for the "key" then it works fine. (It's just a simple string.)

This is the error that the BOS writes to the log:

Error System.ArgumentException: Argument types do not match at System.Linq.Expressions.Expression.Constant(Object value, Type type) at ....

This makes no sense to me. This project is using 7.1.0

I think it has to do with versioning as I am now getting this same error regularly in other parts of the app with no changes made.

Greg, if you've verified that your client and server are both using the same DevForce and Cocktail versions yet you're still seeing the error, please let us know.
