Entity Framework 4 Solution

Most of the answers here were EF6-specific. Here's one for those of you still using EF4.

This method replaces the @p__linq__0/etc. parameters with their actual values, so you can just copy and paste the output into SSMS and run it or debug it.

    /// 

    /// Temporary debug function that spits out the actual SQL query LINQ is generating (with parameters)
    /// 
    /// IQueryable object
    private string Debug_GetSQLFromIQueryable(IQueryable q)
    {
        System.Data.Objects.ObjectQuery oq = (System.Data.Objects.ObjectQuery)q;
        var result = oq.ToTraceString();
        List paramNames = new List();
        List paramVals = new List();
        foreach (var parameter in oq.Parameters)
        {
            paramNames.Add(parameter.Name);
            paramVals.Add(parameter.Value == null ? "NULL" : ("'" + parameter.Value.ToString() + "'"));
        }
        //replace params in reverse order, otherwise @p__linq__1 incorrectly replaces @p__linq__10 for instance
        for (var i = paramNames.Count - 1; i >= 0; i--)
        {
            result = result.Replace("@" + paramNames[i], paramVals[i]);
        }
        return result;
    }
