Exception: An item with the same key has already been added #218
Description
I have the following two .NET Core SDK Previews installed on Windows (amongst others):
Display Name - Version - Arch - Uninstall Command
Microsoft .NET Core 1.0.0 - SDK Preview 2 (x64) - 1.0.0 - X64 - "C:\ProgramData\Package Cache\{18567b0b-ce9e-4c44-92a3-c98aba5336f6}\dotnet-dev-win-x64.1.0.0-preview2-003121.exe" /uninstall /quiet
Microsoft .NET Core 1.0.0 RC2 - SDK Preview 1 (x64) - 1.0.0 - X64 - "C:\ProgramData\Package Cache\{2adee9e7-1f53-47dc-8e30-49ff0dec528e}\dotnet-dev-win-x64.1.0.0-preview1-002702.exe" /uninstall /quiet
For both of them version 1.0.0 is extracted in RegistryQuery.GetBundleVersion leading to two different bundles with the same key 1.0.0 (x64):
This leads to an exception in
VisualStudioSafeVersionsExtractor.GetReasonRequiredStrings where now the two different bundles with the same key 1.0.0 (x64) are tried to be collected into a dictionary in the return statement:Full exception stack trace:
Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
