#microsoft visual studio lightswitch application

[sharepointsolutions-blog]

I am currently working on a LightSwitch HTML client application in which I faced an issue of validating textbox. For example, upon setting up a Boolean Yes/No field to Yes, the relevant text field must contain a value. I figured out that it can be done by using focus out event of that textbox, so I need to find out a way to implement focus out event of a textbox in LightSwitch.

I receive following errors whenever I use LightSwitch application on my system which was previously created by someone else:

Could not load file or assembly Microsoft.Data.EDM Version=5.2.0.0 Could not load file or assembly Microsoft.Data.OData Version=5.2.0.0 And any other library like abc.xyz version=1.1.0.0 etc.
