Please refer here for more details, usually when there is a mismatch for DLLs version this error occured.

Remove the wrong version of the DLL’s and add the correct version of the DLL’s

We all D365 Developers came across this annoying error often. Today, we will try to understand this one and quickly resolve it if it appears next time.
When connecting to Dynamic CRM we are required a couple of
DLL’s which are
Now these DLL’s must be in one common version only either 8.0.0.0 or 9.0.0.0. If any one of these DLLs is not synced version-wise, then during runtime we have an error.
We can check the version of DLL’s from a property window
in Visual Studio.
Remove the wrong version of the DLL’s and add the correct version of the DLL’s
Now the NuGet way, verify if you have the same
version installed.
Important Note: If you see the version of the NuGet same
and still, run into the problem, then Uninstall the NuGet and Clean and Re-Build
the solution or try verifying individual DLL’s version as explained above.

Now we can use a single lookup field to refer multiple entities for searching (including a custom entity)
A lookup value submitted will
be matched to a record in all the related entities.
Note: For now, to achieve this it is possible only via SDK or Web APIs. Interactive user interface support will be coming in a future release.
Example:
Let's say you are hosting
media for users in a library. You have many different MediaObjects, like
“Books”, “Audio”, and “Video”. Creating a multi-table lookup called “new_Media”
that has 1:M relationships to “new_Books”, “new_Audio”, and “new_Video” will
result in a “new_Media” lookup table that provides quick identifications of
records stored in specific tables.
Shown below
is an HTTP post to CREATE Multiple lookup attribute.
It will create three relationships as depicted below
image.

Finally, we can see all entities in lookup
References
Using the lookup, we can search records by typing in the search keywords to filter the list.
This search is performed on all fields that are listed
in the Find columns in the Quick Find View of the entity.
Below are the steps in Power Apps or UCI Settings.
1] Navigate to the respective entity and click on views and edit Quick Find view for that entity.
Here is the same we can achieve in Classic mode as
well.
1] Navigate to the respective entity and click on views and edit Quick Find view for that entity.
