I have developed a simple project. where i have to print some crystal report. the project runs very well in local machine, but when i up this on a web hosting server, it shows me an error when crystal report viewing.

Please any one can help me .....
I had the same error after moving to a new laptop (Windows 10). In addition to setting Copy Local to true as mentioned above, I had to install the Crystal Reports 32-bit runtime engine for .Net Framework, even though everything else is set to run in a 64-bit environment. Hope that helps.
As I said in comment your crystaldecisions.reportappserver.commlayer.dll is not copied / present on your server. So for this you have to manually copy the dll and paste into you Bin folder
To copy a DLL from visual studio project follow the steps
1.Expand your Project's References hierarchy (Project should not be in debug mod)
2.Right Click on Particular Dll (in your case crystaldecisions.reportappserver.commlayer.dll) and select Properties and set 'Copy Local' attribute to TRUE
3 Build your project. The Dll should be there in your BIN Folder.
I faced the same issue and used the following steps to solve it
1) go Right side in solution explorer
2) Click on your Project Name
3) click on Reference
4) you can see yellow symbol on some DLL
5) Right click on that DLL and go to Property
6) Find Specific Version = True replace it with Specific Version = False
and also change Copy Local = False to Copy Local = True
CR has changed the Version No of Assemblies. The Old Version is 13.0.2000.0 (this is a incompatible version problem). The New Version is 13.0.3500.0 or 13.0.4000.0 - this is for my test case of Visual Studio 2019 and .net 4.7.2 and Window Server 2019. You need to open all your projects, Remove the old dll reference and add the new references. Then build the application again.
I learnt from source:

Installation Notes
Crystal Reports for Visual Studio 2017:
https://www.tektutorialshub.com/crystal-reports/crystal-reports-download-for-visual-studio/#Service-Pack-16
TO remove: Right click on an assembly under references to remove it.
This is where the error comes from - it is exactly what the error message outputs:
error message:
Could not load file or assembly ... The located assembly's manifest
definition does not match the assembly reference ...
location error message referring to:
"C:\Visual-Studio-2019-Proj\Proj Windows Inventory\Proj Windows
Inventory\obj\x86\Debug\Press HDL Windows Inventory.exe.manifest"
And it looks like this:
-The older version of .net 3.5 and CReports version="13.0.2000.0" and VS2012:
<dependentAssembly dependencyType="install" allowDelayedBinding="true" codebase="CrystalDecisions.CrystalReports.Engine.dll" size="372736">
<assemblyIdentity name="CrystalDecisions.CrystalReports.Engine" version="13.0.2000.0" publicKeyToken="692FBEA5521E1304" language="neutral" processorArchitecture="msil" />
-The newer version of .net 4.7.2 and CReport version="13.0.4000.0" and VS2019:
<dependentAssembly dependencyType="install" allowDelayedBinding="true" codebase="CrystalDecisions.CrystalReports.Engine.dll" size="373248">
<assemblyIdentity name="CrystalDecisions.CrystalReports.Engine" version="13.0.4000.0" publicKeyToken="692FBEA5521E1304" language="neutral" processorArchitecture="msil" />
Edit Web Config for each CrystalDecisions file version make it same version of the .dll file (Right-click on it and select properties within solution explorer)
For example.
crystaldecisions.reportappserver.commlayer.dll --> 13.0.2000.0
after upgrade crystal report to CRforVS_13_0_21 edit it to ---> 13.0.3500.0
Somehow I had the wrong versions of the DLLs registered in my project.
I removed the three references to the Crystal Report dlls from my project.
I right click References, and click Add Reference
In the popup window, I click the Browse menu on the left and the Browse button
In the Directory window where your DLLs reside (perhaps your application's bin directory), select the three Crystal Reports DLLs and then click Add.
Back at the Reference Manager window, click in the first column to the left of the three Crystal dlls, and then click OK
At this point your Crystal Reports should work again.
I faced the same issue when move to new laptop and used the following steps to solve it
Close the project
Install SAP Crystal Reports 13.0 runtime (32-bit) enter image description here
Delete the project .suo file
Open the Project and first built the project
Now after running the project issue is resolved.
In the first plate you have to check that:
1) You install a appropriate version of Crystal Reports SDK =>
http://downloads.i-theses.com/index.php?option=com_downloads&task=downloads&groupid=9&id=101 (for example)
2) Add reference to dll =>
crystaldecisions.reportappserver.commlayer.dll
For me it was "Prefer 32bit": clearing the checkbox allowed CLR to load Crystal Reports 64bit runtime (the only one installed).
If you already have the DLL copied to your project and the Copy Local flag is in true, the solution should be just rebuild the project. That will copy the DLL to the bin folder.
For visual studio 2019
change the code in aspx.cs page

If you have the to your project and the Copy Local flag is in true, the solution should be just the project. That copy the DLL to the bin folder.
I am getting the following error while loading the site.master page of my website
Error:
Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. C:\TravelRequest_old\App_Themes\Aqua\MVCxPivotGrid.skin
I have uploaded the new dll file of syetem.web.mvc version 3 in
C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3 and also added the reference from solution explorer.Then I am getting the following error
Error :
Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key.
Have you declared this assembly in your Web.Config :
<system.web>
<compilation targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</assemblies>
</compilation>
</system.web>
I have a legacy WebSite project (as opposed to a Web Application project). It was using .net 3.5 but I am updating it to 4.0.
Due to the compilation error ...
Compiler Error Message: CS1705: Assembly 'System.Web.Mvc, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35' uses 'System.Web.WebPages,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has
a higher version than referenced assembly 'System.Web.WebPages,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
... I added a reference to the newer version of System.Web.WebPages. This added the following line to the web.config file:
<add assembly="System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
However, when I try to build the website I get this error:
The type 'System.Web.WebPages.WebPage' exists in both
c:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Web.WebPages\v4.0_2.0.0.0__31bf3856ad364e35\System.Web.WebPages.dll'
and 'c:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Web.WebPages\v4.0_1.0.0.0__31bf3856ad364e35\System.Web.WebPages.dll'
I cannot seem to find a reference anywhere in the project to the v4.0 1 version of WebPages. I assume this means that some other assembly is probably referring to it but I'm not sure where to go from here.
Any idea how to track down what is referring to the assembly and either remove the reference or update the calling the assembly?
My Website is working fine locally but got problem in making live.
Parser Error Message: Unknown server tag 'asp:ScriptManager'.
I googled this problem and find solution as...

I have uploaded ajaxtoolkit in Bin folder???? Please help me out...
Most likely you haven't configure the right .net version. Check with your webhosting company or control panel to see what .net version your site is using. You can also try smarterasp.net, they let you set your own version via their control panel too.
I am migrating web apps to new hosting servers, but when I try to access them to test on the new server, I get all these assemblies not found errors like:

Does anyone know where you find these to install or how to migrate them over?
That's part of the ASP.Net AJAX kit.
You will have to either install the ASP.AJAX kit on the server, or include the assemblies in your project. This question and this question say you how you can include the libraries as DLL or JS.
