问题
I've got a database project as part of my solution in Visual Studio 2013. Been working perfectly for the last 3 weeks and now suddenly today it won't build and so I cannot publish any changes. I'm getting an MSBuild error:
"C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\SSDT\Microsoft.Data.Tools.Schema.SqlTasks.targets(513,5): Error: MSB4018: The "SqlBuildTask" task failed unexpectedly. System.MethodAccessException: Attempt by method 'Microsoft.Data.Tools.Schema.Sql.Build.SqlTaskHost.OnCreateCustomSchemaData(System.String, System.Collections.Generic.Dictionary`2)' to access method 'Microsoft.Data.Tools.Components.Diagnostics.SqlTracer.ShouldTrace(System.Diagnostics.TraceEventType)' failed."
Anyone got any ideas? All I did this morning was pull down the latest changes from source control. I can't see how that would mess up the actual MSBuild process, and the guy who checked in last doesn't have any issues at all.

You need to install the last version of SQL Server Data Tools:
http://msdn.microsoft.com/en-US/data/hh297027
Make sure to restart VS and then build the solution again. This solves the problem!
回答2:
In Visual Studio 2013 -> Tools -> Extensions and Updates... -> Updates -> Product Updates -> Microsoft SQL Server Update for database to 12.0.50318.0
I was upgrading from 12.0.41012.0 and this resolved my issue. This relates to the answer to install the latest SQL Server Data Tools.
回答3:
I am using Visual Studio Community 2013.
I had same error:
You can fix it by updating the SQL Server Tools:
Tools --> Extensions and Updates
Then under Product Updates you will see an option to update SQL Server Update.
Click on Update, after it has installed restart Visual Studio.

Try:
- Install the latest DacFx from http://www.microsoft.com/en-us/download/details.aspx?id=43370
- Reinstall the latest SSDT from http://go.microsoft.com/fwlink/?LinkID=393521

I had the same issue. I tried to repair Visual Studio 2013, update 4, SSDT, the DAC tools, etc., but it didn't work any better.
However I noticed the Microsoft.Data.Tools.Schema.SqlTasks.targets file present in C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\SSDT was dated from 2013 (In fact it corresponded to the old SSDT). So what I did is just copy the new one (which I suprisingly found in C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\SSDT ...) over to this v12.0\SSDT folder, restarted Visual Studio 2013 and now it works. For information, that new SSDT targets file is dated from 2014/10/26 and its size is 75437 bytes.

It turns out the issue was with Visual Studio Update 3. I uninstalled and reinstalled VS 2013 to Update 2 only and reinstalled Data Tools and it works perfectly now.
回答8:
I already had the newest Version of SQL Data Tools installed, but after installing VS2015 RC it stopped to work. After run a repair on SSDT it compiles again with success.
回答9:
I had Visual Studio 2013 Update 5 installed and was having this issue. I followed these steps from above and that fixed the issue for me -->
In Visual Studio 2013 -> Tools -> Extensions and Updates... -> Updates -> Product Updates -> Microsoft SQL Server Update for database to 12.0.50730.0
回答10:
I had the same issue and just restart the Visual Studio and it works for me.
回答11:
If it helps anybody, I installed VS2014 CTP 3, and I can build from it. Interestingly after a successfull build in vs2014, the next time you build in VS2013 it works. But subsequent builds in VS2013 dont work, until you rebuild in VS2014.
回答12:
I was able to fix the issue by repairing Microsoft SQL Server Data Tools and re-starting Visual Studio 2013. Control Panel > Right Click: "Microsoft SQL Server Data Tools" > Click: "Repair" > Re-Start Visual Studio
回答13:
I had the same issue. Running disk check and then rebooting fixed it.
回答14:
I got the same error and fix it by re-install Visual Studio 2015
