ICLRHostBindingPolicyManager::ModifyApplicationPolicy Method

Modifies the binding policy for the specified assembly, and creates a new version of the policy.


HRESULT  ModifyApplicationPolicy (  
    [in] LPCWSTR     pwzSourceAssemblyIdentity,
    [in] LPCWSTR     pwzTargetAssemblyIdentity,  
    [in] BYTE       *pbApplicationPolicy,  
    [in] DWORD       cbAppPolicySize,  
    [in] DWORD       dwPolicyModifyFlags,  
    [out, size_is(*pcbNewAppPolicySize)] BYTE *pbNewApplicationPolicy,
    [in, out] DWORD *pcbNewAppPolicySize  


[in] The identity of the assembly to modify.

[in] The new identity of the modified assembly.

[in] A pointer to a buffer that contains the binding policy data for the assembly to modify.

[in] The size of the binding policy to be replaced.

[in] A logical OR combination of EHostBindingPolicyModifyFlags values, indicating control of redirection.

[out] A pointer to a buffer that contains the new binding policy data.

[in, out] A pointer to the size of the new binding policy buffer.

Return Value

HRESULT Description
S_OK The policy was modified successfully.
E_INVALIDARG pwzSourceAssemblyIdentity or pwzTargetAssemblyIdentity was a null reference.
ERROR_INSUFFICIENT_BUFFER pbNewApplicationPolicy is too small.
HOST_E_CLRNOTAVAILABLE The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.


The ModifyApplicationPolicy method can be called twice. The first call should supply a null value for the pbNewApplicationPolicy parameter. This call will return with the necessary value for pcbNewAppPolicySize. The second call should supply this value for pcbNewAppPolicySize, and point to a buffer of that size for pbNewApplicationPolicy.
