Upgraded 7.1 -> 7.5 - Type 'System.Decimal' could not be mapped to a PropertyDefinitionType
Further update, when I change the properties to an int the site loads and behaves correctly.
Can you clarify whether decimal should be supported? It is not a blocker - we can easily switch to store currency in cents and switch to using int, but decimal is more correct semantically for our site.
Many thanks,
Matt.

Hi Matt,
I just looked and we had an internal bug during development called "CMS says it supports both Decimal and Int64 but it does not". The problem was that the value was downconverted/upconverted in the database as a Double. Since this might lead to data loss the support for Decimal in CMS was removed. I will make sure that we update our breaking changes document to include this.
If you need to get back your values you should be able to change the type of your property to Double, since that's what it is stored as.

So has this been addressed or is it just going to be left not supporting decimal?

This has not been addressed yet but it is still in the backlog so it is something that we plan to support.

I'm assuming bigint (SQL server) which is mapped to Int.64 in ASP.NET C#, is not supported as well?
I'm getting a similar error, "Type 'System.Int64' could not be mapped to a PropertyDefinitionType".
Is this still not supported in EPiServer 8.0?

Hi Nicola,
EPiServer 8 does not support Int64. There's a list of our supported backing types in the documentation:

In case someone stumbles upon it in 2020, the Commerce (EPiServer.Business.Commerce.dll) has the Decimal implementation located in EPiServer.Commerce.SpecializedProperties.PropertyDecimal. It uses [PropertyDefinitionTypePlugIn] Attribute. Just copy over that class to your Solution, it should be automatically picked up.

I have upgraded our 7.1 site to 7.5. I think everything is in order, with nuget references, appdata, config etc.
I am getting the following error on startup. We do have a few decimal page properties, such as:
public virtual decimal RegularAmount { get; set; }
These were perviously working fine in 7.1. Has support for these been removed or does it look like I've missed a step in the upgrade?
