Yesterday, I shut up my Windows 7, an Windows update was pending there without any process for nearly one hour, then I shut my laptop. When I re-opened my Windows 7 and ran the PMP MVC application, this error occurred. I finished that pending windows update. That did not fix the issue.
I googled to find that should re-install .net framework 1.1/2.1, I tried but nothing good happened. This error always here. I spent 4 hrs re-installing VS 2010, but it didn't resolve the issue.
How can I fix this issue?
[Update]:
I tried this,
"C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\gacutil.exe" /i Microsoft.NET/Framework/v2.0.50727/System.EnterpriseServices.dll
"C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\gacutil.exe" /i Microsoft.NET/Framework/v2.0.50727/System.EnterpriseServices.dll
to found that gacutil.exe in v6.0A is 0kb. Then replace the file in v7.0A to v6.0A. This didn't solve the issue either.
Copy the file System.EnterpriseServices.Wrapper.dll
from
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
to
C:\WINDOWS\WinSxS\x86_System.EnterpriseServices_b03f5f7f11d50a3a_2.0.0.0_x-ww_7d5f3790\
This happened to me when I had installed windows updates (and .Net 4.5.2 update) but was putting off the restart. Restarting my computer and thus allowing the updates to finalize fixed the issue.
I fixed the
System.EnterpriseServices.Wrapper.dll
by installing .NET framework 3.5.
The Framework 3.0 caused the problem.
delete bin folder in project, then rebuilt it.
In one case, the System.EnterpriseServices.dll had been checked into version control and was read only. Simply deleting that individual dll and rebuilding fixed the issue.
run Visual Studio as Administrator works for me
For me , I just close the solution and reopen. Its solved.
I just stop IIS Express and run again my application.
