Referencia a dos versiones del mismo assembly

Eso mismo, explicado:

Crack (maybe dangerous ) you Visual Studio Project file with this :


<Reference Include="MyFirst, Version=2.0.0.0, Culture=neutral, PublicKeyToken=1c3ef21ab2e2f12e, processorArchitecture=MSIL">
<HintPath>..\Libs\2\MyFirst.dll</HintPath>
<Private>False</Private>
<Aliases>version2</Aliases>
</Reference>

<Reference Include="MyFirst, Version=3.0.0.0, Culture=neutral, PublicKeyToken=1c3ef21b2e2f12e, processorArchitecture=MSIL">
<HintPath>..\Libs\3\MyFirst.dll</HintPath>
<Private>False</Private>
<Aliases>version3</Aliases>
</Reference>


Insert this code in "using section"

extern alias version2;
extern alias version3;


Using versions assemblies

var v2 = new version2::Dto.MyDto();
var v3 = new version3::Dto.MyDto();
