RegAsm : error RA0000 : Could not load file or assembly or one of its dependencies. The system cannot find the file specified

Question

I am new to SharePoint. I am trying to add the Microsoft.SharePoint.dll to GAC. For that one I have used below code

Code :

 `c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319> Regasm.exe "C:\Microsoft.SharePoint.dll"`

When I press entry key, then I am getting the below error:-

RegAsm : error RA0000 : Could not load file or assembly 'Microsoft.SharePoint.Search.Native, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependenceies. The system cannot find the file specified.

Please can any one help to get out of this.

Answer 1

For that you need to use Gacutil instead of Regasm. So,

gacutil /i Microsoft.SharePoint.dll

Difference between regasm and gacutil:

Regasm: The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class. The class is registered only once, when the assembly is installed. Instances of classes within the assembly cannot be created from COM until they are actually registered. Source

Gacutil: The Global Assembly Cache tool allows you to view and manipulate the contents of the global assembly cache and download cache. Source
