Boa Tarde,
Criei um WebPart no Visual Studio 2010 e fiz o deploy no SharePoint 2010 Foundation. Essa WebPart simplesmente cria um objeto WebRequest. Porém ocorre o erro descrito abaixo.
O mais intrigante é que já tentei várias coisas, como por exemplo alterar o trust level para "Full", adicionei no arquivo da solução do VSTDIO "Package.Template.xml" o elemento "CodeAccessSecurity" e não obtive
êxito.
Se alguém tuver alguma dica, agradeço.
Código:
string myUrl = "http://localhost/";
WebRequest req = WebRequest.CreateDefault(new Uri(myUrl));
Package.Template.xml:
<CodeAccessSecurity>
<PolicyItem>
<PermissionSet class="NamedPermissionSet" version="1">
<IPermission class="SecurityPermission" version="1" Flags="Execution" />
<IPermission class="AspNetHostingPermission" version="1" Level="Minimal" />
<IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" version="1" ObjectModel="True" />
<IPermission class="System.Net.WebPermission" version="1" Unrestricted="true" Connections="true">
<ConnectAccess>
<URI uri="https?://.*" />
</ConnectAccess>
</IPermission>
</PermissionSet>
<Assemblies>
<Assembly Name="$SharePoint.Project.AssemblyName$" Version="$SharePoint.Project.AssemblyVersion$" PublicKeyBlob="$SharePoint.Project.AssemblyPublicKeyBlob$" />
</Assemblies>
</PolicyItem>
</CodeAccessSecurity>
