Error while connecting to Database Server from SQL Server Management Studio

问题

Recently, while trying to connect to any SQL Server Database from SQL Server Management Studio, I am getting an error - Service 'Microsoft.SqlServer.Management.IRegistrationService' not found (Microsoft.SqlServer.Management.SDK.SqlStudio)

I tried updating to the latest version of SQL Server Management Studio but there is no change.

The full error stack is as below:

===================================

Service 'Microsoft.SqlServer.Management.IRegistrationService' not found (Microsoft.SqlServer.Management.SDK.SqlStudio)

   at Microsoft.SqlServer.Management.UI.VSIntegration.ObjectExplorer.ExplorerHierarchyNode.BuildChildren(WaitHandle quitEvent)

Any idea why this error is happening?

回答1:

What helped in my case... (version 17.9.1)

I have checked file:

C:\Users\<user>\AppData\Roaming\Microsoft\AppEnv\14.0\ActivityLog.xml

In thre I have found the information that directory:

C:\Users\<user>\Documents\SQL Server Management Studio

Has not been found. I have created it manually and... SSMS started working.

Yeah I know... It sounds crazy.

@Marek Malczewski is right, thank you sir!

I too looked at the log files and fixed it the same way, here is a screenshot for your confirmation.

Install .NET 4.8. I've had exactly the same issue and it worked for me.
