JOSE JAVIER COLUMBIE
Hello XAFers,
We are back with another issue of XAFers weekly. We had to skip a week for some personals and work related issues but I was craving to send this issue out as there are a lot of great links.
The second XAFers Community Standup was a lot of fun and even if we had some audio issues we discussed Blazor, Xenial, XAF and XPO. Thanks to everyone who showed up and in the same note our Facebook Group has now more than 400 members, so Whoooo! We together are stronger and I personally I am thrilled to be part of the XAF community and to share with everyone the wonders of XAF development.
Before I go, if anyone is an audio expert and could help us with the XAFers Community Standup video please send me an email.
Until next time, XAF out!

XAFers Community Standup - May 14th 2020 - Blazor
Second community standup completed. We talked a lot about Blazor and I personally had a lot of fun. (Hope you guys did too) Unfortunately we had some audio issues and the recording has an echo that I could not get rid off and I tried with a lot of audio tools. It would be amazing if anyone in the community is an expert in the area and could help us improve the video.
And remember to join us the second Thursday of every month for our community standup covering everything that is going on with XAF, XPO, Blazor and more. There is no agenda, no formality, no dress code required, let's just talk about what we love and share our experiences.

XPO
XPO may throw OverflowException if String or Byte Array value length (size) is greater than the maximum allowed database column size
Not all databases throw an exception if a parameter size exceeds the DB column size. Some databases silently truncate the value, and users lose their data. But not anymore, in v20.1.4 XPO may throw an OverflowException for this scenario.

XPO may throw InvalidCastException or SqlExecutionErrorException if parameter types (for update/read queries) do not match database column types
XPO keeps getting better, another improvement where if parameter types (for update/read queries) do not match database column types we will know it right away. One of the reasons for this is to support for Microsoft SQL Server's Always Encrypted functionality that requires type and size information for DbParameter. Great work XPO team!

XPO - Important Changes to Default Query Parameter Validation (v20.1)
One thing I love about XPO is that if the default behavior does not fit your needs you can always change it. This is one of those cases. We presented the two links above, and here you will see how to revert back to previous behavior.

Net Core
Core - Model Editor-related context menu items may not be shown in the Solution Explorer if a solution with multiple projects contains non-XAF-based projects at the top inside the SLN file
If you had this issue before ... spoiler alert: Edit the SLN file in a text editor and place an XAF-based project at the top. That should take care of it.
