Bug with Business Pack trial version + .NET 8

🌎 Discussion in English

I created a DotVVM web app in .NET 8 and I installed the trial version of DotVVM.Business.Pack (4.3.2-trial).

I followed the sample # 1 given in the documentation to add a bp:GridView to my page but I get this error then the page displays :

System.TypeLoadExceptionMethod ‘get_RowInsertOptions’ in type ‘DotVVM.BusinessPack.Controls.BusinessPackDataSet`1’ from assembly ‘DotVVM.BusinessPack.Core, Version=4.3.2.0, Culture=neutral, PublicKeyToken=77e8efd43b7ae75f’ does not have an implementation.

I downgraded DotVVM.AspNetCore from 5.0.0 to 4.3.9 and now it works fine.

Apologies for the delay in response.
The issue is caused because of DotVVM 4.3.x is compatible with Business Pack 4.3.x and DotVVM 5.0.x requires Business Pack 5.0.x. The major and minor versions must always match. See dotvvm.com/docs/4.0/pages/upgrading-from-older-versions/… for more info.

Thank you for your feedback, it’s very clear now.
