If this property is `false`, even code without <xref:System.Security.Permissions.SecurityPermissionFlag.Execution> can execute. Execution checking is expensive and can eliminate the advantages of lazy policy resolution. This property is provided to disable execution checking when needed.

<format type="text/markdown"><![CDATA[

## Remarks

You can use the <xref:System.Security.SecurityManager.CurrentThreadRequiresSecurityContextCapture%2A> method before you cache sensitive data that is obtained after successful security demands.

If the <xref:System.Security.CodeAccessPermission.Assert%2A> method has been called higher on the stack, the data should not be cached without capturing the corresponding security context. Otherwise, sensitive data that is obtained under an <xref:System.Security.CodeAccessPermission.Assert%2A> may become available to code that is no longer be running with that <xref:System.Security.CodeAccessPermission.Assert%2A> in place.

> [!IMPORTANT]

> The return value is reliable only when it is `false`, which means that the thread is guaranteed not to require a security context capture. The method may return true when a security context capture is not necessary, to avoid security vulnerabilities.

<xref:System.Security.SecurityManager.CurrentThreadRequiresSecurityContextCapture%2A> is security-critical because its main use is to avoid unnecessary security context captures, which indicates that the code using it is security-sensitive and must be audited.

## Remarks

> [!NOTE]

> In the .NET Framework 4, the host evidence in `evidence` must contain <xref:System.Security.Policy.Zone?displayProperty=nameWithType> evidence.

| <xref:System.Security.SecurityZone.MyComputer> | `FullTrust` |

Other evidence, such as <xref:System.Security.Policy.Url> or <xref:System.Security.Policy.Site>, may be considered.

The returned permission set can be used by a sandbox to run the application. Note that this method does not specify policy, but helps a host to determine whether the permission set requested by an application is reasonable. This method can be used to map a zone to a sandbox.

## Remarks

The recommended alternative to this method is to use the URL and Zone evidence for the executing assembly to call <xref:System.Security.SecurityManager.ResolvePolicy%2A> for each evidence type. The permission sets returned from the <xref:System.Security.SecurityManager.ResolvePolicy%2A> calls identify the permissions granted to the executing assembly based on its zone and URL of origin.

> This member makes a link demand for the ECMA public key, which is not a valid cryptographic key but a pseudo key. Within the .NET Framework the link demand for the ECMA pseudo key is automatically converted to a link demand for the Microsoft public key. The security exception is based on the Microsoft public key, not the ECMA pseudo key.

<returns>An enumerator for <see cref="T:System.Security.Policy.PolicyLevel" /> objects that compose the security policy hierarchy.</returns>

<format type="text/markdown"><![CDATA[

## Remarks

The returned enumerator provides successive <xref:System.Security.Policy.PolicyLevel> objects that represent the policy at the respective (machine, user, enterprise, application domain) level of the hierarchy. These objects are the live policy objects; altering these objects can have unpredictable results.

Minimum policy hierarchy consists of a machine level, an enterprise level, and a user level. However, the hierarchy can include additional levels.

<returns>The set of permissions that is appropriate for all of the provided evidence.</returns>

<format type="text/markdown"><![CDATA[

## Remarks

This method invokes the security policy engine, providing it with an array of <xref:System.Security.Policy.Evidence> objects. The returned permission set represents only those permissions that apply to every evidence in the array. These permissions are either equivalent to, or a subset of the permissions that policy would have granted to each individual evidence. This method behaves as if you were performing an intersection on the results of resolving policy on each of the <xref:System.Security.Policy.Evidence> objects in the array.

## Remarks

This method invokes the security policy engine, providing it with evidence of the calling code's identity and the set of permissions the code requests. The result is determined by the security policy. This method returns the set of permissions that would be granted by the security system, and returns the set of permissions that would be denied as an output parameter. The effective granted permissions are those in the granted set that are not in the denied set.
