WPF呼叫Bartender 檔案出現System.AccessViolationException

1.檢查C:\Windows\assembly裡面有沒有多餘的Barteder版本
2.gacutil /u xxxxxxxx，把沒必要的刪除
//3.sfc /scannow修復mscorlib.dll
4.移除舊版本Bartender
5.安裝新版本Bartender UltraLite
6.移除新版本 Bartender UltraLite
7.安裝舊版本Bartender
6. BarTenderTask.Result.Close(SaveOptions.DoNotSaveChanges);

Clean GAC, open windows explorer and navigate to C:\Windows\Assembly - it should show a 'gac style' file view, order the files by Public Key Token, then find all 109ff779a1b4cbc7 tokens (those are bartender related). Within that set of them you'll see some which are 10.1.. version and some which are 10.0.

PS：問原廠，原廠說：誰叫你要裝兩套不同版本的
