Use different versions of referenced DLL

Question

Somehow I\'ve been lucky and never had to deal with this problem, even though I think it\'s a common one:

I\'ve got a web project, let\'s call it SomeProject

Answer 1

Putting both versions of SomeThirdParty into GAC should do what you want. Use gacutil utility or Start->Run->assembly then drag-n-drop.

Answer 2

From my answer earlier: https://stackoverflow.com/a/19576769/2367343

I ran into this yesterday for visual studio web developer using Oracle.DataAccess.dll.

My solution,

right click your project (*.csproj) and edit it.

Right underneath:

<PropertyGroup>

Place

<AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>

Then rebuild your solution. You must separate the two version dlls into two different directories in your project when including them (required).

I did

ora11 >> Oracle.DataAccess.dll (Version 11)

ora9 >> Oracle.DataAccess.dll (Version 9)

Doing this allows your IDE to use both versions of DLLs.
