Problem with: Access to the path '$(sourceFolder)\Foundation\Articles\serialization' is denied

Server Error in '/' Application.
Access to the path '$(sourceFolder)\Foundation\Articles\serialization' is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '$(sourceFolder)\Foundation\Articles\serialization' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Iv tried suggestions taken from the following:
Problems with error: "Access to the path is denied."
1) Open Internet Information Systems (IIS) Manager
2) Expand the site you want to modify (hit the plus next to the name)
3) Right-click the directory where you would like to be able to write files and select Edit Permissions
4) Click on the Security tab
5) Click on Edit... under the group and users list
6) Select IIS_IUSRS from the "Groups or user names" list and add make sure the Allow checkbox is marked for Write.
ASP.NET is not authorized to access the requested resource when accessing temp folder
a really simple fix to solve my issue, in IIS I had to right click on Application Pools and set .NET Framework V4 to Integrated rather than classic/.
Another solution was to set the specific folder that was being accessed to read/write to the users that required it, this can be done by unique users or within an organization, a group of users
(https://stackoverflow.com/a/47503132/19587900)
(1) I have gone to wwwroot folder. Right-click and security tab. Provided IISUSER to set read and write permission to the wwwroot folder.
(2) Changed the application pool to the separate pool and set identity to Application pool Identity.
Iv tried other things but so far no success

Looks like you're trying to create a folder that starts with "$(sourceFolder)", that's not going to work well. Are you missing a variable definition like:
<sc.variable name="sourceFolder" set:value="c:\whatever" />

I'm using StructureMap as IoC container and StructureMap.AutoFactory, which requires Castle.Core. I'm using ILMerge to merge all assemblies into a single on. I'm using the following arguments to execute ILMerge:
/target:library
/out:"$outPath"
/log:"$logFile"
/keyfile:"${keyFile}"
/copyattrs
/wildcards
/targetplatform:"v4,${Env:ProgramFiles(x86)}\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2"
and the following assemblies (left out my dlls):
"${targetDir}StructureMap.dll"
"${targetDir}StructureMap.AutoFactory.dll"
"${targetDir}Castle.Core.dll"
I'm really out of ideas and it would be great if someone finds the time to help me. Thanks in advance!

As per this article the Sandboxed environment in which plugins run prohibits the use of Reflection to access internal members. I'm not familiar with dynamics proxying per se, but it looks like creating types on the fly and potentially using reflection in the process may not be possible in the sandbox.
If you have an on-prem dev environment you could register the plugin outside the sandbox and see what happens.

Azure database with Ninject

Have created a web application with Ninject and .Net 4 (have tested both 4.0 and 4.5) intended for Azure. The application has been tested ok on Azure before adding database support to it. Locally it runs ok with database support on SQL Express. But when altering the connect string to the Azure one and deployes it, I get the following error message.
I do NOT have a parameterless constructor in the controller, as I understand that Ninject needs one which is parameterized to work.
Azure administrative console indicates successfull connections to database.
Can anyone give me a hint for what might be wrong? I have to admit that I am new to both Azure and Ninject, this is my training project :-)

Thanks, Jakub.
Your link helped me. It turnes out that the initialization of the database is different with Azure SQL Server and SQL Express.
I altered Database.SetInitializer(new DropCreateDatabaseIfModelChanges<DataContext>());
to Database.SetInitializer(new DropCreateDatabaseAlways<DataContext>());
and then redeployed. Then it worked in Azure as well. Then I moved back to the previous one and redeployed once more. The issue seems to be the table "_MigrationHistory" that were created in addition to my datatables.
Now it seems to work, but a bit cumbersome I think.
Thanks again.

Looks like an issue with EF.

BTW, I am using ASP.NET MVC 4 beta + Web API on VS 2010 (w/ .NET 4).
Any ideas?

Enums and all other new EF 5.0 features are dependent on .NET 4.5 (VS11) - both currently in Beta. If you run EF 5.0 in VS 2010 you get mostly the same functionality as in EF 4.3.1 = no enums.

How did My Object Get into ASP.NET Page State?

I know what this error is, how to fix it, etc.
My question is that I don't know why my current page I am developing is throwing this error when I am not using the foo class directly in any way, nor am I setting anything to the viewstate. I am using postbacks alot, but like I said, I am not storing anything in the viewstate etc one integer.
I am using nhibernate if that is relevant.
Any idea why I need to mark this classes as serializable that arent being used? Where should I start investigating?

Are you perhaps databinding objects of this kind? It's clearly gotten into page state somehow.

I would assume you have enabled some of the caching elements either for query caching, or enabled actual object graph caching of NHibernate (if so probably using the SysCacheProvider which is just HttpRuntime.Cache).
I would recommend regardless of caching usage or not to mark every Domain object as serializable as it's very reasonable at some point that it will either go over the wire or just into a ViewState/Session container.
