Overview
Comment:In the SQLiteFunction class, check if the database connection is open prior to attempting to call the Cancel method. Add NoFunctions connection flag to skip binding functions registered in the application domain. Fixes and adjustments to comments. Add several data-types for compatibility purposes. Fix for [fe50b8c2e8].

<p>
    <b>1.0.87.0 - June XX, 2013 <font color="red">(release scheduled)</font></b>
</p>
<ul>
    <li>Add all the necessary infrastructure to allow virtual tables to be implemented in managed code. Fix for [9a544991be].</li>
    <li>The DbType to type name translation needs to prioritize the Entity Framework type names. Fix for [47f4bac575].</li>
    <li>Add DateTimeFormatString connection string property to allow the DateTime format string used for all parsing and formatting to be overridden.</li>


    <li>When reading a DateTime value, avoid unnecessary string conversions. Fix for [4d87fbc742].</li>
    <li>Modify the index introspection code so that it does not treat PRAGMA table_info &quot;pk&quot; column values as boolean. Fix for [f2c47a01eb].</li>
    <li>Disable use of the new connection string parsing algorithm when the No_SQLiteConnectionNewParser environment variable is set. Pursuant to [bbdda6eae2].</li>
    <li>Rename the ReturnCode property of the SQLiteException class to ResultCode.&nbsp;<b>** Potentially Incompatible Change **</b></li>
</ul>
