Management Studio: The type initializer for ‘PropertyMetadataProvider’ threw an exception

Sql Server Management Studio, gave me the following error after I rebooted my computer:
The type initializer for ‘PropertyMetadataProvider’ threw an exception

I installed the windows updates and started relating the problem to the updates.

After some research I found a interesting artice in Sql Blog about the problem that states that the DLL versions of the cumulative update 4 for SQL Server 2014 had bad DLL versions.

The temporary workaround is:
1) Close all instances of Management studio and visual studio
2) Open a administrator command prompt
3) Execute the following commands :

         (i) cd %WINDIR%\assembly\GAC_MSIL\Microsoft.SqlServer.Smo
         (ii) rmdir /Q /S

4. Run the SQL Server 2014 setup
5. Select the Maintenance option
7. Press the Repair link
8. Pass all the per-requirement steps and click Repair button
9. Once the repair is finished launch Management studio and the error should be fixed
