An old project has a bad path for this reference, all I have is the name msdatasrc.
There are a ton of sites offering free downloads of the .dll, but they all look shady.
Where is the msdatasrc.dll file typically located?
Where can it be retrieved from if it is not present on a device?
The assembly was located for me at
C:\Windows\assembly\GAC\MSDATASRC\7.0.3300.0__b03f5f7f11d50a3a\msdatasrc.dll
The online kb328912 download is unfortunately no longer available.
It can be located in VS2017 installations at the following path
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\PublicAssemblies
