I am making a windows phone 8 application, where i use LongListSelector and DatePicker.
the LongListSelector is from windows.controls
the DatePicker is from Windows.phone.Controls.toolkit (Date Picker is not-available in Windows.Controls).

** As soon as i Drag and drop DatePicker in my design it is adding Windows.phone.Controls.toolkit.dll to references and in XAML file.
and now while building the file its saying Error 1 The type 'Microsoft.Phone.Controls.LongListSelector' exists in both 'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\WindowsPhone\v8.0\Microsoft.Phone.dll' and 'C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Toolkit\Aug11\Bin\microsoft.phone.controls.toolkit.dll'
"
** I don't need Windows.phone.toolkit to work with my LongListSelector (as it LLS is from Windows.phone)

i want to use the controls in windows.controls.. how can i achieve this.

How are you referencing LongListSelector in XAML...
share sample code

@naz_Firdouse i am not referencing LLS .. because it is inherited from Windows.Controls.

You have to either remove one of the references, or resolve the ambiguity.

yes .. if i remove the reference LLS it works perfect .. But i cant use Date-picker ! beacuse its not listed in Windows.controls

1 solution

Working method
Delete the existing windows.phone.toolkit in references..
Right click on references.. Select Manage NuGet Packages
Go online and search for windows phone toolkit.. and install it,
then add
C#
xmlns:toolKit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
in your xaml file on the top.

then type
C#
<toolKit:you will get it 



Dont Follow this method
** Don't search for your control in toolbox and drop in UI .. it will cause same error , it will generate a .dll under references
