Workarounds for uploading file size limits in MVC

Configure the limit upload file size and time in the Web. config file.

You need to set the file upload limit of two attribute values in the configuration file:Maxallowedcontentlength,maxrequestlength allows the length of the uploaded file, and the length of the request, two sizes need to be set consistent, if not consistent, the request length whichever.
maxRequestLength property: Used to prevent server attacks, such as denial of access caused by a user sending large files to the server. Default value is 4096 (4MB)
Executiontimeout Property: Specifies the maximum number of seconds that a request is allowed to execute before an ASP. NET application shuts down automatically. This time-out property is only applicable if the Debug property in the compilation element is false. The default value is 110s.

<system.web>
maxRequestLength= "2147483647" executiontimeout= "36000"/>
</system.web>

<system.webServer>
<security>
<requestFiltering>
<!--<requestlimits maxallowedcontentlength= "1073741824"/>-->
<requestlimits maxallowedcontentlength= "2147483648"/>
</requestFiltering>
</security>
</system.webServer>
