Nuget package version parse failed

Hi,

I am trying to push a nuget package to proget and I get the following error:

An error occurred processing a PUT request to http://10.255.11.19:81/nuget/Default/: Invalid version number.

System.FormatException: Invalid version number.

The version that I try to push is:
0.1.0-20180221T113336.28ecd3c.0
Which is a valid semantic versioned version, at least to my understanding.

The Proget version I use is: 5.0.8 (Build 5)

Am I doing something wrong, or do I hit a bug in Proget?

Cheers,
André

Product: BuildMaster
Version: 6.0.0

Hello Andre,

The version number you posted is indeed a valid SemVer2 version number.

If you go to the Manage Feed page for the NuGet feed, is there an orange button near the top of the page that says Migrate? If that button is present, the feed is not marked as supporting SemVer2.
