I deployed some solutions to Sharepoint Central Administration.
After this, the Central Administration can't open. this error appear when I try access the site:
Error
Could not load file or assembly
'Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The
system cannot find the file specified.
I saw at some blog this error occur because the solution isn't compatible with sharepoint foundation.
So I uninstalled all solutions from site using PowerShell's Command. But the error persist.
What I need to do to fix it?
I assume you only have SharePoint Foundation installed since you get this error, (and not SharePoint Server).
I would check the web.config of the central admin website for references to 'Microsoft.SharePoint.Publishing'. Probably the custom solutions you installed left some traces there and that's causing your problem. It's not pretty but you'll probably need to remove these references manually.

i am getting below error in SharePoint 2019 site.
Could not load file or assembly 'Microsoft.Office.Excel.WebUI, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.
i have added the assembly in GAC and did changes in web.config as well. Still same issue even after IISRESET and server reboot. Please help.
i have followed steps mentioned in below URL as well

Troubleshoot the issue, check things below:
Remove the web parts and re-insert the web parts.
Add the following entry to the assemblyBinding section of the web.config file:

I have tried multiple ways to get the production SharePoint content to my newly installed local development environment that is running on a VM Windows Server 2008 R2. After an export of the farm and a restore failed I came across this blog post and followed these instrucitons: http://richardstk.wordpress.com/2012/02/03/build-a-sharepoint-2010-development-test-environment/. To sum up, it's basically backing up the live SQL Content database as well as the Profile, Sync and Social databases, then restoring them on the dev machine and pointing SharePoint to use these new databases instead of the old ones. Then after that I deployed the custom webparts to the development server from within Visual Studio.
I've done this and it seemed to work pretty well. I can access Central Administrator as well as setting up a SharePoint Connection within Visual Studio and being able to see all the pages, lists, documents, etc. So it is definitely pointing to the new content database. I should mention I can also connect via SharePoint Designer and access all the correct content, Master Pages, lists, etc.
The problem I am having is that I am getting a "Could not load file or assembly" error when I go to the site in a browser and it takes me to /Pages/Home.aspx. The file is a custom webpart that I have deployed from within Visual Studio. When I look within the GAC I see the assembly listed but the PublicKeyToken is different from the one that is shown in the error message.
When I dig into it a little more I see that the custom user control is registered in my Master page, and when I look at the ascx file in the _controltemplates directory where it is located there is an Assembly that looks like this:
<%# Assembly Name="BlogRoll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=529e9730fe2a198d" %>
That PublicKeyToken is correct for the live site when I look in the GAC there but when I deployed it to my local GAC it created a new PblicKeyToken. Sorry if I'm rambling but I wasn't sure what was relevant and what wasn't.
I guess my question is how to handle this? It doesn't seem smart to change all the ascx files locally to match the new PublicKeyToken's that I have in the local GAC because then when I deploy these changes to live they won't find the appropriate assembly. What is the best way to handle this?
UPDATE
The code in question has a key.snk file that is being used to strongly sign it. My understanding is that this should make it so that it gets compiled with a specific PublicKeyToken each time and therefore install in the GAC with a specific PublicKeyToken. If that is true, then I believe the only reason it would have a different key token on my dev environment versus the production is that the key.snk file that has been provided is incorrect. Is that true?
You could use WSP Builder or WinGac to forcibly deploy the assembly with the correct PublicKeyToken to your local GAC.
In Microsoft Dynamics CRM 2011, I wrote one plug-in in C# for Account entity to do some operations on fields when Account record is created. In C# code I created my own custom assembly called My.Custom.Assembly.dll. Which contains some generic methods those I can use often in my plug-in. And I using this My.Custom.Assembly.dll and also added in reference in my project. Project builds successfully and plug-in registration also. The problem I faced when I was creating a Account record. Its throwing an error: "Could not load file or assembly My.Custom.Assembly.dll, Version=1.0.0.0 Culture=neutral, PublicKeyToken=def751c98b41d765 or one of its dependencies.The System cannot find the file specified." I got to know the problem is with My.Custom.Assembly.dll. Can you please help me to solve this problem..?
Your custom assembly cannot be loaded during the execution of your plugin.
Either install it in the GAC or merge it with your plugin assembly.
See my answer at Plugin with references not working on CRM 2011
A good place to start debugging this type of issue is to use Fusion Log Viewer to see the details of how .Net runtime is attempting to load the assembly. http://msdn.microsoft.com/en-us/library/e74a18c4(v=VS.100).aspx
Based on what you find in the log post more details if you need additional assitance.

I have build one employee directory webpart that gets necessary information of user from sharepoint site. i have deployed in my testing server "Windows Server 2003 and Moss2007" and it's work fine.
When i tried to deploy on my production server "Windows Server 2008 R2 with Moss2007". It give me security error.
Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed."
I have also created security policy file and added reference to web.config. Still i getting same error please help on this. i am stuck here and not able to find any way to get out of this.
Thanks in advance.
Do you install your DLL into GAC? You must either install it into GAC (the solution does it for you if you specify the assembly location as GAC) or provide a custom CAS policy and register that policy in the web.config file. We usually prefer the first way, unless a customer specifically requires a custom CAS policy. This is much easier and I really doubt the security-wise effectiveness of the custom policy approach (unless your IT department actually goes over your code and examines what it can and cannot do, haven't found a department that would know how to do that)
I created a code behind file for a custom master page in visual studio. I hooked everything up manually; safe control and custom cas policy. Everything works great!
I then wanted to put this into a sharepoint solution using WSPBuilder for better deployment. I created WSP solution, added my class file and changed the output directory to the bin folder. I then built the solution and deployed it, making sure to change the page directives on the master page to reflect the new assembly name.
Now when I go to view the sharepoint site I get an error stating Security Exception error stating
‘Exception Details: System.Security.SecurityException: That assembly does not allow partially trusted callers.’
This has me stumped as it works as a visual studio class file deployed to the bin directory of the website.
However when I put this into a sharepoint solution it breaks! I tried adding
‘[assembly: System.Security.AllowPartiallyTrustedCallers]’
to the AssemblyInfo.cs but this hasn’t helped.
Anyone else experinced this or have any advice?
EDIT: I should also mention that the code behind is trying to access a sharepoint list.
Don´t you still have to include the SafeControls entry in order for it to work, like:
<SafeControl Assembly="[FullAssembly Name]"
Namespace="[YourMasterPageNamespace]"
TypeName="*"
Safe="True" />
or in WSPBuilder config:
<add key="BuildSafeControls" value="True" />
Never seen this.. but I suspect not many people have created codebehinds to the master pages in SharePoint (Microsoft doesn't too!).
I don't know what you are trying to build but I'd probably implement it using a server control that is included on the master page.
AllowPartiallyTrustedCallers has always fixed it for my server controls.
What is the trust in your web.config file set to? Try Full.
Are you calling a third party assembly?
I ran into a situation recently that I was using a third party assembly and it did not have AllowPartiallyTrustedCallers in its code. When I tried to use the assebmly, it would fail.
Are you sure that the assembly has been deployed to bin and no to GAC by accident? If there are two assemblies the one in GAC takes precedence.
You might try checking that you are using the fully qualified five part name including the correct public key token and namespace for your assemblies.
