Could not load file or assembly Microsoft.Data.EDM Version=5.2.0.0

Hello everyone!
Currently I am working on a LightSwitch application created by some other person before. It was working fine on his development environment but the time when I copied that solution to my system, it returned some errors related to assembly references. I tried to remove and add those references many times but I think there must be some version problem.

Now it returns following type of errors.
Could not load file or assembly Microsoft.Data.EDM Version=5.2.0.0
Could not load file or assembly Microsoft.Data.OData Version=5.2.0.0
And any other library like abc.xyz version=1.1.0.0 etc.

I have added version 5.2.0.0. What changes do I need to make in order to run these versions of assemblies.

Any help would highly be appreciated. Thanks!

 

Hi Abbie!
First of all please verify the version of the actual referenced dll file with the version mentioned in web.config file.


For example in our case we have a reference of Microsoft.Data.EDM Version=5.2.0.0

And we have following code in our web.config.

<dependentAssembly>

<assemblyIdentity name="Microsoft.Data.Edm" publicKeyToken="31bf3856ad364e35" culture="neutral" />

<bindingRedirect oldVersion="0.0.0.0-5.6.0.0" newVersion="5.6.0.0" />

</dependentAssembly>


Try to replace <bindingRedirect oldVersion="0.0.0.0-5.6.0.0" newVersion="5.6.0.0" /> with

<bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.2.0.0" />.


I hope this will probably solve the issue. If not you may want to get help from: http://blog.itlinksolutions.com/post/2016/03/31/Could-not-load-file-or-assembly-Microsoft-Data-EDM-Version-5200.aspx
