"Telerik.OpenAccess.MySql.Data" Reference Error
The Visual Studio projects created by the Sitefinity Project Manager include an invalid reference. Opening a project in Visual Studio and building it results in the following build error:
c:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3245: Could not resolve this reference. Could not locate the assembly "Telerik.OpenAccess.MySql.Data". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.Hi Mike,
I saw the issue and yes, the following reference should be removed for now if you experience compilation issues.
<Reference Include="Telerik.OpenAccess.MySql.Data, Version=2010.2.1013.8, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>bin\Telerik.OpenAccess.MySql.Data.dll</HintPath>
</Reference>
Kind regards,

Had this problem. Did a global search for Telerik.OpenAccess.MySql.Data reference and never found any. So I removed the referenced assembly and built anyways.
Now, I've copied the DLL to the new 4.1 project and I'm getting this error, please help.

Hi Travis,
Maybe your problem is not related to Telerik.OpenAccess.MySql.Data, at least it is not mentioned in the error description. Let me know if I am missing something.
Can you send us the log files, generated around the time this exception is thrown? They are located in ~/App_Data/Sitefinity/Logs folder.
Greetings,

Hi,
Could you check if you haven't removed any dll from your bin folder? This will happen if you perform rebuild. The error says that there are missing assemblies that couldn't be loaded.
All the best,

Hello Ivan,
When I make considerable changes to my solution, I clean it then recreate the bin folder with dlls from sitefinity's "empty project" bin folder.
Otherwise I just do a build.
Hi,
The error says that there are missing assemblies that couldn't be loaded, so you are missing a dll or reference.
All the best,
