C# Programming :: referencing 2 versions of same assembly


	referencing 2 versions of same assembly how can i reference two versions of the same assembly? they exist in two seperate files. since they have the same name they can't simply be referenced. (i am writing a program that updates data that was serialized with version 1 of the class/assembly and store it in the class format for version 2) thanks m * M R wrote, On 29-5-2007 13:23: > how can i reference two versions of the same assembly? they exist in two > seperate files. since they have the same name they can't simply be > referenced. > (i am writing a program that updates data that was serialized with version 1 > of the class/assembly and store it in the class format for version 2) I think the only way to do this is to load each assembly in a different AppDomain. It's not going to be easy. Can't you Update the code in Assembly 2 to understand the way objects were serialized in Assembly 1? This is how I usually do this....

Not tested, but should work: 1 In the propertie window of the reference set specific version to true; 2 For each reference in the propertie window aliases enter an identifier scecific for the version eg. WidgetsV1 and WidgetsV2 3 In codefiles where you want to referent one or both of that assemblies enter an extern alias directive with the identifier from point 2. 4 reference the class in following form: WidgetsV1::NamespaceName.ClassName This also can be done in a using directive.
