New in the August 2017 Release of Microsoft Analysis Services Projects (VSIX Update 1.18):

*NOTE: THIS NOW REQUIRES VISUAL STUDIO 2017 UPDATE 3*

Vastly improved performance when committing model changes (DAX edits for measures, calculated columns) when tabular model contains larger metadata
Fixed a number of issues with importing data using PowerQuery in 1400-compat level models
- Import takes a long time after clicking Import and UI shows no status
- Large list of tables on Navigator view when trying to select tables to import very slow
- Query Editor poor performance working with list of 35 queries in Query editor view (issue in PBI desktop too)
- Importing multiple tables disabled toolbar and may never finish in certain situations
- Model designer appeared disabled and showed no data after import of table using PQ
- Unselecting "Create new Table" in PQ UI still resulted in a new table being created
- Folder data source not prompting for credentials
- Object reference not set exception that may occur trying to get updated credentials on structured data source
- Opening partition manager with M-expression was very slow
- Selecting Properties on table in PQ editor didn’t show the properties
Improved robustness in Power Query UI integration to catch top level exceptions and show in Output window
Fixed an issue with ChangeSource on structure datasource not persisting changes when context expression
Fixed an issue where M expression errors may cause failures to update the model without error message shown
Fixed an issue closing SSDT with error "The build must be stopped before the solution can be closed"
Fixed an issue where VS may appear to hang when setting wrong impersonation mode in 1400 compat-level model
Detail rows property will now only be serialized to JSON when it is not empty (changed from default)
Oracle OLEDB driver now available in the list for tabular Direct Query mode
Adding M-Expressions in 1400-compat tabular models now appear\refresh in the Tabular Model Explorer (TME)
Fixed an issue that caused MSOLAP provider to not show up in VS2017 when trying to import using “Other” datasource in pre-1400 compat level models
Fixed an issue where adding a translation through TME may cause issues
Fixed an issue in the Object Level Security interface that caused the tab to appear\hide incorrectly in certain cases
Fixed an issue where failure could occur attempting to open previously loaded multi-dimensional model using Connect to Database dialog
Fixed an issue that caused an error when adding custom assemblies to a multi-dimensional model

*Note: If you already have the previous version of both Reporting Services and Analysis Services extensions installed together, you may need to uninstall both before installing the new version of this extension.*

Package includes support for Tabular and Multidimensional projects. After creating a new model project by using one of the templates, you can begin model authoring by using the designer tools and wizards included in the chosen project type. Among other things, you can import existing models from a server or from Power Pivot or start a new, blank model project.

Analysis Services modeling projects integrate with source control, such as Team Foundation Server and many third-party source control plug-ins. If you have configured Visual Studio to use source control, you can use check in/check out from Solution Explorer.
