Hi team,
We are facing below list of issues with telerik test studio. We would like to know what will be the best approach to capture and run automation test cases for Silverlight web application.
Using telerik test studio we have automated our Siliverlight application but some of the test cases getting fails. Sometimes it works sometimes not.
1.	Test step to select an item form Dropdown/ComboBox fails.
2.	New version (2015.3) of telerik test studio take longer time to start execution of test cases from Visual studio. When we execute test cases from test studio, it run faster won’t take time to start execution. 
3.	Today’s captured/modified test cases works fine but the same test cases we run on next/later days than it fails at certain steps. Like element not found, not able to select an item from dropdown etc.
4.	Some of the test cases get fail when we schedule it but the same test case works fine we run it individually.
5.	We are using TFS for source code repository, Sometimes when we open automation project in visual studio than all test case files get checked out though we have not made any changes.
6.	Not able compare two different version of one test case file(if two user works on same file and one has checked in it and another one is taking latest to merge both file).
Please provide resolution of these queries. Continuously we are facing these issues.
Also let us know what are the best practice to work with telerik test studio for web app automation.
