Why do you use custom version type?

[dtretyakov]

Hi, in FCL exists Version class: http://msdn.microsoft.com/en-us/library/system.version.aspx
Could you explain why do use use custom MigrationVersion type?

I agree that the FCL Version class looks like a good substitute. Perhaps @g0t4 was avoiding using a sealed class, but he probably just didn't know about the Version class.

Is there something that MigrationVersion doesn't do that you need it to?

I've made some changes in the following pull request: #5

And while looking through project I found that exists MigrationVersion class with a custom BSON serializer. After replacing of it by Version class nothing has changes, so It was interesting for me for a which purposes it was used.

May be after review of this changes you can publish a new version in the nuget?

Can we split these out into separate commits, changing Version isn't a
necessity at this point and requires further thinking/testing and I don't
see any value out of the conversion at this point

Our concern: MigrationVersion provides ability to use up to 3 version numbers, but we're using all of 4 numbers, which available in the Version class.

I'll split pull request in two parts. If you worry about backward compatibility then both of CollectionMigration and Migration classes accept version numbers as a string:

• https://github.com/phoenixwebgroup/DotNetMongoMigrations/pull/5/files#diff-c2f1554b37a76748541d6e38d1df1ac2R17
• https://github.com/phoenixwebgroup/DotNetMongoMigrations/pull/5/files#diff-f2feb3d51eca95803933f95f13445959R12

So you can look at the following:

• Upgrade to mongodb c# driver v1.9: Code cleanup for mongodb c# driver v1.9 #5
• Replaced MigrationVersion by Version: Replaced MongoVersion by System.Version class #6

[g0t4]

Awesome, that seems reasonable to me for 4 numbers

And FWIW I think this library's approach to migrations was a good starting
point, but it was based too much on the process of doing SQL migrations and
too coupled to .net (for no real reason)... going forward I will be working
on something that leverages mongo shell scripts in an organized fashion, no
reason to couple to the c# driver long term

Great, we're looking forward to look at the new migration toolkit.

[g0t4]

Hey I'm just curious, what do you use 4 numbers for that can't be accomplished with 3?

[dtretyakov]

We're using migration version associated with a complete product version.
