I am working on Visual Studio 19 Pro and have been unable to open any of my Tabular model projects. I have checked that extensions are installed have rolled back the versions and uninstalled/reinstalled and I continue to get the following:
Error Cannot build obj\Development\Model.asdatabase. Reason: Method not found: 'Microsoft.AnalysisServices.Database Microsoft.AnalysisServices.JsonSerializer.DeserializeDatabase(System.String, Microsoft.AnalysisServices.Tabular.DeserializeOptions, Microsoft.AnalysisServices.CompatibilityMode)'.
And
Method not found: 'Microsoft.AnalysisServices.Tabular.Model
Microsoft.AnalysisServices.Database.get_Model()'
I am on VS19 Version 16.8.4
Microsoft Analysis Services Project V 2.9.14
I am able to open SSIS projects and SSRS project with no issue.
Same issue here. Visual Studio 2019 version 16.8.4 Opened tabular model 2 days ago, everything was fine. Now I'm getting ![60663-image.png][1] [1]: /answers/storage/temp/60663-image.png

I am getting this exact same problem. My version of Analysis Services Projects is 2.9.15 with the same 16.8.4 version of VS (Community).

Also getting the same error message:

Visual Studio 2019 version 16.8.4 and Analysis Services Projects version 2.9.15.
Yesterday I closed the project, I try to open it today... got the error.

I had the same issue. My notebook has a Windows 10 Home Single Language with Visual Studio 2019 version 16.8.4.
I downloaded the community version and got the message:
Method not found: 'Microsoft.AnalysisServices.Tabular.Model Microsoft.AnalysisServices.Database.get_Model()'
Only uninstalling the SSIS 3.12 wasn't enough. I had to uninstall the Visual Studio 2019 entirely and reinstall it. After thar I installed the SSIS 3.11.1 and the problem was solved.
OK guys,
The error seems to come from the SQL Server Integration Services Projects extension version 3.12 released on January 25. I uninstalled it and I was able to open the tabular project and build it.
I reverted back to version 3.11.1 from December 28 and everything is fine now.

Confirmed, thanks Adam!
Uninstalled SSIS 3.12 and the tabular model now loads. Installed SSIS 3.11 and it still works. SSIS Projects 3.12 seems to be the cause.
I updated from 2.9.14 SSAS to 2.9.15 and then reverted back to SSIS 3.11 now I'm able to see my models.
Thank you Adam

Hi all,
Glad to see there's a fix to this. I can't seem to download version 3.11.1 from marketplace - blob not found.
Is there any other place where I can try and download this file?
Thanks
Well I got caught in this tap and the old version of SSIS 3.11 doesn't seem to be available via the links supplied. Where might I find this older version. Or maybe there is a different fix now?
Try getting the latest version https://marketplace.visualstudio.com/items?itemName=SSIS.SqlServerIntegrationServicesProjects
It should work.
I tried it and getting the same error: Method not found: 'Microsoft.AnalysisServices.Tabular.Model Microsoft.AnalysisServices.Database.get_Model()
Ok I uninstalled and re-installed SSDT then installed SSAS Projects then updated updated that to SSAS Projects 2.9.18. Then I reinstalled SSIS Projects 3.15. This missing piece was that I hadn't updated SSAS.
